Collect Stamps

Every stamp is hidden behind a puzzle called a "nonogram." Use the hints along the left and top to reveal the picture on the stamp. There's multiple books to be filled, so solve as many as you can!

For New Players and Longtime Fans

If you've never solved a nonogram in your life, have no fear. There are many tools available designed to help you along while solving the puzzle, as well as a tutorial to help ease you in. If you're a long time puzzler, you can turn them off and let your logic skills loose!

Gameplay Features

• No time limit or rankings. Take as long as you like to solve puzzles.

• No Guesswork! All puzzles can be solved using logic alone, and don't require any guessing.

• Blue hints help show you where you can logically work out a move, while Red hints help show you where you've made a move that doesn't fit in. Or, turn off hint suggestions entirely!

• Many support options to help move you along when you're stuck, like showing all mistakes in a puzzle, revealing the correct solution on a chosen line, and visualizing possibilities based on the hints of the line of your choosing. Use these features as much as you like, or don't use them at all! There is no penalty for using these features.

• Save puzzle at any time and come back to it later. You can save as many as you like (but you should solve them at some point.)

• Choose between having the game automatically mark off hints for you, or marking off hints yourself.

• Additional features such as undo/redo, placeholder markers, counting the number of marks in a line, and more!

• Skip any puzzle you don't like! You'll only need to solve a certain amount of puzzles to progress.

Optional Challenges

• Want to really test your skills? The optional "Timed Mode" will give you a certain amount of time to finish the puzzle, and deduct time for mistakes made.

• Achievements for how many puzzles you solve, as well as certain other actions taken in-game.

Additional Features

• Keyboard and mouse support, as well as support for many popular gamepads.

• Create your own puzzles¹, or play puzzles that the community has made!
