Standard House Rules — the most widely played version. Official World Series of Beer Pong (WSOBP) rules noted where they differ.
🏓 Setup
10 cups per side in a 4-3-2-1 triangle. Cup tips point toward center. Fill each cup to desired level (standard: 2.4 oz). One water rinse cup per side. Table: 8 ft x 2 ft standard. 2 balls. 2 teams of 2 players.
⚾️ Taking Your Turn
Teams alternate turns. Each player on a team throws one ball per turn (2 throws per turn for a 2v2 game). Players must keep their elbow behind the table edge when throwing (elbow rule). If both players hit cups in the same turn, the balls roll back and the team shoots again (rollback/bonus).
🎯 Scoring
Ball lands in a cup: that cup is removed and the defending team drinks it. Ball bounces off table then lands in cup (bounce shot): worth 2 cups in most house rules, but defending team may swat it after it bounces. Ball hits cup rim and bounces in air: can be grabbed or blown out before it settles (finger/blow rule). WSOBP: bounce shots are not allowed.
🔄 Rerack / Rack
When a team reaches 6 cups remaining: optional rack into 2-row triangle. At 3 cups: triangle of 3. At 1 cup: center it. Teams get 2 reracks per game. Rerack must be called before throwing. Shooting team chooses when to use their allotted reracks.
🚧 Redemption (Rebuttal)
When the final cup is hit, the losing team earns a redemption round. Each player shoots until they miss. If all remaining cups are hit during redemption, overtime begins: 3 cups per side, closest triangle. No reracks in overtime. Last cup may be centered.
🏆 Special Plays
Both balls in same cup: instant win in most house rules (death cup), or 3 cups removed in WSOBP. Island: if a cup is surrounded by empty space, call it before throwing — a hit removes it plus another cup of your choice (once per player per game). Balls back after rollback: maximum 3 cups per turn in WSOBP.
💧 Hygiene
Rinse balls in the water cup before every throw. Never use the water cup as a drinking cup. Replace water cups when visibly dirty. Professional tournaments use water in game cups with personal drinks on the side to avoid contamination. Balls regularly contact floors, tables, and hands.
Beer quantity calculations are based on the standard cup fill formula (2 beers per 10 cups per team) established by widely practiced house rules and BPONG.COM guidelines. Tournament game counts use standard single and double elimination bracket formulas.

Complete Beer Pong Guide: Rules, Setup, and Party Planning
Beer pong — also known as Beirut — is one of the most popular party and social drinking games in the United States and increasingly worldwide. Whether you are organizing a casual backyard game for friends or planning a structured tournament with multiple tables and 20+ players, getting the supplies right means the party flows without interruption. This guide covers setup, rules, and exactly how much beer, cups, and balls you need to buy.
How Many Cups and How Much Beer for Beer Pong
The standard game uses 10 cups per side (20 cups total) arranged in a 4-3-2-1 triangle formation. The traditional fill is 2 standard 12 oz beers per side — split among 10 cups, this gives approximately 2.4 oz per cup. For 5 games in an evening with 4 players, that is 10 sides total consuming approximately 20 beers in cups plus additional social drinking. A practical planning formula: buy 1 case (24 beers) for every 5 to 6 games for a standard 4-player setup with moderate drinking between games.
For cups: each game uses 20 active cups plus 2 water rinse cups = 22 cups minimum. Because cups get knocked over, cracked, or contaminated during a night of play, always add a 30% buffer. For 5 games on 1 table: 5 × 22 × 1.3 = approximately 140 cups. Buy 150 cups per table for a comfortable evening with no shortage.
Beer Pong Table Size and Setup
The official beer pong table is 8 feet long and 2 feet wide — the same dimensions as a standard folding banquet table. Table height should be approximately 27.5 to 30 inches (standard dining table height). The 8-foot length is critical to the game's balance: shorter tables are too easy, longer tables too difficult for casual play.
