Dia Block: Unblock Puzzle 2026

Dia Block is a sliding block puzzle with a look of its own. Slide the blocks, clear the way and guide the diamond to the exit.

FOUR WORLDS, ONE TAP APART
• Light: a beam runs through the diamond and shows how far the path is clear
• Jewel Box: gems on dark velvet, with a ring waiting at the exit
• Kintsugi: every move leaves a line of gold, so each solution draws its own picture
• Harbor: a tiny port at sunset, with a ship waiting for your golden container
Switch worlds at any moment, even in the middle of a level.
