Chuck-a-luck

Chuck-a-luck, also known as birdcage, or sweat rag, is a game of chance played with three dice. It is derived from grand hazard and both can be considered a variant of sic bo, which is a popular casino game, although chuck-a-luck is more of a carnival game than a true casino game. The game is sometimes used as a fundraiser for charity.

Workers play Chuck-a-luck during World War One in France on an improvised board.

Rules

Chuck-a-luck is played with three standard dice that are kept in a device shaped somewhat like an hourglass which resembles a wire-frame bird cage and pivots about its centre. The dealer rotates the cage end over end, with the dice landing on the bottom.

Wagers are placed based on possible combinations that can appear on the three dice. The possible wagers are usually fewer than the wagers that are possible in sic bo and, in that sense, chuck-a-luck can be considered to be a simpler game. In the simplest variant, betters place stakes on a board labelled 1–6. They receive a 1:1 payout if the number bet on appears once, a 2:1 payout if the number appears twice, and a 3:1 payout if the number is rolled all 3 times. In this respect, the basic game resembles Crown and Anchor, but with numbered dice instead of symbols.

Additional wagers that are commonly seen, and their associated odds, are set out in the table below.

Type	Wager	Odds
Single Die Bet	A specific number will appear	1 die, 1 to 1; 2 dice, 2 to 1; 3 dice, 10 to 1 (sometimes 3 to 1)
Any Triple (sometimes offered)	Any of the triples (all three dice show the same number) will appear	30 to 1
Big (sometimes offered)	The total score will be 11 (sometimes 12) or higher with the exception of a triple	1 to 1
Small (sometimes offered)	The total score will be 10 (sometimes 9) or lower with the exception of a triple	1 to 1
Field (sometimes offered)	The total score will be outside the range of 8 to 12 (inclusive)	1 to 1

House advantage or edge

Chuck-a-luck is a game of chance. On average, the players are expected to lose more than they win. The casino's advantage (house advantage or house edge) is greater than most other casino games and can be much greater.

For example, there are 216 (6 × 6 × 6) possible outcomes for a single throw of three dice. For a specific number:

• there are 75 possible outcomes, where only one die will match the number;
• there are 15 possible outcomes, where only two dice will match; and
• there is one possible outcome, where all three dice will match; and
• there are 125 possible outcomes, where no die will match the number.

At odds of 1 to 1, 2 to 1 and 10 to 1 respectively for each of these types of outcome, the expected loss as a percentage of the stake wagered is:

1 - ((75/216) × 2 + (15/216) × 3 + (1/216) × 11) = 4.6%

At worse odds of 1 to 1, 2 to 1 and 3 to 1, the expected loss as a percentage of the stake wagered is:

1 - ((75/216) × 2 + (15/216) × 3 + (1/216) × 4) = 7.9%

If the odds are adjusted to 1 to 1, 3 to 1 and 5 to 1 respectively, the expected loss as a percentage is:

1 - ((75/216) × 2 + (15/216) × 4 + (1/216) × 6) = 0%

Commercially organised gambling games almost always have a house advantage which acts as a fee for the privilege of being allowed to play the game, so the last scenario would represent a payout system used for a home game, where players take turns being the role of banker/casino.

Variants

Bau cua ca cop dice

• Chuck-a-luck is essentially identical to the traditional Vietnamese game Bau cua ca cop.
• A version of the Big Six wheel is loosely based on chuck-a-luck, with various combinations of three dice appearing in 54 slots on a spinning wheel. Because of the distribution of the combinations, the house advantage or edge for this wheel is greater than for chuck-a-luck.
