• You get 3 actions per turn — spend them on the same stack or split across stacks.
• Each action: move a stack to an empty adjacent tile, or stack it onto your own adjacent stack (heights add).
• Moving onto an enemy or neutral camp stack attacks it: damage = the smaller of the two heights. Both sides lose that much — the bigger stack always wins and survives with the difference, equal stacks wipe each other out. Exception: a lone 1-cube stack that lands the kill takes no retaliation damage.
• After every action, your homebase pushes a new cube out along each open direction, shifting any queued-up cubes forward to make room. If the line can't go further straight, the new cube stacks onto the front instead.
• Capturing one of the 7 gold-ringed neutral camps claims it permanently (no need to keep a stack standing on it) and immediately grants +1 cube on the capturing stack plus a bonus homebase spawn. While held, it keeps producing +1 cube on itself and a homebase spawn every one of your turns.
• Stacks taller than 3 can jump: instead of only moving to an adjacent tile, they can leap straight to any other friendly stack connected by a walkable path, however far away.
• Capture the enemy homebase tile to win.
