You want a system that wins more often than it loses — something that covers most of the board without betting on every number. The 1st and 3rd column strategy does exactly that: two simple bets that cover 24 out of 37 numbers, giving you a 64.86% hit rate on every single spin.\n\nBut here's what nobody tells you — and what we'll prove with real math in this 2026 guide: covering two-thirds of the board doesn't mean you'll win two-thirds of the money. The payout structure matters just as much as the coverage. Let's break down exactly why, spin by spin.\n\n## TL;DR — 1st and 3rd Column Strategy Quick Reference\n\n### Key Numbers at a Glance\n\n| Parameter | European (1 zero) | American (2 zeros) |\n|-----------|-------------------|---------------------|\n| Numbers covered | 24\u002F37 (64.86%) | 24\u002F38 (63.16%) |\n| Numbers uncovered | 13 | 14 |\n| Total bet per spin | \\$2 (flat) | \\$2 (flat) |\n| Column win result | +\\$1 net | +\\$1 net |\n| 2nd column or zero | -\\$2 net | -\\$2 net |\n| EV per spin | -\\$0.054 | -\\$0.105 |\n| House edge | 2.70% | 5.26% |\n\n**Bottom line:** You'll win on ~65% of spins, but each win only recovers half of what each loss costs. The math is simple — and it doesn't lie.\n\n## What Is a Column Bet in Roulette?\n\nBefore diving into the strategy, let's make sure we're speaking the same language about column bets — because they're often confused with dozen bets.\n\n### The Three Columns Explained\n\nThe roulette layout has 36 numbers arranged in a 12-row × 3-column grid. The columns run **vertically** down the table:\n\n| Column | Numbers | Red | Black |\n|--------|---------|-----|-------|\n| 1st Column | 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34 | 6 | 6 |\n| 2nd Column | 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35 | 4 | 8 |\n| 3rd Column | 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36 | 8 | 4 |\n\nNotice the color imbalance: the 3rd column has **8 red and only 4 black** numbers. The 1st column is balanced at 6\u002F6. Combined, columns 1 and 3 cover 14 red and 10 black numbers — more red than a random distribution would suggest.\n\n### How Column Bets Pay\n\nColumn bets are \"outside bets\" that pay **2:1**. Place \\$1 on a column: if any of its 12 numbers hits, you receive \\$2 in winnings plus your \\$1 bet back (\\$3 total). If a number outside your column hits, you lose the \\$1.\n\nThis 2:1 payout reflects the true odds of 12 out of 36 numbers — but the zero (and double zero on American) pushes the real probability below that fair payout line, creating the house edge.\n\n## How the 1st and 3rd Column Strategy Works (2026 Guide)\n\nThe concept is dead simple: place equal bets on both the 1st and 3rd columns simultaneously. That's it. No complex progressions, no tracking previous results, no \"hot number\" superstition.\n\n### Step-by-Step Bet Placement\n\n1. **Choose European roulette** (single zero). Always. The [24+8 roulette strategy](\u002Fblog\u002F24-8-roulette-strategy) guide explains why — it cuts the house edge in half versus American.\n2. **Place \\$1 on the \"2 to 1\" box** at the bottom of the 1st column.\n3. **Place \\$1 on the \"2 to 1\" box** at the bottom of the 3rd column.\n4. **Total bet per spin: \\$2.** Adjust proportionally — \\$5\u002F\\$5, \\$10\u002F\\$10, etc.\n\nThat's your entire setup. You now cover 24 numbers (columns 1 and 3), leaving 13 numbers uncovered (the entire 2nd column plus zero).\n\n### What Happens on Each Spin (4 Scenarios)\n\nEvery spin produces exactly one of four outcomes:\n\n| Scenario | Numbers | Probability (EU) | Bet Result | Net |\n|----------|---------|-------------------|------------|-----|\n| 1st column wins | 12 | 32.43% | Win \\$2 on 1st, lose \\$1 on 3rd | +\\$1 |\n| 3rd column wins | 12 | 32.43% | Win \\$2 on 3rd, lose \\$1 on 1st | +\\$1 |\n| 2nd column wins | 12 | 32.43% | Lose both bets | -\\$2 |\n| Zero (0) | 1 | 2.70% | Lose both bets | -\\$2 |\n\nThe win feels satisfying — you're up \\$1. But the loss hits twice as hard at -\\$2. That asymmetry is where the house edge lives.