About the game
Suguru Blocks is a number puzzle with two simple rules. The grid is split into outlined blocks of one to five cells. A block of three cells holds 1, 2 and 3, a block of five holds 1 to 5, and so on. And the same number may never appear in two touching cells, side by side or corner to corner.
The twist is the neighbour halo. Select any cell and its eight neighbours and its whole block light up, so you can see at a glance which numbers it's allowed to take, and any clash turns red the moment you place it. Thirty puzzles grow from 5x5 to 8x8. Every one has exactly one answer and can be solved by logic alone. Later boards need a sneakier step, where a number trapped in one corner of a block blocks the cells around it.
