I created this puzzle with my son Linus. Playing it means racing a soapbox race. We'd like you to post your race (solving) times.
Standard sudoku rules apply: The digits 1 through 6 appear in every row, column, and box.
Thermometers: Digits on Thermos are strictly increasing from bulb to tip.
XV-Dominos: Cells separated by an X must sum to 10. Cells separated by a V must sum to 5. Not all Xs and Vs are necessarily given (no negative constraint).
Solution code: Row 2 left to right.
