Sumrex

A Queens-style placement puzzle with arithmetic on top. Six markers go on a grid of digits so that each row, column and colour region holds exactly one, none touch even diagonally, and the digits beneath them add up to the day's target. Every puzzle has one solution, and past grids are kept in an archive.
