Zippy

Zippy is a deceptively simple path puzzle. Draw a single continuous line that connects the numbers in order — 1, 2, 3, and on — while filling every cell on the grid exactly once. No diagonal moves, no crossing walls, no leaving a square empty. There's exactly one solution to each puzzle. Can you find it?

It's easy to learn and satisfying to master: a few seconds for the gentle warm-ups, a proper think for the head-scratchers. Trace the line with your finger, feel it snap cell to cell, and watch the grid fill in.

Features • Hand-crafted, guaranteed-unique puzzles across Easy, Medium and Hard packs • Smooth, tactile finger-drawing with satisfying, instant feedback • Undo, Clear and a gentle Hint when you're stuck — no penalties, no pressure • A built-in timer and backtrack counter — your best time on every level is saved so you can come back and beat it • Completely offline. No accounts, no sign-ups, no ads, nothing collected — your progress stays on your device

Draw the line. Fill the grid. Zip it.
