Fillblox
Each level is a single board to fill, and you drag shapes from a side panel onto the grid. Pieces cannot be rotated or flipped, so you need to find the one placement that covers every empty cell. It runs in the browser on desktop, phone, or tablet in portrait, with no installation needed.

About this game
An engaging logic puzzle where your goal is to fill the playing field with shapes. You’re given several blocks of different forms — drag each one into place so that not a single cell is left empty. Sounds simple? With every level, the board gets larger and the pieces grow more numerous and more intricate.
An adaptive difficulty system adjusts to your pace — if you’re blazing through levels too quickly, the game will throw a tougher challenge your way. Stuck? Use a hint to automatically place one piece in the right spot.
How to play
Drag a shape from the panel on the right onto the playing field.
Position it so that it covers empty cells.
Fill every cell on the board to complete the level.
Shapes cannot be rotated or flipped — find the correct spot for each one.
