Quick editing note (though mostly too late, and hopefully relatively harmless):
On the submission page for the Strong Hitori, both entry blanks say "top left to bottom right", but the second one should be "top right to bottom left"

Thanks for pointing it out and an obvious overlook on my part.

Very nice puzzles Rohan.
After completing Arithmetic Box I read the puzzle twice, because there was no 3 used (I thought all numbers need to be used).
What happened with Tapa is my worst ever in LMI tests, because after solving it in 2 minutes the correct solution is right infront of my eyes, but something kept on saying in my head that the shaded cells must complete a loop :( and I kept on solving it for 6 times.
We can call this test as this years Sprint test.

There are three puzzle competitions this month but still not a single sudoku competition except Beginner's Sudoku Contest ??? When will next sudoku competition starts ???

The World Championships are starting soon, so the next test will be after that only.

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.
