Fillblox - Play Online

Block puzzle. Pure logic. Fillblox is a grid-filling brain game where you drag shapes into empty cells. No flips. No rotations. Just spatial thinking. Made by Flagwin Studio, this one's all about pattern recognition and zero mistakes.

How to Play Fillblox

Your mission? Fill every cell. Drag blocks from the right panel onto the grid. Position them to cover empty spaces. Leave nothing blank. That's the win condition. Fillblox starts small—3×3 grids with simple L-shapes. By Level 6, you're managing 4×4 boards with complex Tetromino-style pieces. Adaptive difficulty kicks in. Crush levels too fast? The game throws curveballs.

The Drag-and-Drop Loop

Grab a shape from the inventory. Drag it to the grid. Drop it over empty cells. Each piece locks into place—cannot be rotated or flipped. Wrong spot? Hit Undo. Total mess? Slam Reset and start fresh. Watch the sidebar. Shapes disappear once placed. Plan ahead or you'll run out of moves.

Progression & Difficulty Spikes

Every level cleared = bigger board. More pieces. Tighter gaps. The adaptive system monitors your speed. Beat three levels in under 60 seconds? Expect a grid that punishes trial-and-error. Stuck on a layout? Use the Hint button. It auto-places one piece in the correct spot. Cost? Watch an ad. Level counter tracks your progress. No save states. No checkpoints. Linear climb only.

Pro Strategy

Start with corner pieces. They lock down edges fast. Ignore the obvious placements. Look for the awkward shape first—the one with the fewest valid spots. Place that one early. Scan the grid in quadrants. Top-left, top-right, bottom sections. Treat each zone like a mini-puzzle. Use Undo liberally. Zero penalty. The game wants you experimenting. Running low on options? Watch the ad for a free Hint. Better than rage-quitting.
