Sudoku meets pizza. Place toppings to satisfy every rule — 500+ levels of cozy constraint-puzzle satisfaction.
Slice Stack is a cozy logic puzzle with a pizza twist — think Sudoku or Picross, but you're topping a pie.
Each level gives you a half-pizza board, a handful of toppings, and a set of rules. Tap to place toppings so that every rule is satisfied at once: no two neighbors share a topping, a sector needs exactly so many olives, pineapple has to sit next to ham, and more. Simple to learn, satisfying to crack.
No timers, no pressure — just the quiet click of a puzzle falling into place.
