The game is played by 3 players on a square grid. Each player controls a tribe of elementals.

Each tribe has one element:

• W : 💧 Water
• F : 🔥 Fire
• P : 🌿 Plant

The tribes follow a cyclic relationship:

• 💧 Water captures 🔥 Fire.
• 🔥 Fire captures 🌿 Plant.
• 🌿 Plant captures 💧 Water.

🗺️ Map

The map is a square grid made of the following cells:

• .: an empty walkable cell.
• #: a wall.
• W, F, P: the camps of the three tribes.

Camps are walkable cells. Walls are not walkable.

All border cells of the grid are walls.

🎬 Actions

Each turn, output at least one command. Commands are separated by semicolons (;).

• id MOVE x y: orders your elemental id to move one step toward the target cell (x, y).
• id WAIT: orders your elemental id to stay in place.
• MSG [text]: displays a global message under your score. It does not target an elemental. The latest message remains visible until it is replaced. If no text is provided, the message is cleared.

You may provide commands for only some of your elementals. Elementals without a command will wait.

If multiple commands target the same elemental in one turn, only the first is applied and the others are ignored.

↪️ Movement

A MOVE x y command gives a target cell. The game moves the elemental by one step toward that target using a shortest path.

Movement is 4-directional only (north, east, south, west); diagonal moves are not allowed.

If multiple shortest paths exist, the first step is chosen using this fixed priority order: north, then east, then south, then west.

If the target cannot be reached, the elemental stays in place.

Elementals can move through camps and through other elementals. Only walls block movement.

⚔️ Captures

After all players' moves have been processed, all captures are resolved simultaneously.

If an elemental shares a cell with one or more elementals of its predator tribe, it is captured.

A captured elemental becomes a prisoner and is moved to the camp of the tribe that captured it.

Each captured elemental gives 1 point to the capturing tribe. Points are permanent, but a player who times out or outputs an invalid command loses the game regardless of the points they have earned.

Multiple elementals can stand on the same cell. A stack is not stronger than a single elemental: one predator is enough to capture all prey elementals on the cell.

If all three tribes are present on the same cell, the three tribes capture each other simultaneously.

Nothing special happens when a prey elemental enters an enemy camp: camps do not capture by themselves. Captures only occur when predator and prey elementals share the same cell.

🔓 Prisoners

A prisoner cannot move.

Prisoners do not participate in captures. They are ignored during capture resolution.

⛔ Game End

The game ends when one of the following happens:

• At least one player has all of their elementals imprisoned after turn resolution.
• 200 turns have passed.
• A player times out or outputs an invalid command.
