This collection features puzzles similar to those presented in the “There Is a Way Out” contest, which will take place on February 1, 2026. Choose a puzzle from the list, and its grid will appear on the right. Click the “Start” button to reveal the given numbers and begin solving.
Most of the puzzles in this collection are more difficult than the contest problems, so don’t be discouraged if you can’t solve them all. And if you do manage to solve every puzzle, you should have no trouble winning the contest as well. In that case, take a look at the archive — you’ll find puzzles there that only true champions can solve.
Grid control:
To draw a cut click at the cell edge or move mouse along the line holding the button. You can also connect the centers of cells which belong to the same rectangle with auxiliary line. In this case cut lines will be added automatically.
More details about grid control are at the help page.
