Its a pretty cool game, very simple, it randomly creates simple calculations and then you have to input the result. It supports all the operations and ranges from easy one digit calculation (eg. 7 + 5, 5 * 8 ) to 4 digit operations. In the hardest mode the numbers have you have to do operations like: 7620 + 8421 or 5654 * 1574, which is pretty hard. I was never good at arithmetics so this game is very challenging for me! :D
I don't know if you will find this useful or fun, but I think its pretty cool.
it's right up there with Wii golf :)
Ahaha, Wii looks like a pretty fun console. It doesn't have many First person shooter games though, it must be cool to use the remote control as a gun. :D
The golf game looks very fun and accurate.
