Overview

Dobutsu shogi (Let’s Catch the Lion!) is a simplified shogi variant for two players on a 3x4 grid. Each player controls 4 animal pieces with different movement abilities. Win by capturing the opponent’s Lion or advancing your own Lion to the far rank.

Components

Setup

Each player places their 4 pieces on their nearest row (rank 1) and second row (rank 2):

Turn Structure

Players alternate turns. On each turn, a player performs exactly one action.

Actions

  1. Move a piece on the board to an adjacent square according to its movement pattern.
  2. Drop a captured piece from your hand onto any empty square on the board (Chicks cannot be dropped onto the farthest rank).

Piece Movement

Piece Movement
Lion One square in any direction (all 8 squares)
Elephant One square diagonally (4 diagonal squares)
Giraffe One square orthogonally (4 adjacent squares: up, down, left, right)
Chick One square forward only
Hen (promoted Chick) One square in any direction except diagonally backward (6 squares)

Capturing

Move your piece onto a square occupied by an opponent’s piece. The captured piece switches sides and goes into your hand for later dropping. A captured Hen reverts to a Chick.

Promotion

When a Chick reaches the farthest rank, it promotes to a Hen (flipped over).

Scoring / Victory Conditions

Two ways to win:

  1. Capture the opponent’s Lion.
  2. Advance your Lion to the promotion zone (the opponent’s nearest rank), provided doing so does not place your Lion in check.

If the same position occurs three turns in a row, the game is a draw. Perpetual check is also a draw.
