Nintendo's hugely successful maths DS game, Big Brain Academy, is on it's way to Wii and, as you can see, it's got all the puzzles you'll need to work that mental matter.
Big Brain Academy: Wii Degree will test your memory, logic and number-crunching skills and rate you at the end. If you're a thickie it will tell you how to improve using simple mind exercises, and seeing your stats improve is what makes this game so addictive.
Nintendo is keen to show it off - they unleashed 127 screenshots of it. But we thought that a tad excessive, so here's the pick of the best ones that show actual mini games in action.
The game is set to hit the US in summer. Hopefully a UK release won't be too far behind.
