Tower Protect 3D! vs Tic Tac Stack

Save the tower by choosing right blocks to pull

Tic-tac-toe just got a brain upgrade. In Tic Tac Stack, bigger pieces gobble smaller ones. Stack your way to three in a row — but watch out, your opponent can steal any square by dropping a larger piece on top. Every move hides a secret. Every win feels earned. Stack pieces from three sizes. Play smart. Outsmart the AI or challenge a friend. HOW IT WORKS Place a piece on any empty square. Or gobble your opponent's piece by covering it with a bigger one. But be careful — you can gobble your own pieces too. The board shifts with every move. What looked like a win can disappear in one play. WHAT MAKES IT DIFFERENT Classic tic-tac-toe always ends in a draw. Tic Tac Stack never does. With three piece sizes, hidden stacks, and shifting board states, every match plays out differently.
