Zip — one line, every box, in order
Zip is now live — a single-stroke path puzzle inspired by the one you might know from LinkedIn, rebuilt for kids 4–8.
How it works:
- Put a finger on the 1 and drag. The line flows behind your finger and floods each box with colour as you go.
- Pass the numbered dots in order — 1, then 2, then 3 — and fill every box exactly once. That's the whole puzzle.
- Drag back over your own line to rub it out and rethink. No buttons, no menus — the grid is the toy.
The deliberate design choice: no timer. Zip is about looking ahead — "where can I go without trapping myself?" — and a countdown would turn patient planning into a race. Win by solving; there's nothing to lose.
Grids start at a gentle 4×4 with three dots and grow on their own — 5×5, 6×6, up to 8×8 with eight dots — generated fresh every time, so the climb never runs out. Progress saves locally: close the tab, come back tomorrow, same level.
Best for ages 4–8. Builds sequential planning and look-ahead — the same spatial-reasoning family as Tangram and Find the Way.
