I taught Kyle how to play sudoku and then made a bunch of grids copied out of my book so we could race. When we woke up the next morning, Jason completed all the grids while everyone else slept in. I made more blank ones so we can all race with the same puzzle. 

Sudoku skill ranks as follows: 1) Me or Jason. 2) Jason or Me. 3) Curt. 4) Kyle. 

Once we race a couple times we will know for sure who is the best sudokuer.
