Championship is a tournament-style mode where you face a series of 3 AI opponents with increasing difficulty (Easy, Medium, Hard). You choose your slime at the start and play each match to 3 goals. Win all 3 matches to become the champion! Try it in Championship Mode.

Each slime has a mana bar that powers their special ability. Mana costs vary widely between slimes — from as low as 2 mana (Builder wall) to as high as 90 mana (Nature tree, Retro pixel power). Mana regenerates over time, and the regeneration rate depends on the game mode settings. In most modes, staying on your own side of the field gives bonus mana regeneration, rewarding defensive play before going on the attack.

Abilities fall into several categories. Projectiles like Archer arrows and Cowboy revolver fire objects that push the ball. Beams like Ice frost beam and Murder soul drain create continuous effects. Buffs like Runner sprint and Sponge grow enhance your slime temporarily. Field effects like Cosmos black hole and Nature tree alter the playing field. Summons like Twin clone create additional entities. Instant effects like Alien teleport and Basket dunk activate immediately. Each ability has different strategic uses for offense and defense.
