Logic Masters Deutschland e.V.

Last week, Scojo hosted a "guess the setter" challenge where puzzle makers were instructed to create a puzzle typical for their style and submit it anonymously. Scojo solved all of the 22 submissions and tried to assign every puzzle a setter. I decided to impersonate another setter for the challenge. Can you figure out who it was? Thanks to scojo for solving this on stream and to the CtC discord for testing. Hope you enjoy!

• Chaos Construction: Divide the grid into 8 regions of orthogonally connected cells. Fill the grid with the digits 1-8 so that each digit appears once in each row, column and region.
• Same Difference: Adjacent digits on the same same difference line must have the same difference. Differences may be different for different same difference lines.
• Counting Circles: A digit in a circle indicates the number of circles (of any color) containing that digit.
• Circle Count: A digit in a red circle indicates the number of yellow circles in the same region.
• Minesweeper: A digit in a yellow circle indicates the number of cells of the same region in the (up to 9) surrounding cells, including itself.

Example Puzzle

The same difference lines have constant differences (0 and 1). Both yellow circles (minesweepers) see 2 cells of the same region (themselfes and the cell above) in the surrounding 3x3. The red circle is satisfied since the region has 1 yellow circle in the region.
