Tangle

Fit and fuse flat shapes to fill the silhouette exactly — but some pieces can't be flipped, so think before you place.

How to play

You are given a silhouette — a set of grid cells — and a collection of flat polyomino pieces. Place the pieces so every cell of the outline is covered exactly once, with no overlaps and nothing spilling outside. Some pieces can't be flipped, and two free pieces can be fused into one compound shape for the level, so orientation and grouping matter as much as fit.

• Cover every silhouette cell exactly once
• Don't overlap pieces or spill outside the outline
• Respect pieces that can't be flipped
• Fuse two pieces when the level calls for it

Controls

• Desktop: click to place pieces on the board; keyboard shortcuts help rotate and position
• Phone & tablet: tap to place and arrange pieces — fully touch-driven

Game modes

• Daily: the same silhouette for everyone each day
• Practice: a fresh shape every run
• Easy, Medium and Hard add larger outlines and more pieces

Tips & strategy

• Start with the most awkward corner — it has the fewest valid pieces
• Place pieces that can't be flipped early, while you still have room to orient them
• Count cells: if a leftover gap can't match any remaining piece, backtrack

What you'll learn

Tangle is about decomposing a silhouette into shapes that fit it perfectly, building spatial and geometric reasoning.

• Skills: spatial reasoning, shape decomposition, geometry
• Best for: roughly grades 3–10 (ages 8–16)
• For parents & teachers: spatial problem-solving with shapes.
