Logic Masters Deutschland e.V.

ChinStrap and I have teamed up yet again, this time to celebrate our friend Scojo, a certain someone suggested that he may appreciate an assortment of Copycat puzzles for his birthday and this is our contribution. Happy Birthday Scojo!

If you have any questions feel free to DM us on Discord.

Happy solving!

Rules:

• Normal sudoku rules apply. Place the digits 1-9 once in every row, column, and box.
• Slow Thermos: Values on a slow thermo must not decrease starting from the bulb.
• X-sums: Outside cells on a slow thermo have a value equal to the sum of the first X cells seen in the clue's row/column, where X is value of the first cell seen. For purposes of solution check, outside cells are not used.
• Copycat Cells: Place 9 Copycat Cells into the grid so that there is exactly one Copycat Cell in each row, column, and 3x3 box. Each Copycat Cell must contain a different digit. The value of a Copycat Cell is the digit in the cell rotationally opposite itself in the grid (180° rotation about the center of the grid). For example, if r2c3 is a Copycat Cell containing the digit 5, and r8c7 contains the digit 9, the value of r2c3 is the digit in r8c7, which is 9.
