Puzzle with an electronics touch

Hexadoku january 2011

A new year brings new opportunities, hopefully also for our monthly Hexadoku competition. This month we present a puzzle that’s slightly more difficult than usual, but feel free to disagree and find it a walk in the park. Enter the right numbers in the puzzle, send the ones in the grey boxes to us and you automatically enter the prize draw for four Elektor Shop vouchers. Have fun!
