Line is a free Android game developed by 2121 Dev. It is a minimalistic game that challenges your reflexes, tests your speed, and puts your patience on trial. The objective of the game is to guide a line through an endless, sinuous, and unpredictable path. The rules are simple, tap once to go down, tap again to go up, and try not to let the line hit the borders.

The game may seem easy at first, but it is quite challenging to make the line move exactly as you want. To succeed, you need to accept that it will be nearly impossible to avoid hitting the borders. The game is addictive, and you will find yourself trying to beat your high score.
