Nintendo Life writes: "This past summer, sudoku-holics were blessed with Hudson's Sudoku Student and Sudoku Master, which brought hand-crafted puzzles straight from Nikoli to the DSi Shop. However, where Student was for beginners and Master had a little bit of something for everyone, Sensei brings the pain with 100 of Nikoli's hardest puzzles to tantalize your already number-numbed brains."
The Nintendo DSi shop is also packed with delights this week, as both Electroplankton Beatnes and Electroplankton Hanenbow arrive at once. Sudoku fans will also be excited to hear that one hundred new tricky puzzles are now available to enjoy with SUDOKU SENSEI.
