This classic logic game takes a little math and LOTS of thinking. You have hour glasses with different amounts of sand. You need to use them to find another time.

This is one of my all-time faves. Yeah, it's hard and takes time (past the first level), but I love figuring stuff like this out. You just have to match up all the edges.

This is a class logic puzzle. The goal is to place eight queens on a chess board so that no queen can attack another queen.

If you want a good challenge, this one's for you. You have to rotate pieces of this puzzle to connect like colors.

This game take a lot of concentration. The pods open for just a second to show you what's inside... Then, you have to remember and match the color pairs up.

How well do you know your US state capitals? This game gives you three ways to test yourself: choose it, spell it and locate it!

I like this one because it's easier than those nearly impossible "slider" games. With this one, you can deal with one row at a time. I can actually solve this one!

The computer briefly shows you a pattern on the board... Then, it disappears and you have to reproduce it.

You have to find the path for the monkey to get the banana. Mmm bananas. The trick is that the monkey takes a turn every time he can, so you have to plan ahead.

A classic puzzle game where you have a set of weird shapes and you have to put them together to form a given, bigger weird shape.
