My girls remembered about it just lately and have had somewhat of a frenzy of practice sessions with it. It's simple, free, yet fun. So I decided to give you, my readers, a quick review of it.
You "shoot" meteorites that are falling down by answering math problems (type the problem's answer and press Enter/Return). If you can't answer one, the meteorite does some damage to one of the penguin's igloo. Then after enough damage, the penguin in that igloo leaves (walks away).
But, once you answer a red "fiery" question that falls down real quick, you can get a cloud that comes and fixes the igloo. Then your penguin comes back! I think that's so cute!! You can only lose if all your penguins go away.

The options include any of the four operations, or have them mixed. You can practice specific times tables for example, which is good for my younger daughter at this time. As you go along in a game, then the questions start coming down quicker. At first they come down quite slow.
There's a training section, and there's a section where it gives you random questions. In that one, you play as long as you want, and when you stop, it'll tell you if you are in the top ten highest scores for you. If so, then you go in the "hall of fame."
Once you finish any particular type of problems (for ex. addition 0-5 or multiplication by 4), the star for that turns glowing yellow, and that's what my kids are after--they want to turn all those stars yellow. That's only in the training part, though. In the training part you have to answer a certain amount of questions.
You can make as many new "accounts" as you want and fill the "hall of fame" with you and your various nicknames.
It's just simple free game for math practice; there are no special features such as reports or training the facts you answer wrong.
Tux Math, or Tux of Math Command is software that is available as a free download for Windows, Mac, and Linux. Download it here.
