Which puzzle should I choose?
Want to understand a move? Start with Nonograms: its explanations show why a cell can be filled or crossed out. The illustrated rules introduce the clues. Or learn Binairo with worked 0-and-1 examples.
Enjoy thinking several moves ahead? Try Sokoban for box placement or Knight’s Tour for route choices. Both let you undo moves. See the illustrated Knight’s Tour strategy and 5×5 solution.
Prefer changing the whole board? Try Lights Out. A press affects neighbouring cells, and the worked light-chasing example shows how to work through the rows.
Before you play
Do I need an account or a download?
No. Open a game page and play in your browser, on a phone, tablet or computer. The collection is free to play and currently has no ads.
Do all games explain their hints?
No. Nonograms explains supported deductions. Other games offer different kinds of help, such as undo or a suggested move. Sudoku hints place a solution digit without explaining the deduction.
Can every puzzle be solved without guessing?
Not every generated board guarantees that. Minesweeper may need guesses later, although the first click and its neighbours are safe. Sudoku difficulty settings are not a rating of the logical techniques required.
