Fill In the holes

Fill In the Holes is a grid-based puzzle where numbers tell you exactly how many boxes to color — but figuring out which ones is where the real thinking happens. Each number anchors a small challenge, and the satisfaction of locking in the right configuration is genuinely rewarding.

The early puzzles feel almost meditative. There's a quiet logic to scanning the grid, spotting the obvious moves first, then working inward toward the trickier spots. No timers breathing down your neck, just you and the numbers.

Later configurations demand more careful planning — a wrong fill in one corner can unravel an entire section. The difficulty creeps up gradually enough that you rarely feel blindsided, but the harder grids will definitely make you pause and reconsider.
