Choose their piece, they yours

$1.99 · In‑App Purchases · Designed for iPad. Not verified for macOS.

Quarto is one of the most elegant strategy games ever designed. Simple to learn, endlessly deep. 16 unique pieces. 4 attributes. 1 winner. Each piece is defined by four binary attributes — size, color, shape, and fill. On your turn, you choose a piece for your opponent to place. The catch: you might just be handing them the winning move.

This app is a loving port of an original 1999 school project implementation, rebuilt for modern iOS with all the depth the game deserves.
