Crosshade

From the App Store Source

Crosshade is a nonogram — a picture hidden behind numbers. The numbers in the margin tell you how many cells in each line are inked, and in what runs. Solve every line and a picture appears. No guessing is ever required: each board has exactly one answer, and every one can be reasoned out. MAKE A PUZZLE FROM YOUR OWN PHOTOS Point Crosshade at any picture in your library. It reduces the image to a grid, decides which cells are ink, and then actually checks the result — if the clues would allow more than one answer, it says so and steps down to a size that works. You never get handed an unsolvable board. 51 BOARDS ACROSS EIGHT CHAPTERS From five-cell warm-ups to fifteen-wide pictures. Every shipped puzzle has been verified to have a single solution. DRAW YOUR OWN The editor checks your drawing after every stroke and tells you whether it is playable yet. Share a finished puzzle as a code or a QR image; codes carry a checksum, so a mistyped one is refused rather than opened as the wrong picture. DAILY AND WEEKLY A new board every day, the same one for everyone, generated on your device so it works with no signal. Four quarters a week assemble into a single larger picture. TIME ATTACK Small boards against a shrinking clock. Each solve buys you seconds. A PUZZLE JOURNAL Keep a solve with a photo or a short clip, so you remember the one that took all evening. MADE TO BE COMFORTABLE Screen brightness, sound, haptics, guide lines, cross marks, cell size and a left-handed tool dock — all of them real settings that take effect immediately. Dark mode follows your phone. NO ADS, NO PURCHASES, NO ACCOUNT Coins are earned by playing and spent on hints. There is nothing to buy. There is no sign-up, nothing is uploaded, and the whole game works offline.
