Partition — v0.8a Singleton Test
2-player abstract strategy game · 3 actions per turn · score through closures and final regions
Beginner makes straightforward tactical choices. Medium plays a stronger positional game. Advanced uses the strongest tested strategy.
How to Play — v0.8 + Singleton Experiment
Goal: Finish with more points than your opponent. Each player has 10 small marker cubes: Player 1 uses white and Player 2 uses black. The site handles setup, legal moves, marker placement, region closing, and scoring automatically.
- Take 3 actions on your turn. You may repeat an action if it is legal.
- Place Stick: choose Place Stick, then click an edge between adjacent hexes in the open region. The smaller side closes. If a non-final split is equal, you choose which side closes.
- Singleton restriction (experiment): a normal stick may not create a 1-hex closed region while any other normal stick placement can avoid creating a singleton. If every available normal stick placement would create a singleton, singleton closures become legal. The final 1-1 equal split is always legal. Subdivision may still create a singleton.
- Claim Colour: each player may claim up to 2 colours. Choose Claim Colour, then click a disc in any closed region. That disc is removed and its colour becomes yours. Place your marker cubes on every remaining disc of that colour: Player 1 uses white cubes and Player 2 uses black cubes. The coloured disc remains visible beneath the cube.
- Subdivision: each player has 2 uses. Choose Subdivision, then place a stick inside a closed region. Both resulting parts stay closed.
Closing point: A normal closure scores 1 point if the newly closed region contains discs of at least 3 different colours. Count the disc colours underneath any white/black marker cubes; claimed status does not matter. Subdivision never awards this point.
Game end: The game ends immediately when the remaining open region is split into two equal regions of 5 or fewer hexes each. Both close, and each is checked separately for a closing point.
Final scoring: Every closed region is worth 1 point to the player with more remaining discs matching their claimed colours in that region. A tie scores neither player. One-hex regions score normally.
Important: Once a region is closed, normal sticks cannot be placed inside it. Only Subdivision can modify a closed region.
Both seats use Bot v11 under the v10b closing rule: a newly closed region scores 1 point when it contains at least 3 different colours, regardless of claimed status. Bot v11 also recognizes planned 3-hex double-dip closures that score immediately and are projected to score again at final scoring. This mirror match tests what happens when both players actively hunt those opportunities.