Cup placement: the 4-cup back row aligns with the short end of the table (back edge). The triangle tip (single cup) points toward the center of the table. Both teams' formations should mirror each other symmetrically. Cups should touch each other when in full formation — gaps make throws easier and the formation less satisfying to dismantle. Place one water rinse cup off to the side of each formation, not in play.
Tournament Planning: Brackets and Supplies
Single elimination tournaments require one fewer game than the number of teams: 8 teams = 7 games, 16 teams = 15 games, 32 teams = 31 games. With 2 tables running simultaneously, an 8-team single elimination bracket completes in approximately 2 hours (3 rounds, first round = 4 simultaneous games, then 2, then final). For 16 teams with 4 tables, complete in approximately 2 to 3 hours.
Supply estimate for an 8-team (16-player) single elimination tournament: 7 games × 24 oz beer per side × 2 sides = 168 oz beer for cups = approximately 14 beers. Plus social drinking at 1 beer per player per round: 16 players × 3 rounds = 48 beers. Total: approximately 62 beers = 3 cases. Always round up to the nearest case. For 16 teams: 5 to 6 cases minimum.
Playing Beer Pong Without Alcohol
Beer pong is completely playable with non-alcoholic beverages. Fill cups with water, juice, soda, or any other drink. The game mechanics are identical — the only difference is the consequence of losing a cup. Many regular players prefer water in cups (keeping a personal drink on the side) for hygiene reasons: shared cups with balls that have bounced off floors and tables are not ideal from a contamination standpoint. The World Series of Beer Pong uses water in all competition cups for exactly this reason.
Frequently Asked Questions
Standard beer pong uses 10 cups per side (20 active cups total) plus 2 water rinse cups (one per side) = 22 cups minimum per game. For a full evening with 5 games on one table, buy 150 cups minimum (22 per game × 5 games × 1.3 buffer factor = 143, rounded up). Cups get knocked over, cracked, or contaminated during a party, so always buy at least 30% more than the calculated minimum. For a tournament with 8 teams and 7 games, buy 250 to 300 cups for 2 tables running simultaneously.
For 20 players (10 teams) playing a full evening of single elimination tournament games (9 games total) with moderate drinking: cup beer ≈ 9 games x 48 oz (4 beers) = 432 oz = 36 standard 12 oz beers. Social drinking between games: 20 players x 3 rounds x 1 beer = 60 beers. Total: approximately 96 beers = 4 cases. Buy 4 to 5 cases to be safe. If using the larger single elimination bracket for 16 teams, add another case. Always have more than you think you need.
When a team has 6 cups remaining, they can request a rerack — rearranging the remaining cups into a tighter triangle. Standard rerack positions: 6 cups = 3-2-1 triangle, 3 cups = triangle of 3, 1 cup = center it. Most house rules allow 2 reracks per game total. The defending team rearranges the cups when their turn comes (after their throw). Reracks must be called before the shooting team throws — you cannot call a rerack mid-turn. The shooting team chooses the timing of their rerack requests.
The elbow rule requires that a player's elbow must not cross the front (near) edge of the table when throwing. If it crosses, the shot does not count. Some house rules extend this to wrists (the "wrist rule"). The rule prevents players from leaning too far over the table to artificially shorten the throwing distance. This is the most commonly argued-about rule at casual parties. At WSOBP tournaments, a referee enforces it consistently. For house games, agreeing before play on whether wrists apply avoids mid-game arguments.
In most house rules this is called a "death cup" — an instant game win for the shooting team. Some house rules instead apply a 3-cup penalty (the hit cup plus 2 chosen by the shooting team) plus balls roll back. In WSOBP official rules: if both balls land in the same cup, the defending team removes 3 cups total (the hit cup + 2 of the defending team's choice) and the balls roll back for another turn. Agreeing on which variation you are using before the first game eliminates this common dispute.
