The Instruction Booklet is published. Version 2 with the points distribution will be available tomorrow.

Note: I had messed up some of the size descriptions (Sashigane and Ice Walk sections). If you download the IB now, they are accurate.

The Tatamibari example has multiple solutions and will be fixed.

For Tatamibari, when it says rectangle, can we assume that it's not a square?

A square is a rectangle. The three different clues describe a square and two kinds of rectangles that are not squares.

New IB uploaded.
Changes -
Points Distribution added.
Line added to Ice Walk rules.
Tatamibari example fixed.

I'm actually ready before estimation so I'll be bringing the start of this one back to normal time. I'll keep the end time the same as before. So the contest starts in about 52 minutes.

Newer IB uploaded. Changes from before -
- I'd actually not changed the images with the new example, just the link, so fixed that.
- I changed the images of the Sashigane example to reflect the Competition Puzzle formatting.

Also, password protected Puzzle Booklet is now available to download.

Sorry about all the changes in the IB, but I've also made the relevant notes on the competition page.
