Store listing
By Robin s.p., from Google Play“Draw one continuous stroke. Cross every line exactly once.”
Description by Robin s.p. Written by the developer, not by AppBrain. Click to read.
ONCE is a minimalist logic puzzle about finding a route through a geometric board. Draw across every line exactly once, keeping your stroke clear of the points. A simple triangle can teach you the idea. A more intricate shape can make you stop and look again.
PLAN YOUR PATH
Your stroke crosses the puzzle's lines. Each crossing lights up the board and brings you closer to a complete solution. Cross a finished line again, touch a point or slide along a line, and the attempt ends. Keep drawing until every line has been crossed.
FIND YOUR FLOW
Work through 1,000 campaign puzzles, from spare geometric forms to layered patterns that take a little more thought. Learn the rules in a playable tutorial, then find a route of your own.
MAKE A LITTLE SPACE TO THINK
Clean shapes, clear feedback and a choice of dark or light theme keep the board easy to read. Adjust sounds and vibration to suit the way you play. Daily challenges offer another puzzle to work through, with monthly trophies to mark your progress.
One stroke. Every crossing counts.
