About Sumrex
Sumrex is the LinkedIn Queens family with a sum on top. Place one rex per row, column, and colour region, none of them touching — so the digits beneath the six rexes add up to today's target. One puzzle, one solution, no guessing.
Read the Sumrex rules for what counts as touching and how Check works, or browse past Sumrexes in the archive. If you're stuck, hints for this Sumrex walk through three spoiler-safe nudges. If you've played Queens, see how Sumrex compares to Queens. If you'd rather spend two minutes on numbers, Targle uses the same target-given idea on a six-character equation.
