Official Rules for Popular Dice Games

Dice game rules are deceptively simple on the surface — roll the dice, read the result — but the details underneath determine everything from who wins to whether a game is even legal in a given setting. This page covers the official or most widely accepted rulesets for the most-played dice games in the United States, including how those rules are structured, where they diverge from common practice, and the specific mechanical distinctions that separate one game from another. It draws on published sources, casino gaming regulations, and established game documentation where available.


Definition and scope

The phrase "official rules" for dice games carries real weight in regulated environments and almost none at the kitchen table — which is part of what makes this topic interesting. A game like Craps, played in any Nevada casino, must conform to state gaming commission regulations. The same game played in a garage operates on whatever rules the players agree to before the first roll.

For the purposes of this reference, "official rules" means one of three things: rules codified by a state or tribal gaming authority (as in casino dice games), rules published by a recognized games organization or publisher (as in educational or family dice games), or rules derived from the dominant published source for a given game — such as Hoyle's Rules of Games, which has documented card and dice game conventions since its first publication in the 18th century.

The scope here covers five widely played categories: casino Craps, Yahtzee, Farkle, Bunco, and Liar's Dice. Each has a distinct rule architecture. Readers interested in the broader landscape of game formats can explore the types of dice games reference for a taxonomic view, or visit the main index for the full scope of topics covered across this reference network.


Core mechanics or structure

Craps is built around a two-phase structure. The first phase is the come-out roll: the shooter wins immediately on a 7 or 11 (natural), and loses on a 2, 3, or 12 (craps). Any other number (4, 5, 6, 8, 9, or 10) becomes the "point." In phase two, the shooter re-rolls until hitting the point (win) or a 7 (seven-out, end of turn). The Nevada Gaming Control Board's Minimum Internal Control Standards (MICS) govern table layout, dice specifications, and dealer protocols in licensed Nevada venues.

Yahtzee, published by Hasbro, uses 5 six-sided dice and 13 scoring categories across 13 turns. Each turn allows up to 3 rolls, with the player selecting which dice to keep between rolls. The scoring categories include straights, full house, three/four of a kind, and the eponymous Yahtzee (all 5 dice matching), which scores 50 points. A second Yahtzee in a game earns a 100-point bonus under the official Hasbro rules — a detail that surprises a remarkable number of players who assumed one Yahtzee per game was the ceiling.

Farkle is a push-your-luck game using 6 dice. Scoring dice (1s, 5s, three-of-a-kinds, straights, and other combinations) must be set aside from each roll, and a player may bank their points or roll remaining dice. Rolling no scoring dice — a Farkle — eliminates all points accumulated that turn. Published rules by Legendary Games establish a minimum bank threshold of 500 points before a player can open their score.

Bunco is a social dice game played in rounds across 6 sets, typically with teams of 2. Players roll 3 dice trying to match the target number for each round (1 in round 1, 2 in round 2, etc.). A Bunco — rolling 3 dice matching the target number — scores 21 points and ends the round immediately.

Liar's Dice (also called Perudo) operates on bidding rather than direct scoring. Each player has 5 dice under a cup. Players make ascending bids on the quantity of a given face showing across all dice. A challenged bid reveals all dice; if the bid was too high, the bidder loses a die. The last player with any dice wins.


Causal relationships or drivers

The structure of any dice game's rules is largely a function of three design pressures: randomness management, session length, and social friction reduction.

Games like Craps manage randomness through betting structure — the house edge on a pass line bet is approximately 1.41% (Wizard of Odds, Craps), which is possible to calculate precisely because the rules fix outcomes with mathematical precision. The rules exist partly to make probability calculable.

Yahtzee's 13-category scorecard manages session length by guaranteeing exactly 13 turns per player — no more, no less. The forced fill rule (a player must mark a score each turn, even if it's a zero) adds strategic tension while ensuring the game ends.

Farkle's minimum bank threshold (500 points to open) solves a specific social problem: without it, a player could score 50 points per turn indefinitely and never risk losing them, flattening the game's central tension.


Classification boundaries

Dice games fall into four mechanical archetypes, and the rules differ substantially by type:

  1. Banking games (Craps, Chuck-a-Luck): One player or the house holds a bank; others bet against it. Rules tightly govern payout ratios.
  2. Accumulation games (Yahtzee, Farkle): Players accumulate a score toward a target or compare final totals. Rules govern which combinations score and how.
  3. Social/team games (Bunco): Played in structured rounds with shifting partners. Rules govern round structure and point thresholds rather than individual scoring categories.
  4. Bluffing games (Liar's Dice): Rules govern bidding sequences and challenge resolution rather than dice combinations per se.

The distinction matters for dice game rule disputes, which arise most often at the boundary between categories — players importing expectations from one game type into another.


Tradeoffs and tensions

The central tension in codifying dice game rules is universality versus context-specificity. House rules in Farkle, for instance, vary so widely that the game has no single authoritative text the way Yahtzee does. Legendary Games published a standard, but the game existed as a folk tradition long before any publisher formalized it, and regional variants persist — including one version in which straights (1-2-3-4-5-6) score 1,500 points rather than 1,000.

Casino Craps presents a different tension: regulatory precision versus playability. Nevada's gaming regulations specify dice dimensions (0.75 inches square, within 0.0005 inches of true), inspection intervals, and disposal protocols — rules that would be absurd at a home game but are essential to prevent cheating with loaded and weighted dice in a commercial environment.

The broader challenge for anyone interested in dice game scoring systems is that the "official" label often reflects market dominance rather than independent standards-body designation. Hasbro owns Yahtzee and can publish official rules; Farkle has no equivalent single owner.


Common misconceptions

Misconception 1: Rolling a Yahtzee after all 13 categories are filled still scores 100 bonus points. False. Under official Hasbro rules, the Yahtzee bonus applies only when the Yahtzee box has already been scored with 50 points. If the Yahtzee box was filled with a zero, no bonus applies to subsequent Yahtzees.

Misconception 2: In Craps, a 12 on the come-out roll is a push for pass line bettors. Incorrect. A 12 on the come-out is a loss for pass line bettors (craps), not a push. The push on 12 applies only to the Don't Pass bar — a rule that gives the house its edge on Don't Pass betting.

Misconception 3: In Farkle, a player must roll all 6 dice at the start of each turn. False. A player starts with 6 dice, but if all dice score in a given roll (a "hot dice" situation), the player may pick up all 6 and continue rolling. Only the initial turn begins with a full set by default.

Misconception 4: Bunco is purely luck-based with no decision points. Technically true in terms of dice mechanics — players simply roll as fast as possible — but team composition, score-keeping accuracy, and round transitions involve real coordination, which is why Bunco organizations like the World Bunco Association host structured tournaments.
