As if hundreds of Sudoku puzzles in Brain Training wasn't enough, Nintendo have announced Sudoku Gridmaster!

This summer will see the release of Sudoku Gridmaster on the DS, which will apparently feature over 400 of the popular number puzzles selected by the original creators of the phenomenon themselves. Unsuprisingly, you'll be playing via the device's touch-screen, as you battle to fit all the numbers in correctly.

The title is currently scheduled for a release on June 26th in America, with a European release date expected to be announced soon. This new collection of puzzles comes in addition to the selection of Sudoku grids added to the English language version of Brain Training, out shortly in the West.
