Quantik

A pure abstraction.

On your turn, you will place a piece on an empty space of the board, respecting one single rule: You are not allowed to place a shape in a row, column, or region in which your opponent has a piece of the same shape. The first player to place the fourth different shape in a row, column, or region wins the game. With Quantik, a single rule is enough to challenge your logic and tactics.
