Nano Chess shrinks the world's greatest strategy game to a 6x6 board built for your Apple Watch. Every match is quick, tactical, and surprisingly deep. HOW IT WORKS Two players take turns on the same Watch. Tap a piece to select it, tap a valid square to move. It's that simple. REAL CHESS RULES, COMPACT BOARD Six piece types: King, Queen, Rook, Bishop, Knight, and Pawn — each with authentic movement. Full check and checkmate detection. You cannot move into check, and pinned pieces stay pinned. Stalemate recognition for fair draws. Pawns auto-promote to Queen when they reach the far rank. DESIGNED FOR THE WRIST Clean 6x6 grid with large, tappable squares that work on every Apple Watch size. High-contrast filled pieces — white vs. black — readable at a glance. Haptic feedback on every move: a tap for success, a buzz for invalid attempts. Visual highlights: green for selection, dots for legal moves, red for captures, and a red king square when in check. FAST & FOCUSED No timers, no accounts, no internet required. Just open the app and play. A typical game lasts 2–5 minutes — perfect for a quick break, a commute, or settling a bet. PERFECT FOR Chess fans who want a faster format Friends looking for a quick wrist-to-wrist challenge Beginners learning piece movement and tactics Anyone who loves strategy games on the go Nano Chess. Big tactics. Tiny board.
