Rules: Red plays first. A player may extend by placing a tile in an
empty spot adjacent (orthogonally or diagonally) to one of their existing
tiles. All enemy tiles adjacent to the new tile will flip color.
A player may jump by moving one of their tiles to an empty space no
more than two away in any direction. Again, all enemy tiles adjacent to the
new tile will flip.
The game is over when the board is full, at which point the player with the
most tiles wins.
Instructions: Click on an empty spot to extend. To jump, click on the tile,
then click on where you want to jump it to.
