Checkmate Sliding PuzzleW. G. H. Strijbos from the Netherlands has designed several puzzles. One of them is a sliding puzzle. This puzzle combines the idea of the classic 15-16 puzzle of Samual Loyd with a chess theme.
RulesThe solver of the puzzle must find a series of movements of the squares, such that:
- At the end, the black king is mated. This means that the king is both theoretically as practically checkmate.
- At the end, the board is correctly checkered.
- When a tile with a piece moves, it must be a legal move. Kings may never be played at adjacent (orthogonally or vertically) positions.
- Of course, tiles can only be moved one square horizontally or vertically, to the empty position.
- When a king is in check, it must be able to directly move it away from check.
- Parts b2 and c3 are fixed. The minimum solution is 82 moves.
- Parts c3 and d3 are connected and c2 and d2 are connected. The minimum solution is 68 moves.
- Part c3 is fixed, and parts c2 and d2 are connected. The minimum solution is 68 moves.
