In "Easy as Snake" the sequence of the words can be confusing. Because of the nature of the example, it was clear in the example but if it is more generic words one might get confused with "Uno Dos Tres" or Uno Tres Dos".

In "Hiroimono", do we have to pass all stones or only the white stones? Rules state only white stones but that won't result in a unique solution.

You need to pass all stones. Grey markings are only for the answer key.

It appears that the example puzzle for Cross The Streams got column 2 cut off a bit.

The Icebarn example has an incorrect solution. In the upper right, two arrowheads collide along the solution's path. There is a solution, it's just not that one.

Also, the third row should probably have the symbols switched.

Hebi Ichigo: Can snake touch itself? i.e. can 1 and 5 of of same snake touch, or 2 and 5 of same snake be adjacent? If so, then I could not infer this from the instructions.

Thanks to all the organizers for conducting a smooth and successful IPC. Congratulations to Prasanna for winning comfortably and Swaroop for the podium!
Shoutout to Nityant (again!) for a terrific performance to win PR and Harsh and Mihir to complete the PR winners. Hope to see you at WPCs soon.

Puzzle quality was high and all 3 rounds were enjoyable. Some of my favourite puzzles:
Summon (mind-blowing construction and by far my favourite puzzle of the championship)
Maxi Loop
Icebarn

Rest of my feedback is pretty much the same as shared in ISC.

Once again a huge thank you to all the authors and test-solvers for the time and effort put into this event.
