Nikola

We'll include the sizes in the IB. For now, I can add that, each puzzle can be printed on A4 size page, and the cell sizes will still be large enough.

Marathon will last 8 full days. The organizers felt that holding this competition so close to the beginning of the year would mean that solvers would have ample vacation time to take the week off from work for solving these puzzles.

Think I have found an error in the IB. For "Loop the Loop":
"Answer key 1: For each marked row, enter the number of cells of the longest horizontally connected group of
cells inside the loop in that row. For the example, answer key is 945"
BUT the longest INSIDE the loop for the second selected row is 3... the 4 cells are outside the loop.

Or have I misunderstood and it means the longest horizontal stretch (regardless of whether inside or outside the loop)?

And for TAPA the answer keys appear to be reversed

It is longest inside the loop (same as Double Decathlon). So 935 is the correct answer key. Updated pdf uploaded.

I know there is nothing indicated regarding this in IB but just to clarify it.

While playing around with the rules of Black and White Loop, I made two puzzles which you can find on the Rätselportal: http://www.logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000... and http://www.logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000...

Does anyone have links to other puzzles of the type? I find it hard to get my head around.

Excellent puzzles rob. The 2nd one is really well made with lot of local and global solving. It is always interesting to start solving a loop puzzle from middle of the grid.

I had not seen this type, until Zoltan suggested that we include this type. He shared a smaller example as well (attached with this post)

I haven't ever seen them online. they did feature in Breinbrekers, but haven't been in there in recent years. I thought I had a few laying around, which I had made. But the only ones I can find use 2 turns between different balls. I don't expect the puzzle to be as heavily clued as yours though. At least they weren't in Breinbrekers.