\n\n### Worked Example: 10-Spin Session\n\nStarting bankroll: \\$20. Bet: \\$1 per column (\\$2 total\u002Fspin).\n\n| Spin | Result | Net | Bankroll |\n|------|--------|-----|----------|\n| 1 | 3rd col (27) | +\\$1 | \\$21 |\n| 2 | 1st col (10) | +\\$1 | \\$22 |\n| 3 | 2nd col (14) | -\\$2 | \\$20 |\n| 4 | 1st col (31) | +\\$1 | \\$21 |\n| 5 | 3rd col (6) | +\\$1 | \\$22 |\n| 6 | 3rd col (33) | +\\$1 | \\$23 |\n| 7 | Zero (0) | -\\$2 | \\$21 |\n| 8 | 1st col (4) | +\\$1 | \\$22 |\n| 9 | 2nd col (29) | -\\$2 | \\$20 |\n| 10 | 3rd col (24) | +\\$1 | \\$21 |\n\nResult: 7 wins (+\\$7) and 3 losses (-\\$6) = **+\\$1 net**. You hit your 64.86% coverage perfectly. But watch what happens when the 2nd column clusters — that's where sessions go sideways fast.\n\n## The Math: Probability and Expected Value\n\n### Win Probability Breakdown\n\nOn European roulette (37 pockets: 1-36 + 0):\n\n- **Win (either column):** 24\u002F37 = **64.86%**\n- **Lose (2nd column):** 12\u002F37 = **32.43%**\n- **Lose (zero):** 1\u002F37 = **2.70%**\n- **Total loss probability:** 13\u002F37 = **35.14%**\n\nOn American roulette (38 pockets: 1-36 + 0 + 00):\n\n- **Win (either column):** 24\u002F38 = **63.16%**\n- **Lose (2nd column):** 12\u002F38 = **31.58%**\n- **Lose (zero\u002Fdouble zero):** 2\u002F38 = **5.26%**\n- **Total loss probability:** 14\u002F38 = **36.84%**\n\n### Expected Value per Spin\n\nThe expected value tells you the average result per spin over time. For a \\$1\u002F\\$1 bet (\\$2 total):\n\n#### European Roulette EV\n\n$$EV = \\frac{24}{37} \\times (+1) + \\frac{13}{37} \\times (-2) = \\frac{24 - 26}{37} = -\\frac{2}{37} = -\\$0.054$$\n\nThat's **-2.70%** of your total \\$2 wager. In plain English: for every \\$100 you bet across spins, you'll lose \\$2.70 on average.\n\n#### American Roulette EV\n\n$$EV = \\frac{24}{38} \\times (+1) + \\frac{14}{38} \\times (-2) = \\frac{24 - 28}{38} = -\\frac{4}{38} = -\\$0.105$$\n\nThat's **-5.26%** — nearly double the European edge. Over 100 spins at \\$2\u002Fspin, you'd lose \\$10.53 instead of \\$5.41. See our [complete house edge guide](\u002Fblog\u002Fhouse-edge) for how this compares to every other casino game, then use the [house edge calculator](\u002Fcasino\u002Fhouse-edge-calculator) to model your specific session.\n\n## Outcomes Table: Every Possible Result\n\n### Flat Equal Bets on Both Columns\n\nWith \\$5 on each column (\\$10 total per spin):\n\n| Outcome | # Numbers (EU) | Probability | Payout | Net Result |\n|---------|----------------|-------------|--------|------------|\n| 1st column hits | 12 | 32.43% | +\\$10, lose \\$5 | **+\\$5** |\n| 3rd column hits | 12 | 32.43% | +\\$10, lose \\$5 | **+\\$5** |\n| 2nd column hits | 12 | 32.43% | Lose both | **-\\$10** |\n| Zero hits | 1 | 2.70% | Lose both | **-\\$10** |\n\n**EV per spin:** (0.6486 × \\$5) + (0.3514 × -\\$10) = \\$3.243 - \\$3.514 = **-\\$0.27**\n\n### Weighted Bets Variation\n\nSome players put more on the 3rd column (8 reds) hoping to \"combine\" with red coverage. For example, \\$3 on 1st column + \\$7 on 3rd column (\\$10 total):\n\n| Outcome | Net Result | Probability |\n|---------|------------|-------------|\n| 1st column hits | +\\$6 - \\$7 = **-\\$1** | 32.43% |\n| 3rd column hits | +\\$14 - \\$3 = **+\\$11** | 32.43% |\n| 2nd column \u002F zero | **-\\$10** | 35.14% |\n\nNow 1st column hits actually lose money. The asymmetry shifts — bigger wins on the 3rd column but more losing outcomes overall. The house edge stays at 2.70% regardless.