WarpGrid – Swap Sort Puzzle

WarpGrid presents a 4×4 grid of numbered tiles scrambled into a random order. Dashed warp lines connect specific pairs of tiles across the grid — these are the only swaps available to you. Tap a tile to select it and it glows amber. Any tile connected to it by a warp line lights up blue to show your options. Tap a blue tile and the two swap positions. Tiles that are already in their correct position glow green so you can track your progress at a glance. The puzzle is solved when every tile reads one through sixteen in order from top-left to bottom-right. The challenge is routing numbers to their correct positions using only the available warp connections — some tiles have many connections while others have just one or two, forcing you to think several swaps ahead. Fewer total swaps earns a higher score. Warp networks become sparser and more irregular as levels progress.
