Gameplay

To start, Red covers any space.

From then on, starting with Blue, players take turns.

Your Turn

On your turn, you must form the smallest tower possible. You do this by placing a piece on an empty space or one of your towers. If this forms a tower of height 2 or more, pieces may be removed as described below.

• Example: If you can play on an empty space you must do that.
• Example: If you cannot play on an empty space, but you have towers of size 1, 1, and 2, you must play on one of the size 1 towers.

Exclusion Zones

Each tower is surrounded by an exclusion zone with a radius equal to the tower's height.

• Example: A tower of height 1 has an exclusion zone containing 6 hexes.
• Example: A tower of height 2 has an exclusion zone containing 18 hexes.

You cannot place pieces within an exclusion zone.

When a tower grows to height 2 or more, its exclusion zone grows. All towers within that zone belonging to either player are immediately removed.

End of Game

The game ends when only one player has pieces left on the board (except at the end of Red's first turn). The player with pieces remaining is the winner.

Note that a tie is impossible.
