Nonograms

Fill in what the numbers say and a picture appears: a calm puzzle for your phone.

How it works. Every row and column has its numbers: the blocks of consecutive filled squares it holds, in order. Tap to fill or cross a square, and drag to do a whole row at once.

No guessing. Every grid has exactly one solution and is solved one line at a time. If you get stuck, the hint points to a square and explains which line forces it.

A collection of pictures. An owl, a lighthouse, a castle… When you finish, the picture fills with colour, tells you what it is and goes into your gallery. And if you want more, Mosaics never run out.

Four modes. Classic with four levels (from 5×5 to 15×15), a Daily challenge with the same picture for everyone each day, Zen with no timer, and Mosaics.

Genuinely calm. No ads, no purchases and no accounts. Your games, stats and achievements stay on your device. Dark, light and high-contrast themes, left-handed controls and a reduce-motion option. In Spanish, Catalan and English.

How to play

Fill in squares to reveal a picture. The numbers next to each row and above each column tell you how many filled squares there are in a row and in what order, with at least one blank square between one block and the next. Tap to fill a square or mark it with a cross, and drag to do several at once.

Tips to get started

• Start with the big numbers: if a block is longer than half the line, the squares in the middle must be filled.
• Cross out squares you know are blank: they show you where the blocks can fit.
• Switch between rows and columns: every square you settle in one gives clues to the other.
