Fill The Blocks

Fill The Blocks is a simple, satisfying puzzle about covering every empty square on the grid with colorful cubes. Each stage asks you to find the right order of moves, and the layouts get trickier as you go.

How to Play

Use the mouse to swipe in a direction. Your cubes slide along that path and fill the empty squares they pass. Choose your directions carefully so that every blank space is filled by the end. If you leave a gap you cannot reach, try the stage again with a different route.

Tips

• Look for dead ends and plan to fill them first.
• Think a few moves ahead before your first swipe.
• Restart early if a route clearly will not work.