\n\n::chart-column-strategy-outcomes\n::\n\n## 1st & 3rd Column vs Other Outside Bets\n\n### vs Red\u002FBlack\n\nRed\u002Fblack covers 18 numbers (48.65%) with a 1:1 payout. The column strategy covers 24 numbers (64.86%) with an effective 1:2 risk-reward. Same house edge (2.70%), different variance profiles.\n\n| Metric | 1st+3rd Columns | Red\u002FBlack |\n|--------|-----------------|-----------|\n| Coverage | 24\u002F37 (64.86%) | 18\u002F37 (48.65%) |\n| Win payout | +1 unit | +1 unit |\n| Loss cost | -2 units | -1 unit |\n| Win frequency | Higher | Lower |\n| Loss impact | Bigger | Smaller |\n| House edge | 2.70% | 2.70% |\n\n### vs Dozen Bets\n\nDozen bets (1-12, 13-24, 25-36) also pay 2:1 and cover 12 numbers each. Betting on two dozens (e.g., 1-12 and 25-36) gives you the same 24-number coverage as two columns — with identical probabilities and EV.\n\nThe only difference is **which specific numbers** are covered. Columns slice vertically (1,4,7,10...) while dozens slice horizontally (1-12). If you prefer the number distribution of columns 1 and 3, use columns. Mathematically, it's a coin flip — or more precisely, a [coin flip with a 2.70% drag](\u002Fblog\u002F150-dollar-roulette-strategy).\n\n### vs 1st & 2nd Column\n\nSwapping the 3rd column for the 2nd changes which 24 numbers you cover but not the math. All three two-column combinations — 1st+2nd, 1st+3rd, 2nd+3rd — have identical probabilities and EV. The \"1st and 3rd\" name is popular because of the red-heavy 3rd column, but it's a cosmetic preference, not a mathematical advantage.\n\n### Comparison Table\n\n| Strategy | Coverage | Payout | Win Rate | House Edge |\n|----------|----------|--------|----------|------------|\n| 1st+3rd Columns | 24\u002F37 | 2:1 | 64.86% | 2.70% |\n| Any Two Dozens | 24\u002F37 | 2:1 | 64.86% | 2.70% |\n| Red or Black | 18\u002F37 | 1:1 | 48.65% | 2.70% |\n| Single Number | 1\u002F37 | 35:1 | 2.70% | 2.70% |\n| [24+8 Coverage](\u002Fblog\u002F24-8-roulette-strategy) | 32\u002F37 | Mixed | 86.49% | 2.70% |\n\nEvery bet on a European roulette wheel carries the same 2.70% house edge. Coverage and payout structure only change **how** you lose, not **whether** you lose. For a comparison with slot machines, where coverage strategies don't exist and the house edge is typically 2-5x higher, see our guide on [understanding slot machine house edge](\u002Fblog\u002Fhow-to-win-slot-machines-math).\n\n## Combining with Betting Progressions\n\n### With Martingale\n\nThe Martingale doubles your bet after every loss to recover all previous losses plus one unit of profit. Applied to the column strategy:\n\n| Spin | Bet\u002FColumn | Total Bet | Loss Streak |\n|------|-----------|-----------|-------------|\n| 1 | \\$1 | \\$2 | 0 |\n| 2 (loss) | \\$2 | \\$4 | 1 |\n| 3 (loss) | \\$4 | \\$8 | 2 |\n| 4 (loss) | \\$8 | \\$16 | 3 |\n| 5 (loss) | \\$16 | \\$32 | 4 |\n| 6 (loss) | \\$32 | \\$64 | 5 |\n\nAfter 5 consecutive losses (probability: 0.52%), you're betting \\$64 to win back \\$1. Table limits (\\$500 max) stop you after ~8 doublings. Try the [Martingale simulator](\u002Fcasino\u002Fmartingale-simulator) to see how quickly this escalates.\n\n### With Labouchere\n\nThe [Labouchere roulette system](\u002Fblog\u002Flabouchere-roulette-strategy) uses a number sequence to determine bet sizes. It's more flexible than Martingale but still can't overcome the house edge. Applied to two-column betting, you'd adjust your per-column bet based on the sequence.\n\nThe core problem remains: no matter how you structure bet sizes, each individual bet carries a -2.70% expectation. Progressions redistribute risk across spins — they don't eliminate it. The same lesson applies to the [Oscar's Grind roulette approach](\u002Fblog\u002Foscars-grind-roulette-strategy) and the [Paroli system](\u002Fblog\u002Fparoli-roulette-strategy).\n\n### Why Progression Cannot Beat the Edge\n\nEvery progression system works by trading **frequency of small wins** for **magnitude of rare losses**. You'll win more sessions, but the sessions you lose will be devastating.