About this game

A calm logic picture puzzle: use the numbers beside the grid to decide which squares are filled and a small illustration appears. 121 pictures from 5 by 5 to 20 by 20, each with exactly one solution that logic alone can reach. Think explains the next step in plain words, Watch & Learn solves pictures with the reasons shown, and a daily picture keeps it fresh. English and Japanese. No timer, no ads.

How to play

1. The numbers beside each row and above each column give the lengths of the runs of filled squares in that line.
2. Tap a square to fill it, or drag along a line to fill a run. Use Cross to mark squares you know are empty.
3. Think finds the next square that logic proves and explains why. Use Zoom and Move on big boards.
4. Every picture earns up to three stars: solved, no Think, no wrong marks.
5. Learn and Watch & Learn teach overlap, edges and gaps step by step.
