Hexadoku March 2011

This month’s Hexadoku is unusual and pays homage to our long term readers and faithful subscribers. To be able to complete the grid and find the solution you’ll need the solutions to previous Hexadokus dug out from your archives or cleverly found using the Elektor website. Enter the right numbers in the puzzle, send the ones in the grey boxes to us and you automatically enter the prize draw for one of 10 Cypress FirstTouch PSoC 5 starter kits. Have fun!
