Animal Chess Rules - How to Play Jungle
Learn the Animal Chess rules used here: the 7×9 board, animal ranks, rivers, jumps, traps, dens, and game-ending conditions.
Board, animals, and objective
Animal Chess uses a 7×9 board. Each side has one rat, cat, dog, wolf, leopard, tiger, lion, and elephant, ranked 1 through 8 in that order. Players alternate moving one animal. Entering the opposing den wins immediately, while entering your own den is illegal. This engine also awards a win to the other player when the player to move has no legal move, and a draw after 60 consecutive half-moves without a capture. Material helps, but a clear route to the enemy den and a legal move for your next turn matter more than a simple piece count.
Movement and ordinary captures
An animal normally moves one square up, down, left, or right. Diagonal movement is not allowed, and a move cannot leave the board or land on a friendly animal. An adjacent enemy may be captured when its rank is equal to or lower than the moving animal’s rank. Thus a wolf can capture a cat and an elephant can capture a wolf. Rank does not make a piece move farther; every ordinary move is still one orthogonal square. The special terrain rules below can change whether a nearby enemy is actually capturable.
Rat, elephant, and water
The rat is rank 1 but has a unique exception: it may capture the rank-8 elephant, while the elephant may not capture the rat. It is also the only animal that may enter water. The middle of this board has two separate 3×2 river areas. A rat in water cannot capture an animal on land, and an animal on land cannot capture a rat in water. This matters at the bank: crossing the river is useful, but water does not let the rat take a land defender or let that defender take the rat.
Tiger and lion river jumps
Tigers and lions cannot enter water. When the next square in a straight orthogonal direction is water, however, they may jump over the entire connected river stretch and land on the first land square beyond it. That landing square may be empty or may hold a capturable enemy. The jump fails if any rat occupies any water square on its path. A rat in a river therefore blocks a lion or tiger even when it could not beat that animal in an ordinary land capture. Away from a river, both animals use the same one-square movement as the other land animals.
Traps, dens, and the finish
There are three traps beside each den. An opposing animal on one of your traps has effective rank 0, so any of your animals may capture it, regardless of its printed rank. A trap does not weaken your own animal; it weakens only an enemy intruder. This makes a small defender near the den valuable and makes a powerful attacker vulnerable if it steps carelessly into a trap. You do not need to capture every enemy animal to win: enter the opposing den, or leave the opponent with no legal move. Avoid long captureless drifting because the engine draws after 60 half-moves without a capture.

Practice the rules on the board
Before every move, check the square, river boundary, trap owner, and every possible rat-blocked jump.
