Pick a shape and start placing tiles. Bring one near another and it pulls into place with a satisfying click — edge to edge, perfectly aligned, every time. There's no wrong way to put them together.
The board never runs out. Zoom in and your tiles are stitched patchwork; zoom out and the whole thing becomes a mosaic. Build something small and neat, or keep going until it fills the screen and then some.
Each puzzle uses one shape, so every piece always fits.
Cycle through color schemes as you build, or open the color wheel — shaped like whichever tile you're using — and pick any shade you like. Painted the wrong one? Recolor tiles you've already placed.
No timers. No scores. No levels to fail. Nothing chases you and nothing runs out. Left click and right click do exactly the same thing, so younger builders never have to remember which is which — and undo is always one key away.
Every puzzle saves as you go. Come back later and pick up exactly where you left off, or keep as many separate builds as you like.
Simple enough for small hands, calm enough to lose an hour in at any age.
