This game is played on the following board.
- STACK - A stack of 1+ stones of either color.
- The color of the stack's top stone determines its owner (e.g., a black top stone makes it a black stack).
- TURN - On each turn, each player must do one of the following actions:
- Drop a single stone at any empty cell, or
- Capture an enemy stack by moving two friendly stacks on top of it.
- Stacks can slide over a straight line of empty cells (no jumps).
- Stacks cannot have more than 5 stones.
- Stacks cannot split.
- GOAL - Wins the player owning three stacks of size 5.
These rules imply that stacks of size 5 are not capturable and cannot capture (and thus cannot move). Also, stacks of even size (size 2 or 4) cannot appear during a match. As a logical consequence of the other rules, the resulting stack always have a majority of friendly stones (2 vs 1 or 3 vs 2).
A capture example
He can capture the black stack by sliding two of its owns stacks at moving range. The result is a stack of size 5.
This game is the last game of Dieter's "Stacking Game Trilogy" which includes Abande and Accasta. Check Attangle's official rules.
One comment from Dieter: Attangle is not necessarily a stacking game. You can imagine a Mancala-style board (with buckets) where you place unstacked stones. It's the majority that counts, not the "top stone". This again is a subtle part of this game I like, it has a certain mutable nature.
