1Color Logic rules
- The numbers left of a row and above a column say how many squares in a run to paint in that colour, in the order they are listed.
- Numbers of the same colour need at least one empty square between them. Numbers of different colours may touch with no gap.
- Any square no number accounts for stays empty. When every row and column matches its numbers, it is solved.
2Solving tips
- As in an ordinary nonogram, look at the big numbers first. Any square covered whether the run is pushed left or right can be painted in that number's colour.
- In a line where numbers of different colours follow each other, no gap is needed, so the squares settle more easily than usual. If the numbers add up to the line's length, you can paint them all straight in.
- Where the same colour follows itself, there is always an empty square between the runs. Mark that square and other lines start to settle.
- On screen, choose the colour with the colour buttons below. Drag over a square again in the same colour to clear it; drag in a different colour to repaint it.
How to read the numbers in an ordinary nonogram is covered, with pictures, in How to play and tips.
3Color Logic questions
What is Color Logic?
A nonogram (Oekaki Logic) whose numbers are in colour. Each number says how many squares in a run to paint in that colour. When every row and column matches its numbers, a picture in colour appears.
How is it different from ordinary Oekaki Logic?
Numbers of the same colour need at least one empty square between them, but numbers of different colours may touch with no gap. As well as how many squares to paint, you work out which colour to paint them.
How many puzzles are there?
220 puzzles: 51 at 5×5, 75 at 10×10, 70 at 15×15 and 24 at 20×20. They are split by size, and you can start from any size. The first 51 of the 5×5 are free. After that, one ticket opens the next 3 of that size (2 on 15×15, 1 on 20×20), or the Lounge Pass opens them all.
Is there only one answer?
Yes. Every puzzle has been checked: working from the coloured numbers one line at a time leads to one picture, with no guessing.
