The Royal Study is a chess puzzle of spatial logic.
Rearrange five pieces on a 3×3 board so their types match the Objective. Colors do not need to match — only piece types and positions matter.
HOW IT WORKS
• One shared 3×3 board
• Five pieces: King, Queen, Rook, Bishop, Knight
• Classic chess moves — no captures
• Only the Knight can jump
Before you move, predict how many board moves you need. You can rotate or flip the Objective to help visualize. Each rotation and each flip adds 1 to your move count. Finish within your total.
SOLO MODE
Choose a difficulty, set your prediction, then solve the puzzle within the limit. Progress is saved for each difficulty so you can continue later.
2 PLAYERS (LOCAL)
Both players share one device.
1. One player locks a bid
2. The other may challenge with a lower bid, or pass
3. The player who owns the bid must solve the board
Success scores a point. First to 6 wins the match.