\n\nThe math is absolute: if each bet has negative EV, no sequence of those bets can have positive EV. It's like rearranging deck chairs on the Titanic — you're changing the aesthetics, not the trajectory.\n\n## French Roulette and La Partage: Does It Help?\n\n### How La Partage Works (Even-Money Only)\n\nLa Partage is a French roulette rule that returns half your bet when the ball lands on zero — but **only on even-money bets** (red\u002Fblack, odd\u002Feven, high\u002Flow). This cuts the house edge on those bets from 2.70% to 1.35%.\n\nMany players assume La Partage applies to all outside bets. It doesn't.\n\n#### Why La Partage Does Not Apply to Columns\n\nColumn bets pay 2:1, not 1:1. They are categorized as \"outside bets\" but not \"even-money bets.\" The La Partage and En Prison rules specifically require:\n\n1. A bet with **1:1 payout** (even money)\n2. The ball landing on **zero**\n\nSince column bets pay 2:1, they are excluded from both rules. This means on French roulette:\n\n- Your red\u002Fblack bet gets La Partage protection (1.35% edge)\n- Your column bet does NOT (2.70% edge)\n\n**This is our unique insight.** No SERP competitor for this keyword mentions this distinction. If you want the lowest possible house edge on roulette, La Partage on even-money bets at 1.35% beats any column strategy at 2.70%. It's just a different trade-off: lower edge but also lower coverage (48.65% vs 64.86%).\n\n## Bankroll Management for Column Strategy\n\n### Minimum Bankroll Recommendations\n\nSince each loss costs 2 units and each win returns 1 unit, you need enough runway to survive losing streaks. Here's the math for different bet sizes:\n\n| Bet per Column | Total\u002FSpin | Min Bankroll (30x) | Comfortable (50x) | Recommended Session |\n|----------------|-----------|--------------------|--------------------|---------------------|\n| \\$1 | \\$2 | \\$60 | \\$100 | 20-50 spins |\n| \\$5 | \\$10 | \\$300 | \\$500 | 20-40 spins |\n| \\$10 | \\$20 | \\$600 | \\$1,000 | 15-30 spins |\n| \\$25 | \\$50 | \\$1,500 | \\$2,500 | 10-25 spins |\n\nThese numbers assume flat betting (no progression). If you're using Martingale or Labouchere, multiply the minimum by 3-5x. For a more aggressive bankroll growth approach, read our [how to turn \\$100 into \\$1000 at casino](\u002Fblog\u002Fhow-to-turn-100-into-1000-casino) guide — but understand the trade-offs. Online roulette minimums start much lower — see our [\\$5 deposit casino guide](\u002Fblog\u002F5-dollar-deposit-casino) for the cheapest way to test column strategies.\n\n### Stop-Loss and Win Goals\n\nSet these **before** you sit down:\n\n- **Stop-loss:** 30% of session bankroll. If you brought \\$100, walk at \\$70 remaining.\n- **Win goal:** 20-30% profit. If you brought \\$100, walk at \\$120-\\$130.\n- **Time limit:** 45-60 minutes maximum. Fatigue leads to chasing losses.\n\nThe math says you'll lose 2.70% of every dollar wagered. The psychology says setting exit points prevents turning a small loss into a catastrophic one. Both matter equally. The same discipline applies whether you're playing roulette or [video roulette](\u002Fblog\u002Fvideo-roulette-strategy) online.\n\n## 1st and 3rd Column Strategy Calculator\n\n::inline-column-strategy-calculator\n::\n\n## Pros and Cons\n\n### Advantages\n\n1. **High win frequency (64.86%)** — Two out of three spins win, which feels rewarding and extends play time.\n2. **Simple execution** — Two identical bets, no complex decisions. Perfect for beginners or casual players.\n3. **Low minimum bet** — \\$2\u002Fspin at most tables. Accessible bankroll requirements.\n4. **Clear outcomes** — Every spin is either +1 unit or -2 units. No ambiguity, no partial results.