Relax into a beautiful fruit puzzle that is easy to start, fun to master, and clever enough to keep your brain busy. Match three, manage seven tray slots, and clear a layered stack before it traps your next move. Slay the Stack turns colorful fruit art, readable blocking, and spell upgrades into quick casual puzzle runs. Tap only uncovered fruit runes, send them into the tray, and make triples before space runs out. Each clear gives you a new spell choice, so short offline sessions can grow into bigger combos, safer saves, and smarter routes through the stack. Why it feels good: - Beautiful fruit-rune art with crisp feedback. - Layered tile boards with readable blocking. - Classic triple matching with real 7-slot pressure. - Roguelike spell picks after each level. - Undo, shuffle, and hint tools for close calls. - Optional rewarded videos can recharge an empty skill by +3. - Fast casual runs built for one more try. Read the stack, plan the tray, and clear every fruit tile.
