"Everyone knows what Sudoku is. The Amstrad CPC 6128 game Sudoku Master, however, has been in development since my days on the Amstrad Action tribute magazine. It featured in our news section and in the interview with Olivier Floquet (a.k.a. eliot), the main man behind it all. Well, the game has finally been completed and is available to purchase in 3.5" disk format from Binary Sciences' website for €6.00EU plus postage fees. A download version will become available on July 25th."
