Solve it to see it: picture letters.
Nonopost is a nonogram (picture logic) puzzle game. Every day there is one new puzzle that is the same for everyone in the world. You can also draw your own pixel picture, turn it into a nonogram, and send it to a friend as a link. Your friend sees the picture and your short message only after solving it.
Each day brings a new puzzle, identical worldwide, and every puzzle has exactly one solution.
Draw on a 10×10 or 15×15 grid and add a message of up to 40 characters. The app checks that your picture can be solved and adds starting clues if needed.
A letter link contains only the picture, the message, the letter paper, and an optional display name. Nothing is stored on our servers, and no account is needed. Friends without the app can solve it in their browser.
Hints and undo can be used with ink (in-game currency) or by watching a rewarded ad. Premium removes ads and unlocks past daily puzzles, unlimited hints, all letter papers, and 20×20 drawing.
