Hexadoku April 2011

After last month’s heavily Elektorized Hexadoku we revert to the standard grid of 16 by 16 boxes you’ve grown accustomed to these past few years. Sharpen your pencil, sit down in a WiFi-free spot and enter the right numbers in the puzzle. Next, send the ones in the grey boxes to us and you automatically enter the prize draw for one of four Elektor Shop vouchers. Have fun!
