The game of Ashta Chamma/ Chowka Bhara is known by many names and is one of the oldest board games extant, still being played in certain parts of India. Similar to Ludo, it is a fascinating game of chance and skill.
Four players each have four pawns, starting at different positions at the four crossed squares at the outermost ring.
The game is controlled by throwing four Kowri shells and counting how many are 'as it is' versus those that land 'inverted': if all four shells land inverted it is called "chamma" and if all land as it is then it is called an "ashta".
Each player takes a turn to roll the Kowri shells. The mouth of the shell landing upwards has a value of 1 and downwards has a value of 0. However, if every shell shows a value of 0, then the value of the roll is 4 and if all of them shows a value of 1, then the value of the roll is 8.
Therefore, the possible values are 1, 2, 3, 4 and 8. Casting 4 or 8 gives the player an additional turn, which can continue until that player rolls a number other than 4 or 8 (namely 1, 2, or 3).
Depending on the number rolled, the player can move one of their pawns that many number of squares on the board. Each player has a fixed path to move pawns, which is in an anti-clockwise direction.
Each player's piece must completely traverse the outer squares before moving into the inner squares.
The tokens enter the board only after a Chamma or Ashta is thrown. Since each cowrie carry 2 points, 2 tokens for Chamma and 4 tokens for Ashta are entered on the board. The tokens travel anti-clockwise in outer squares, clockwise in inner squares and finally lands up in central square (home), with a throw of Ashta or Chamma. If a player's token lands on a square occupied by opponent's token, then the opponent's token is "killed" and the player gets an extra turn to play. The killed token returns to its starting home square and has to go round all over again. In crossed boxes, killing is not possible. When a token reaches the square left of its home square, it further moves up into the inner squares and now moves in clockwise direction. However the tokens enter the inner squares, only when at least one of the opponent's tokens are killed. Otherwise they keep circling around until at least one of the tokens of opponent is killed by them. Every token need not kill an opponent. Each token finishes its race when it manages to get into the home. The first player to get all his tokens into home wins the game.
Whenever a Chamma or an Ashta (4 or 8) is obtained during a throw of cowry shells, the player gets a bonus turn to throw the cowries. When a player cuts an opponent's token, he gets an extra turn to play. During an extra turn, either the same token or some other token can be played. If a player throws either a Chamma or an Ashta three times consecutively during his turn, he is out, and cannot use any of the moves. If a player has cut once, all the coins can move into the inner circle, not necessary for every coin to cut opponent. When most of the tokens are dead, it is possible to bring back the dead tokens. For Ashta, 2 tokens and for Chamma 1 token can be brought back.
Kowries and their values:
- 3 as it is, 1 inverted - Move 1 square
- 2 as it is, 2 inverted - Move 2 squares
- 3 inverted, 1 as it is - Move 3 squares
- 4 inverted Chamma - Move 4 squares
- 4 as it is Ashta - Move 8 squares
For a player to win, he/she must move all their pawns to the center square.
