The ultimate brain rack for the summer holidays

So you thought our Hexadoku puzzles were hard to solve? ”You ain’t seen nothing yet”! For this year’s Summer Circuits issue we’ve designed Alphadoku, a super version of Hexadoku you’ll find so complex we’re pretty sure it will take you every spare hour or even the better part of your summer holidays to solve.
Lots of Elektor Electronics readers have taken a great liking of the Hexadoku puzzle printed for the first time in our January 2006 issue. Feedback from you all indicated that the electronics-oriented Hexadoku was a welcome change from the well established Sudoku puzzle. Despite the varying degree of difficulty of the puzzles we get hundreds of correct solutions every month, a clear sign that lots of Elektor Electronics readers (and their family members) like to exert their brain to the maximum.
