How to Play Solo Chess
Make legal chess moves to capture pieces until only one remains. Every move must be a capture.
Try it now — Easy 5x5 →The Rules
- Every move must capture another piece — no piece may move without taking another
- Pieces move according to standard chess rules
- Win when exactly one piece remains on the board
- If no legal capture exists and pieces remain, the sequence fails — restart and try a different order
Available in 3 sizes (4x4, 5x5, 6x6) and 3 difficulty levels (easy, normal, hard).
See It in Action
Capture pieces until exactly one remains — every single move must be a capture
How to Play
- Count the pieces — you need exactly (N-1) captures to leave one piece remaining
- Identify pieces that can only be captured in one way — plan those captures early before they become unreachable
- Work backward from the desired final piece to find the capture sequence
- Avoid creating isolated pieces no other piece can legally reach
Pro Tips
A piece that cannot be captured (no other piece can legally reach it) must be the final remaining piece
Knights have unusual reach — track which squares they can access from their current position carefully
If a sequence leads to a dead end, try making the last capture first — capture order often matters more than it seems
