## What is Quarto?

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.

GAME MODES
- Human vs AI — four difficulty levels from beginner to expert
- Pass & Play — challenge a friend on the same device
- AI vs AI — watch two AIs battle it out
- Online Multiplayer — play friends via Game Center

FEATURES
- Beautiful piece rendering with transparent hollow tops
- Drag or tap to place pieces
- Threat visualization — see danger before it's too late
- Undo and move history
- Win detection across all 19 winning lines including 
  2×2 squares — the surprise win most players miss
- Confetti celebration on every win
- Interactive tutorial for new players
- Full How to Play guide with animated examples

PREMIUM (one-time purchase)
- 4 premium themes: Neon, Crystal, Marble & Metal
- Game Replay — watch any completed game move by move
- Statistics Dashboard — track your wins, streaks & records

Quarto was invented by Blaise Müller. This app is a loving

iOS with all the depth the game deserves.

### 5/5 — Excellent Implementation!

*2026-06-12*

I was kind of expecting 3D pieces and board, but this is a great implementation using about every feature available to Apple gamers with AI! Nice job!
