I found something that is not a game in standard meaning, but it is fun and you can play with. This game fall into test yourself category and let you test if your guess about geometric sense is right.

There are couple type of examples: you will point center of circle, find right angle and so on. After each guess you’ve got the feedback and distance from ideal solution.

And after few tries you’ve got your overall score and look up to the high score table with score distribution of all players.

That’s it, nothing more here, but it is fun. You can play it here.
