Upon presenting my first sudoku board to my sister as her Christmas gift she explained how the game works. I started to play it myself. Every time I visited I ended up playing a few rounds and promptly became addicted. So I made myself one. The box and game board are made of solid Red Oak with dove tail joints. The pegs are a Rockler product made from maple. I stained everything with General finishes gel stain and used oil based paint for the lines. I topped it off with General Finishes semi-gloss arm-r-seal. I think staining the pegs was by far the most tedious part of the whole deal. Thanks for looking.
