Magic coloring
Apply a math rule across the grid, the picture appears at the end.
Each cell has a calculation. Apply the rule, color every cell - the picture reveals itself at the end.
- Step 1: read the rule above the grid.
- Step 2: pick a color, tap or drag across the cells to paint them.
- Step 3: color every cell (white is a real answer), then validate.
