Rules
Arimaa, pronounced "ah-REE-ma," is a modern strategy game that simulates a sport similar to Rugby or Football (American style), but without the ball.

Goal
Instead of getting a ball to the end zone, the team tries to help their smallest player reach the end zone. The other team is also trying to do the same thing at the same time. The first team to get their smallest player to the end zone wins the game. As the coach of the team, you are the mastermind behind the team's strategy, and must guide them to victory.

Field and players
The game is played on a field divided into an 8x8 grid of 64 squares. The two teams have 16 players each; with one team being gold and the other silver. The players are assigned positions based on their size. Animal names are used for the positions. Each team has 1 elephant, 1 camel, 2 horses, 2 dogs, 2 cats and 8 rabbits; from largest to smallest in size. Any one of the eight rabbit players needs to reach the end zone to win the game.

Setup
The game begins with an empty field. The gold team enters first, and the players stand in any configuration on the first and second ranks. Only one player may stand in a square at a time. The silver team then enters the field, and the players may stand in any configuration on the seventh and eighth ranks. The first and eighth ranks are the end zones.

Movement
The gold team moves first followed by silver. A move consists of 4 steps, where each step is the movement of a player from the current square to an adjacent unoccupied square. In Arimaa, adjacent always means orthogonally adjacent; so a player may step to an adjacent square by moving left, right, forward, and backward. However, the rabbit players cannot step backwards. The team can distribute the four steps any way it wants. One player can take all four steps, or the four steps can be distributed among various different players. A player taking more than one step may change directions after each step. The team does not need to use all 4 steps, as long as at least one step is taken to change the state of the game.

Pushing and pulling
Players can push or pull smaller players from the opposing team. They cannot, however, push or pull opposing players that are larger or equal in size. A push or pull requires two steps and must be completed within the same turn. A larger player can push the smaller player to an adjacent unoccupied square and move into the vacated square. A larger player can pull by moving to an adjacent unoccupied square and dragging the smaller player into the vacated square. A player cannot, however, do both a push and pull simultaneously.

Freezing
Players that are adjacent to larger players from the opposing team are held frozen and cannot move. However, if a teammate is adjacent to the frozen player, the player is no longer frozen and can move.

Capturing
There are four muddy spots on the field called traps. They are located at c3, f3, c6 and f6. Players may stand on or cross through the traps so long as a teammate is adjacent to the trap. A player that is on a trap and has no teammate adjacent for support will slip and fall into the mud and has to sit out for the rest of the game.

Other ways to win
A team that has lost all the rabbit players loses the game (by elimination). A team that cannot make a move at all also loses the game (by immobilization).
