What Makes Shogi Lab Stand Out

A shogi app powered by the full-fledged Sunfish4 engine. With clean, highly readable piece designs and calm controls, you can enjoy every move from the opening to the endgame. In addition to playing, you can check evaluation during a match and replay your games for review, so you can go from play to analysis in a single app. Online matches and rankings are now supported, with CPU matches still available offline.

Key Features

• Analyze while playing (In-game): View the evaluation graph and evaluation value during normal play.
• Thinking time visualization (In-game): Shows thinking time per move in the move list; long thinks are highlighted in red (top 5%) / yellow (top 15%).
• Review cues (In-game / Analysis): Moves where the evaluation shifts significantly are highlighted so you can spot review points quickly.
• Game analysis (Analysis): Review past games with replay / step back / step forward.
• Position jump (Analysis): Tap a move to jump instantly to that position.
• Pause & resume (In-game): Save a game mid-match and continue later.
• CPU strength adjustment (In-game): Change difficulty from practice to serious matches.
• Choose side (Start): Play as either Black or White.
• Undo (In-game): Undo the last move and try again.
• Legal move highlights (In-game): Shows available moves to reduce mistakes.
• Haptics & animations (Controls): Polished feel for moves and interactions.
• Online support: Enjoy online matches and rankings, while CPU play and local two-player mode remain offline-compatible.

This Board game offers engaging gameplay and regular updates for mobile players.
