More squares to solve.

Revisit past Mini, Daily and Challenge puzzles at your own pace. Practice runs save on this device and never affect today’s leaderboard or streak.

Choose a date and size below. The archive begins September 3, when all three sizes became available. Earlier Mini and Challenge puzzles repeated weekly; new puzzles join their schedules from September 15.

Practice with a purpose

Try a Mini to get comfortable with fills and marks. Move to Daily when you can follow deductions between rows and columns. Challenge gives you longer clues and more possibilities to rule out.

If you get stuck, ask which squares must be filled in every possible placement of a group. Our guided tutorial shows this in a small example.
