About 4x4 Puzzle Collection
Slide numbered tiles across a 4×4 grid, one move at a time, until every piece sits in its correct position. It sounds simple — and then you realize you've shunted the wrong tile into the corner and have to think three moves ahead to dig yourself out. That satisfying crunch when the last tile snaps into place is genuinely earned.
The collection includes multiple puzzle images and difficulty levels, so there's a real range from approachable warm-ups to sessions that demand serious concentration. If you enjoy this kind of grid-based logic, puzzle games on Launch Arcade have plenty more to keep your brain busy — including 2048, which scratches a similar tile-sliding itch with a number-merging twist.
No timer breathing down your neck here, which makes it a good fit for short breaks or quiet focus sessions — just you, a mouse or finger, and a scrambled grid that won't solve itself.
