Fusion Box

FUSION BOX is an arcade-style merge puzzle: drop balls into the box and combine two identical ones to evolve them into the next tier. Plan your drops, trigger chain fusions for big combos, and watch the box fill up as the balls grow. Unlock 5 themed arenas — from toys to a fiery inferno — each with its own music and hazards, plus 15 collectible ball skins. Take on the Daily Challenge, where every player gets the same ball sequence, in an arena that rotates weekly. Easy to pick up, hard to put down: how high can you stack before the box overflows?
