Time game is a quite suggestive game but it is also just complete waste of time.
Time game is about sensing time. It is very simple. In the game you get questions about time intervals. You could be asked: "How long is 34 seconds" and now your job is to get as close as possible to the right answer. You push the stopwatch to start and then you let time pass until you think 34 seconds have passed.
The closer you get, the more points you earn. Every time you earn 1000 new points the difficulty level will increase and the time intervals will be larger. There are 10 levels in the game.
You can play on your own or you can play against a friend. If you are two players the level will increase every time one of you reach 1000 points.
