Lava is a territorial stacking game for two players, Red and Black. Play using a Hexhex board of edge size 4, and a sufficient supply of Red/Black stacking checkers. To setup, place one Red and one Black checker in opposite corners of the hex hex board.
On each turn, take N checkers (where N is any number from 1 to stack size) from the top of a stack you control and move them N spaces in a straight line to a destination containing N or less checkers. Then, add a new checker of your color to the destination. Stacks may not jump over enemies, but may land on enemy or friendly stacks, thereby burying them.
When the board is full, the player controlling more stacks wins the game.
Lava was designed by Michael Amundsen and Alek Erickson in August 2021.
