Drinking Roulette Rules: Setup, Zero and Empty Glasses

How to Play Drinking Roulette: Clear Rules for Four Players

Contents

To play drinking roulette, also called shot roulette, take turns spinning the wheel with one ball, read the result, find the glass with that number printed on it and follow the consequence agreed before play. You can play entirely alcohol-free with water, juice or points instead of drinking. There is no universal rulebook: below is one concrete house version you can agree on before starting.

What do you need, and how do the numbers work?

You need a wheel, one ball, clearly marked glasses, known contents and a stable table. Check the number-to-glass mapping before the first turn, and use your own cup for drinking or another agreed hygienic arrangement.

Glass capacity varies by set; there is no universal 30 ml requirement. Never add alcohol secretly or change a beverage’s contents without telling everyone.

The EZ Drinker manufacturer sheet lists 16 glasses and two balls, with a set of matching numbers on each glass. This is an undated manufacturer document, not confirmation of the package contents on a particular date. A spare ball is not an instruction to use two balls at once or double the consequences.

Sixteen glasses do not necessarily mean 16 wheel sectors. Read the actual labels, including 0 and 00 if present. If the ball lands on 9, use the glass that actually has 9 printed on it—not whichever glass happens to be nearest the ball.

Which house rules should you choose?

For this guide, only the active player follows the result. Play clockwise, with one individual spin per turn and no requirement to drink a whole glass.

Another version assigns glasses to their owners before play. Keep these arrangements separate:

VersionWho follows the result?What matters?
Active-player version—our choiceOnly the person taking the turnA fixed order gives each person a known number of turns
Assigned-glass versionThe owner of the matching glassAn owner’s probability depends on how many wheel numbers lead to their glasses, not simply how many glasses they own

Counting assigned numbers gives probabilities only if the relevant wheel outcomes are assumed equally likely. The set itself does not establish that a physical wheel is perfectly fair.

How do four players take their turns?

Give each player at most two turns: eight spins altogether. Stop after the eighth completed spin, regardless of any remaining beverages.

  1. Check the set. Put the wheel on a stable table and read the numbers on the wheel and glasses.
  2. Announce the contents. For a fully alcohol-free example, use water and juices whose ingredients everyone knows. Each person may choose a beverage, points or a pass.
  3. Agree on the consequence. When a filled glass is selected, the active player may take the agreed portion of its beverage in their own cup. Drinking the entire glass is not required, and anyone may decline at any time.
  4. Set the order. Play clockwise. One turn means one individual spin, not a full circuit of all players.
  5. Read the result. Match the printed number and apply the table below.
  6. Refill only if agreed. You may take a portion or pass. If refilling is agreed, you may restore a selected glass to its starting volume with the same known contents only. With no refill, mark the glass as used and out of play as soon as it is first selected; you may remove it from the table. You do not have to finish any remaining drink: the glass is unavailable even if it still contains liquid. Any later hit on one of its printed numbers is a pass and counts as a scheduled turn, with no re-spin.
  7. Stop after eight spins. Do not add turns to finish the beverages.

For optional scoring, predict a number before your spin and earn one point for an exact match, with no penalty for a wrong prediction. Scores and refusals never trigger extra portions.

What happens on zero, an empty glass or a repeated number?

In this house version, zero, an unmapped number and an empty glass all mean pass. A repeated number follows the normal rule if its glass is still filled; it does not trigger another spin.

These are agreed house rules, not official manufacturer rules.

SituationAction
The result is 0 or 00Pass without a beverage consequence
No glass has the result printed on itPass; do not choose the nearest glass
The matching glass is emptyPass; do not spin again
A filled glass’s number appears againFollow the normal agreed consequence
The ball leaves the wheelRepeat the spin without a consequence for the failed attempt
A player does not want to drinkChoose points or pass without a penalty
The turn limit is reachedStop, even if glasses remain full

Avoid last-person-standing rules, doubled portions, speed contests and hidden alcohol.

How many portions does the plan allow for?

If every result maps to a filled glass and nobody skips, each individual turn provides one portion opportunity. This is a beverage-volume model, not a recommendation to consume the calculated amount.

With eight spins and four players in a fixed clockwise order, each person gets exactly two portion opportunities. The turns are not allocated unevenly by chance.

With 16 turns and three players, the order gives 6, 5 and 5 turns. The group average is 5.3, rounded to one decimal place; nobody actually receives 5.3 turns or portions. Assigned-glass ownership, skips and no-refill rules change this calculation.

In an ideal model with 16 equally likely glasses and no refill, 16 spins select about 10.3 distinct glasses on average, not 16. Repeated hits land on glasses already marked as used and taken out of play after their first selection, whether or not anyone drank from them. This counts selections, not prescribed consumption. This mathematical assumption does not establish that a real wheel is fair or that all 16 glasses have equal probability.

What does the turn comparison show?

The chart shows planned total turns divided by player count, assuming one portion opportunity per turn. It does not show actual consumption or a safe drinking limit.

Planned turnsPlayersGroup-average portion opportunities
1635.3
1644.0
1662.7
1682.0
632.0
661.0
1042.5

These are conditional planning ratios, rounded to one decimal place. They are not determined by glass count, dice or card probabilities, and they are not safety caps. In a fixed order, individuals receive whole numbers of turns; passes reduce beverage consequences.

