Twinned X-Sum Chaos
(Eingestellt am 20. August 2026, 15:53 Uhr von Oddlyeven)
Rules: In each of the two grids, place the digits 1 to 6 once each into every row column and region. The regions are orthogonally connected groups of six cells that must be determined by the solver.
Twinned X-Sums: A clue outside a grid gives the sum of the first X digits seen by the clue, where X is the digit in the other grid that is in the same relative position as the cell next to the clue. For example, if the top grid had a 6 clue to the left of row 4, and R4C1 was a 2 in the bottom grid, then in the top grid, R4C1 and R4C2 would sum to 6. All cells in a sum are in the same region. The cell immediately after a sum is in a different region. Clues between the two grids apply to both grids.

Took me a hot minute to understand the constraints but once it clicked it was incredibly satisfying and every digit felt hard earned but not impossible

This was my favorite puzzle in quite some time. The balance between the two puzzles-having to solve in parallel-was a lot of fun

Lots of fun. A bit small on smartphone but it was so clever that it was worth the tiny adventure.
