What is Sumrex?

A logic placement puzzle where you place one rex per row, column, and colour region, none touching, so the digits beneath all six add up to today's target. One solution, no guessing required. It belongs to the math family of daily games: one shared puzzle per day for every player.

How to play

  2. Enter a calculation or answer that satisfies the rules.
