Jux - Logic Puzzle

Fill the board. Two icons, three rules, one solution. Jux is a logic puzzle played on a grid of two icons — equal halves of one circle. Every row and column holds exactly as many of one as the other, three in a row is never allowed, and the markers between cells force their neighbors to match or differ. Each puzzle has exactly one solution, and you can always reach it by pure deduction — no guessing, ever.
