The new release for WiiWare this week will challenge your powers of logic and concentration, and really give your grey matter a bit of a work out.

Based on a real-life puzzle of the same name, Lonpos challenges gamers to arrange differently shaped pieces to fit inside a box by moving and rotating them using the Wii Remote so all the pieces are used.

In Normal Mode, the aim is to solve puzzles as fast as you can to win points. Alternatively, you can hone your skills in Continuous Mode where just one false move means you lose. Harsh.

In Cooperative Mode, users get the chance to take turns with a friend to complete puzzles, or alternatively use Versus Mode to challenge up to three opponents on the same Wii console or online using the Nintendo Wi-Fi Connection.

As a downloadable game itself, Lonpos promises more downloadable content, including new puzzles and backgrounds, in the near future.

To get your brain ticking, head over to the Wii Shop and get the game for 800 Wii Points.
