For Hexxagon, you play as the red diamonds and your opponent (either another player or the computer) plays as the blue globules. Your goal is to take over all the spaces on the board, and you do this by leaping into the spaces next to your opponent’s pieces.
When you select one of your pieces, highlights of possible moves will be shown. The green highlights show where your piece will duplicate, the yellow highlights show where you will only jump. It’s a good idea to duplicate as much as you can early on, and to spread around the board so you’re not cornered.