How do you use the planner, and what are its limits?

Use the planner to estimate beverage volume for a chosen number of individual spins. It does not model the wheel’s number mapping, empty glasses, refusals or alcohol strength.

Enter this four-player example using the actual interface controls:

Interface labelSetting
PLAYERS4
GLASS COUNT16 glasses
ROUNDS8—interpreted here as eight individual spins
SHOT SIZE (OZ)0.5 oz (15 ml)

The last option is the exact interface label. It represents 0.5 fluid ounces, approximately 15 ml, not a standard alcoholic drink.

At these settings, the local widget displays 8 portions, 2.0 per person, 4.0 oz and 118 ml. Its 12 min duration uses a hardcoded estimate of 1.5 minutes per spin, not measured playing time.

Screenshot of the actual English interface on localhost, using 4 / 16 / 8 / 0.5. This is not a test of the production website.

Keep these limitations beside the calculation:

  • Glass count is selectable but unused in the formula. Choosing 6 instead of 16 leaves these outputs unchanged.
  • 118 ml covers eight portions, not an initially filled tray. Filling 16 glasses with 0.5 oz each requires 8 oz, approximately 237 ml.
  • The total uses 29.57 ml per fluid ounce. The rounded 15 ml option label is not the multiplier used for the total.
  • TOTAL DRINKS and DRINKS / PERSON refer to modeled portions, not standard alcoholic drinks. The model does not calculate ABV, pure alcohol content or BAC.
  • PERFECT SETUP is an interface verdict, not a medical assessment, a guarantee of fun or an individual drinking limit.
  • The widget’s disclaimer about random allocation is inaccurate for this strictly alternating active-player version: eight turns among four players give exactly two turns each. Passes and refusals can still change actual portions taken.

How can you play without a wheel?

Use dice, cards or a configurable number picker to select a labeled cup. Juice, water or points work well with the same turn order and right to pass.

MethodSetupProbability and limitations
One fair dieSix cups labeled 1–6Each cup has probability 1/6
Two fair diceEleven cups labeled 2–12Sums are not uniform: 7 has probability 6/36, or 16.7%; 2 and 12 each have 1/36, or 2.8%
CardsTen cups labeled 1–10; 40 cards with ranks A–10Each rank has a 10% probability on the first draw from a shuffled deck
Configurable number pickerCups labeled 1–N and the same range in the toolCheck its range and selection method; standard casino labels 0–36 do not match this setup

With one die: label six cups, roll once on your turn and select the matching cup. You do not need a second die.

With two dice: label cups 2–12, roll both dice and add their values. Do not assign a strong alcoholic beverage to 7: that sum occurs more often than the extremes.

With cards: remove jacks, queens, kings and jokers. This leaves 40 cards, with four of each rank from ace to ten. Ace means 1; suit does not affect cup selection. Shuffle and draw one card per turn. Draws without replacement are dependent. Reshuffle the whole deck after 40 draws, or replace the card and shuffle after every turn for the independent-draw model.

With a number picker: set the range to exactly 1–N, where N is the number of labeled cups. Do not use a tool that cannot accept the required labels.

A spinning bottle can serve as a house-rule pointer, but boundaries between cups may be ambiguous and its fairness is not certified.

Which optional variations are worth adding?

Add only clear, agreed changes: leave used glasses empty, guess a known juice flavor or answer a question for a point with the right to pass.

  • No refill: when a glass is first selected, you may take a portion or pass, then mark it as used and out of play; you may remove it from the table. You do not have to finish any remaining drink. A later hit on any of its printed numbers is a pass and counts as a scheduled turn, with no re-spin.
  • Guess the juice: everyone knows the available beverages and ingredients; the player may guess the selected juice’s flavor.
  • Questions or points: answer an agreed question instead of taking a beverage, or decline without a penalty. Avoid unsafe dares and demands to reveal private messages or contact someone.

An alcohol-free version is a complete game for the whole group, not merely a substitute role for one nondrinker. For a different card-based party game, see the Irish Poker rules; it is not poker played for money.

What should you remember about alcohol and health?

If alcohol is involved, follow local age laws and do not drive after drinking. The US drinking age of 21 is not a universal rule.

WHO states that no level of alcohol consumption is safe for health. Water and food do not cancel alcohol’s effects or make a chosen amount safe.

If someone has severe confusion, slow or irregular breathing, a seizure or loss of consciousness, stop and call local emergency services. Stay with them and follow the dispatcher’s instructions. The NHS alcohol-poisoning guidance, dated June 4, 2026, advises giving water only if the person is awake, can swallow and is not vomiting; do not use coffee, a cold shower or forced vomiting. The UK number 999 is not a worldwide emergency number.

FAQ

Frequently Asked Questions

No. If your wheel has both 0 and 00, they are separate labels. Check the mapping for each and agree on their treatment before playing. In this guide’s house version, both mean pass.

Several wheel results can map to the same glass. Read the complete set of numbers printed on each glass. The number of glasses does not tell you how many sectors the wheel has.

Yes. Alternate turns and agree on a fixed number of spins per person. Four players are used here to make the example clear, not because four are required.

No. A portion here is a chosen volume of beverage. The planner does not account for alcohol strength, pure alcohol content or blood alcohol concentration.

No. Stop at the agreed turn limit even if some glasses are still full. Finishing the drinks is not a condition of completing the game.
