One Line is a puzzle game where your aim is to create a series of figures using a single line – that is, make a shape without lifting your finger from the screen and without backtracking over the same line.
The first figures you've got to complete are relatively simple and need few strokes, but as you beat levels the figures get harder and harder. In total in One Line you'll find more than 400 shapes split up into 20 packs of more than 20 figures each.
If you get stuck on one of the shapes you have no choice but to ask for a clue. These clues cost you stars, which you'll obviously win as you solve puzzles. (Though you can also buy them with real money.)
One Line is an original and fun puzzle game with more than enough levels to keep you entertained for hours. Completing all the game levels will be a proper challenge.
