Shōbu

A passive aggressive shoving match with mirrored reflections.

SET UP

• Place four 4x4 modular boards arranged in a square pattern with space between them.

• Each board has 8 stones (4 stones of each color), for a total of 16 of each color.

• 4 stones are preset on the back line of each board in uniform.

• A piece of rope, or ‘a line in the sand’ separate two boards for each player.

• Boards are paired: each player controls the two boards closest to them.

Number of Players

• 2

Objective

• Push all of your opponent’s stones off any one board to win.

• Stones are never captured; they are pushed off the edge.

Rules

• On your turn, you make two moves:

  1. A passive move: move one of your stones one or two spaces in any direction (orthogonally - adjacently or diagonally) on any board.

  2. An aggressive move: mirrors one of your stones the same number of spaces in the same direction on another board.

• Aggressive moves can push opponent stones if your stone moves into their space, provided there is an empty space behind them.

• You cannot push more than one stone at a time.

• Stones cannot jump over others.

• The game ends when a player pushes all opponent stones off a single board.

Player Variations

• A variation could start with the stones preset in the middle row or each board.

History

• Shōbu is a modern abstract strategy game, designed by Manolis Vranas and published in 2019.

• Inspired by traditional games like Go and Chess but with a minimalist, tactile design.

• Known for its elegant simplicity and deep strategic play, it is perfectly described as ‘ beautifully challenging’.

Game Theory / Game Dynamics

• Hats off to Manolis Vranas for coming up with this modern masterpiece!

• This game exemplifies the simple, but deep strategic thinking, needed to win.

• The challenge of passive aggressive mirrored reflection movements make this game very deep. You need to plan your moves in pairs.

• Here are some suggested strategies to play…

• Control the Center

  • Stones in the center of each board have more flexibility for movement.

  • Central positions give you more options for both passive and aggressive moves.

• Balance Your Boards

  • Don’t focus only on one board—winning requires pushing all opponent stones off any one board, but neglecting others makes you vulnerable.

  • Spread your influence across all four boards.

• Use Passive Moves Wisely

  • Passive moves are defensive: strengthen your positions and prepare for aggressive pushes.

  • Avoid wasting passive moves on isolated stones unless necessary.

• Plan Aggressive Moves

  • Aggressive moves can push opponent stones off the board, but only if there’s space behind them.

  • Look for opportunities where a single push creates a chain reaction of threats.

• Create Pressure

  • Force your opponent into defensive moves by threatening multiple boards at once.

  • If they respond on one board, you can exploit weaknesses on another.

• Avoid Overextension

  • Don’t push too far forward without support—isolated stones are easy to counter.

  • Keep stones connected for flexibility.

• Think Two Moves Ahead

  • Every turn has two moves (passive + aggressive). Plan them as a pair.

  • Use passive moves to set up aggressive pushes in the same direction.

as much as I have making them.
