This game has complex betting principles and bluffing. You will need three dice for each player and a supply of chips. Throwing cups are recommended because players must conceal their dice from each other. Any number may play, but the game differs with only two.

A game of two handed Bidou consists of three rounds. The winner is the player who wins at least two. Nine chips or counters are placed in the centre of the table. Both players throw a die and the higher becomes captain.

The captain has the first turn throwing the dice and then his opponent. In their turn, players are allowed up to three throws of the dice to try and get the best possible hand, which must be concealed from the other player. All three dice must be rolled in each throw and players must declare how many throws they have taken.

Once both players have determined their hand, betting begins. If the captain's opponent has taken fewer throws, then they become captain and make the first bet or pass.

If both players pass (i.e. decline to bet) then the hand is finished. Once a player has bet, then he alternately either raises (bets a greater amount than the opposing player has just bet), calls (bets an equal amount with both players then revealing their hands), or drops out (makes no bet and takes no part in the hand). As players raise or call, they move the correct number of counters from the centre pool towards themselves. Once a player has raised, the other must re-raise, call or drop out. Once a player has called or dropped out, then the round is over. Players may only bet or raise the other by one chip.

If a player is called by the other, then the dice are revealed and the player with the losing hand takes all the chips that have been bet (the chips not in the centre pool). The winning player is captain for the next round.

If a player drops out, then he takes a penalty chip and the other chips are moved back to their positions at the start of the hand. The other player becomes captain for the next round.

If both players pass, then no chips are taken by either player and the captain changes for the next round.

The second round is played in the same way except that when throwing the dice players are allowed to put aside any they wish, and throw the remainder with their remaining throws. Players should keep any dice put aside concealed from their opponent. Any dice put aside may be re-thrown with the third and final throw if a player wishes to do so.

The third round is played in the same way as the first.

Once a player has eight chips and only one is left in the centre or with the other player, an open throw is played. The player with only one or no chip has up to three throws of the dice to get the best hand he can. The hand is exposed to the other player, not concealed as before, and if the open throw occurs on the second round he may put aside dice and throw the remainder in his turn as before. The opposing player then throws the dice in the same way. Should he fail to beat the first player's hand, he takes the last chip and loses the game. Should the first player lose, then he takes a chip from the other player and plays on as before.

When three or more are playing, each player starts with six chips and none are placed in the centre. The captain is decided as before with each player rolling a die and the highest taking the captaincy. The winner of a round then becomes captain for the next. Should all players pass, then the player to the left of the captain becomes the next captain.

As before, each player in turn rolls their dice in an effort to get the best possible hand which they conceal from the others. If all the players have taken the same number of throws, then the captain is unchanged. If not, the player who has taken the fewest and is nearest in turn to the original captain becomes captain. The betting limit, however, is three chips and players may only raise by a maximum of two chips. As betting proceeds, each player places their chips in the centre to form a pool.

Montevideo is played using Bidou combinations but with the same betting principles as the card game poker. Three or more players may take part. Each player starts with six chips and the winner is the one who eventually takes them all. Players ante one chip into the pool before throwing the dice at the start of each round. Betting then continues as in poker with players raising, calling, dropping out and with the player holding the highest ranking hand taking the pool.
