Euclidea

It’s easy to categorize Euclidea as a game, but that it’s more than just that. This is not about getting the high score or about reaching a conclusion to a story; it’s about completing the challenges that are put forth by the applications.
Much of the geometry that we’re learning today is Euclidian, which means that people won’t find the game all that difficult, at first. On the other hand, when you advance in Euclidea you will find that you’re not only finishing levels, you’re also learning along the way.
Players will only be able to use a straightedge and compass, and it has to be done with the least number of moves possible. You don’t have to be a math wizard to play this game, but it won’t hurt either.
