How to play
You only have one button. Tap it to hop and swing at the ball. Hold it to crouch and charge, then let go for a big jump: dunks, power shots, spikes and body slams. Hold it too long after it is full and you will wobble over.
Keyboard: Space, W or ↑. Two players on one keyboard: Player 1 uses W, Player 2 uses ↑. On a phone or tablet, tap anywhere; with two players, each takes half of the screen. It plays in both landscape and portrait.
Five sports, five courts
Shoot hoops on a street court at sunset, score goals in a rainy night stadium, spike over the net on a sunny beach, shove your rival out of the ring in a sumo hall and bonk them with a rubber ball in the school gym. Mixed Cup switches sport after every point.
Leagues and bosses
Work through five leagues of eight matches each. Every league ends with a boss who changes the game when you get close to winning: a goal that moves, a higher net, an icy ring edge and more. Win the final point and watch it again in slow motion.
Reversal cards
Lose a point and you get to pick a reversal card for the next one: Big Ball, Moon Mode, Ice Floor, Tailwind, Big Head, Sticky Gloves and more. Want all three stars? Win without using a single card.
Fighters, shop and modes
Unlock 12 fighters with their own floppy bodies, from long-legged Beanpole and super-armed Octo to rocket-powered Rocket and feather-light Feather. Spend coins on upgrades, jerseys, ball skins and goal effects, open star chests and chase 36 trophies. Then try Endless Cup, the Daily Match and 12 Trick Shots.
