Editor review
Swap Grid is a bottom-of-the-barrel sliding puzzle. The classic 15-puzzle reskinned with no enhancements. Slide numbered tiles into the empty cell to sort 1-15 in order. The format is over a century old and Swap Grid does the minimum to deserve a place on this catalogue.
What does not work is the implementation quality. Sliding animations are slow. Tile drag-and-drop is laggy, and the visual presentation is generic. The classic 15-puzzle is one of the most-implemented puzzles in computing history; there is no excuse for a 2026 implementation to feel less responsive than free Java applets from 1998.
The game offers three difficulty modes from 3x3 up to 5x5. The 5x5 mode is the only thing keeping this from a lower rating because most implementations stop at 4x4. The 5x5 puzzles are seriously difficult and might satisfy committed solvers, if the rest of the experience were not actively annoying.
Tested over two morning commute sessions and gave up. Touch input lag makes the format frustrating. Mouse-drag is slightly better but still noticeably slow. Keyboard input is supported and is the only acceptable input on this implementation.
Where I would push back is the entire monetisation layer. The game shows ads after every solve. There is a paid 'hint' system that reveals the solution to the current state, plus a paid 'skip' feature on top of that. The 15-puzzle should not need any of this.
Two stars. The game functions but is harmed by poor implementation and aggressive monetisation. Skip and use any other 15-puzzle implementation. Most browser-based sliding-puzzle clones are better than this paid-feature pile.
