Hi MajorBaka, the numbers next to each row tell us how many consecutive tiles are checked. For example, if the row says “1,4” somewhere in that row, there will be (from left to right) 1 tile checked, then to the right of that, but disconnected to it, a block of 4 consecutive tiles is checked. This similarly applies to columns. Using the size of the grid and the clues given, the aim is to solve the correct layout according to the clues.
I hope you enjoy solving these puzzles!
