Solving puzzles while watching over a small baby is not the best way to stay focused during a sprint. Never trust that a baby will sleep 80 minutes straight at nap time.
I guess I didn't do too badly considering this, but without baby I probably would have finished... oh well, one never knows.

Thanks for the contest; the title suggested a sprint and I really enjoyed the pace. A few hiccups for me - surprisingly on the Battleships which was my favorite puzzle but where after the key insight I didn't explore possible 3-ship space really well, and also on the Number Snake where my mind was telling me "digits don't repeat in columns/rows" around a clue so I couldn't make the 15 work. I must be solving too many puzzles these days as practice. I'm confusing all the rules!

123 GO is now over. Password removed from booklet.

Thanks to everyone for participating and I hope you enjoyed the puzzles. Congrats to Palmer, Florian and Ulrich for the top 3 places.
I'm glad that many players were able to finish the test. I believe Instant Grading was helpful to many players, and any feedback regarding it, or the puzzles or the test, is welcome.

Thanks to Nikola Zivanovic for testing the puzzles.
Good Luck to everyone for the World Championships next week!

I was unhappy after I was done as I wasted at least 5 minutes on the fillomino as I hadn't noticed I had made a typo and thus thought I had made a solving error. Overall my result isn't that bad. Had fun overall.
