Overview

Axiom is a two-player three-dimensional abstract strategy game designed by Michael Seal and published by Seventh Seal in 1988. Players maneuver cubes (called Axioms) and pawns (called Sceptres) on an ever-changing three-dimensional structure. The goal is to move one of your sceptres onto the same cube as an opponent’s sceptre. The game is notable for its unique 3D gameplay where the board itself is constantly restructured.

Components

• 12 Axioms (cubes): 6 per color (2 colors)
• 4 Sceptres (pawns): 2 per color (2 colors)
• Each cube has domed faces and recessed faces that allow cubes and sceptres to interlock

Setup

1. Assemble the 12 cubes and 4 sceptres into a starting symmetrical position.
2. Single-domed cubes are placed on top of double-domed cubes in the initial configuration.
3. Each player takes the 6 cubes and 2 sceptres of their color.
4. Black plays first.

Turn Structure

Players alternate turns. On each turn, a player moves either one of their cubes (Axioms) or one of their sceptres.

Actions

Move a Cube (Axiom)

• Remove a cube from the structure (it cannot be moved if a sceptre of either color is attached to it, or if another cube is on top of it).
• Rotate the cube to any new orientation.
• Reattach it to any cube of either color, as long as the two pieces mate correctly (domed faces fit into recessed faces).
• The resulting structure must remain a single connected group.

Move a Sceptre

• A sceptre can move horizontally, diagonally, or vertically across the cube surfaces.
• A sceptre can only travel over recessed faces and must come to rest in a recessed face.
• A sceptre cannot pass through or over a cube that blocks its path.

Scoring / Victory Conditions

A player wins immediately by moving one of their sceptres onto a cube occupied by an opponent’s sceptre. Specifically, both sceptres must be on the same cube at the same time.

Special Rules & Edge Cases

• Cubes with sceptres are immovable: A cube cannot be moved if any sceptre (yours or your opponent’s) is attached to it.
• Cubes supporting other cubes are immovable: A cube cannot be moved if another cube is resting on top of it.
• Mating requirement: Cubes must be placed so their faces interlock properly (domed into recessed).
• Connected structure: After moving a cube, all remaining pieces must form a single connected structure.
• Sceptre movement is surface-based: Sceptres travel along the surfaces of cubes, not through the air. They can only rest in recessed faces.
• Both sceptres are active: Each player has 2 sceptres and 6 cubes. Either sceptre can be used for the winning move.
• No passing: A player must make a move on their turn.
