What's inside
Simple rules, endless puzzles
Learn it in seconds, then keep going: there is always another level.
The same puzzle for everyone
Every level is built from its number, so level 42 on your phone is level 42 on anyone's. Compare notes, or times.
Walls and sparse clues
Later levels add walls you can't cross and fewer numbered dots, so you have to plan the whole route.
Three stars
Finish without hints for three stars. Stuck? A hint trims your line back to the last right move.