Sink balls into all 10 of the opponent's cups before they eliminate yours. After the last cup is hit, the losing team earns a redemption round — each player shoots until they miss. If the losing team sinks all remaining cups during redemption, overtime begins with 3 cups per side (no reracks in overtime, last cup can be centered). The game ends when one team eliminates all opponent cups without the opponent completing a successful redemption round. A shutout (winning with the opponent scoring zero) typically comes with a predetermined social consequence.
A bounce shot is when a player bounces the ball off the table surface into a cup. Under most house rules, a successful bounce shot counts as 2 cups instead of 1 (the made cup plus one extra chosen by the shooting team). The trade-off: the defending team can swat or grab the ball after it bounces off the table, potentially preventing the shot. Direct arc shots cannot be defended. WSOBP does not permit bounce shots — all shots must travel directly from hand to cup. Agree on bounce rules before play.
In many house rules, if a ball is spinning around the inside rim of a cup without fully settling in the liquid, a player may blow it out or flick it out with a finger before it touches the liquid. This is called the "finger/blow" rule. If the ball touches the liquid before being deflected, the cup is made and must be drunk. This rule is a popular house addition that is not in official WSOBP rules. Some parties enable one or both (blow and finger), others just one. Always agree before the first game.
The game uses 2 balls per table. However, balls frequently roll off tables, bounce under furniture, or get stepped on and cracked during a party. Buy 6 to 8 balls per table minimum for a full evening of play. For a 4-table tournament night, 20 to 24 balls ensures continuous play without hunting for lost balls. Standard 40mm 3-star table tennis balls are ideal — they bounce predictably and survive more drops than cheap unrated balls. Available in packs of 12 to 72 at sports stores or online.
The island rule (also called solo or sniper) applies when a single cup is surrounded by empty space — not touching any other remaining cups. A player can call out "island" before throwing, and if they hit that specific isolated cup, an additional cup is removed (the island cup plus one of the defending team's choice). If they miss or hit a different cup while calling island, the missed throw counts as a normal miss. Each player can use the island call once per game. Not in WSOBP official rules.
Single elimination is the simplest format: teams are seeded (or randomly drawn), and losers are eliminated each round. For 8 teams: Round 1 has 4 games, Round 2 has 2 games, Final has 1 game — 7 total games. With 2 tables: Round 1 runs simultaneously (4 games across 2 rounds of 2), taking about 40 to 60 minutes per round. Double elimination gives teams a second chance after one loss but takes nearly twice as long. Round robin (every team plays every other team) is most fair but impractical above 8 teams due to time requirements.
The standard and most iconic cup is the 16 oz or 18 oz red plastic solo-style cup. These have visible ridgelines that can be used to measure fill levels (bottom ridge = about 1 oz, second ridge = about 3 oz). The 18 oz size is marginally easier to make due to the slightly larger opening. WSOBP uses 22 oz fluted stadium cups. For casual play, any 16 oz plastic cup works. Avoid smaller cups below 12 oz as they significantly change game difficulty and reduce the drinking component. Colorful cups work but the classic red is universally recognized.
The most common method is "eyes" — one player from each team makes eye contact with their opponent and both throw simultaneously. The team that sinks their ball first gets the first turn in the game. If neither or both sink, repeat. Some groups use rock-paper-scissors or a coin flip instead. The eyes method is used in WSOBP tournaments. For subsequent games, the winning team from the previous game typically goes first, or the team that just won gets to choose whether to start or allow the other team to go first.
Traditional beer pong has real hygiene concerns — balls regularly bounce off floors, hands, and tables before being rinsed in shared water cups that can still harbor bacteria. Research published in scientific journals has shown that water rinse cups can still contain E. coli and other bacteria. Practical hygiene improvements: use water in game cups with personal drinks on the side (eliminates the ball-in-drink issue), change water rinse cups every few turns, use fresh balls when visibly dirty, and sanitize hands before playing. Tournament play typically uses water in cups for all these reasons.
