Slabs: Sliding Puzzle

Slide the tiles, put the numbers in order, beat your best time.

Slabs is the classic 15 puzzle with a bold, neo-brutalist look: chunky tiles, thick borders, hard shadows and bright colors. Easy to learn, hard to master, and perfect for a quick break.

HOW TO PLAY Tap or swipe a tile next to the empty space to slide it. Put the numbers in order, with the gap in the last corner. A short interactive tutorial shows you how on your first game.