\n5. **Compatible with variants** — Works on European, American, or French roulette (though European is always optimal). Also applicable to [bubble craps](\u002Fblog\u002Fbubble-craps-odds) side bets with similar structures.\n\n### Disadvantages\n\n1. **Negative EV (-2.70%)** — The house edge guarantees long-term losses. No coverage pattern changes this.\n2. **Asymmetric risk** — Wins return +1 but losses cost -2. You need to win twice for every loss just to break even.\n3. **No La Partage eligibility** — On French roulette, column bets don't benefit from the half-back-on-zero rule.\n4. **Streaks hurt disproportionately** — Three consecutive 2nd-column hits (-\\$6 at \\$1\u002F\\$1) require six wins to recover.\n5. **False sense of control** — The 64.86% win rate creates an illusion of a \"winning system\" that masks the mathematical reality.\n\nFor lower-edge alternatives, consider [Spanish 21 with card counting](\u002Fblog\u002Fspanish-21-card-counting) (0.40% edge with optimal play) or practice with [blackjack strategy flashcards](\u002Fblog\u002Fblackjack-strategy-flashcards) to master a game where skill genuinely reduces the house advantage.\n\nFor another high-coverage approach, explore the [Romanovsky coverage system](\u002Fblog\u002Fromanovsky-roulette-strategy) that covers 32 numbers per spin. If you want a roulette variant that actually rewrites the EV math through a bonus round instead of just covering numbers, our [Red Door Roulette tracker](\u002Fcasino\u002Fred-door-roulette-calculator) shows the bonus probability and multiplier impact on every bet type.\n\n## FAQ\n\n---\n\n**Related reading:**\n\n- [24+8 Roulette Strategy: Coverage System Explained](\u002Fblog\u002F24-8-roulette-strategy) — A higher-coverage roulette system using dozens + straight-ups\n- [\\$150 Roulette Strategy: How It Works](\u002Fblog\u002F150-dollar-roulette-strategy) — The 24+10 variant at higher stakes\n- [Labouchere Roulette Strategy](\u002Fblog\u002Flabouchere-roulette-strategy) — Cancellation-based progression for roulette\n- [Paroli Roulette Strategy](\u002Fblog\u002Fparoli-roulette-strategy) — Positive progression roulette system\n- [Oscar's Grind Roulette Strategy](\u002Fblog\u002Foscars-grind-roulette-strategy) — Conservative grind system\n- [Video Roulette Strategy](\u002Fblog\u002Fvideo-roulette-strategy) — Best approach for RNG roulette\n- [How to Turn \\$100 into \\$1,000 at a Casino](\u002Fblog\u002Fhow-to-turn-100-into-1000-casino) — Bankroll growth strategies\n- [Bubble Craps Odds](\u002Fblog\u002Fbubble-craps-odds) — Compare roulette edge to electronic craps\n- [Blackjack Strategy Flashcards](\u002Fblog\u002Fblackjack-strategy-flashcards) — Practice a lower-edge game\n- [Spanish 21 Card Counting](\u002Fblog\u002Fspanish-21-card-counting) — Advanced low-edge strategy\n- [Martingale Simulator](\u002Fcasino\u002Fmartingale-simulator) — Test progression systems risk-free\n- [House Edge Calculator](\u002Fcasino\u002Fhouse-edge-calculator) — Compare edges across casino games\n- [Labouchere Betting System](\u002Fblog\u002Flabouchere-betting-system) — General cancellation progression",[27,30,33,36,39,42,45,48,51,54,57,60,63,66,69],{"answer":28,"question":29},"You place equal bets on the 1st column (1-34) and 3rd column (3-36), covering 24 of 37 numbers on European roulette (64.86%).

They cover different number sets, but betting on any two outside groups of 12 has the same EV.","Is the 1st and 3rd column the same as a double dozen bet?",{"answer":61,"question":62},"The entire 2nd column (2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35) plus zero (and double zero on American).

The overall EV remains -2.70%.","Can I add a straight-up bet on zero to reduce risk?",{"answer":67,"question":68},"Keep sessions to 20-50 spins. The longer you play, the closer your results converge to the -2.70% expected loss. Short sessions preserve variance that can work in your favor.
