Sep 21, 2026, 7:41 PM@collinsworth I love the idea and aesthetics but I’m having trouble wrapping my head around the puzzle. Can you explain the reasoning behind this hint?

Here, you've got a couple of possibilities for where your remaining 1's can go, but colors eliminate one of the options, leaving you with only that one space for a particular combination of the digit 1 with a certain color.
(FWIW you can press the hint button again to show the answer for that space; I worried that might not be obvious enough.)

@jnkrtech If you'd like a little stronger hint:
...
There's already a blue 1, and another 1 that can't be green, because it shares a row with a green tile already. So one of the unplaced 1's must be green.

@collinsworth thank you! This makes sense. I don’t have any experience with sudoku so I may be getting tripped up on the basics

@jnkrtech Nah that rule gets everyone. (If anything, I think it's harder for experienced sudoku players, because you have to un-train your brain to look at the board in the same old single dimension.)
