Hard Suguru
Pick a digit and tap the squares where it goes. With “Notes”, it's noted small; tap again to cross it out, and again to remove it. With a keyboard: arrows to move, digits to write, N for notes.
Hard Suguru gives you 7×9 grids and won't come out just by looking: it needs pairs and triples of cells that share some numbers out. If you get stuck, the hint shows you which one and why.
How to play Suguru
Fill each block with the numbers from 1 up to its number of cells, without repeating any. Two equal numbers can't touch in any direction, not even diagonally, even in different blocks. The numbers already given don't move, and every Suguru has exactly one solution.
The levels
Easy (5×6): you solve it by finding which number each block is missing and where it fits. Medium (6×8): you have to look at which outside cells a number touches before you know where it goes. Hard (7×9): needs pairs and triples. Expert (8×10): needs chains and trying the ways to fill a block, several times. Master (10×12): the same on a bigger grid, with some six-cell blocks that hold 1 to 6.
The hint
The hint doesn't just give you the number: it shows you the next step and why, and points to the cells that matter. With the arrows in the note you can read again the ones it already gave you.
