Tango Unlimited: Binary Puzzle

New Unlimited Sun & Moon boards plus a fresh daily puzzle. Every grid is guaranteed solvable by logic alone—no guessing. Build your streak and beat your best time!

Two symbols, one simple rule, and a puzzle you can play forever.

Tango Unlimited is a Sun & Moon logic game with unlimited boards and a fresh challenge every day. There's no daily limit and no guessing—every grid is generated to have exactly one solution you can reach through pure logic.

Stuck on a square? A teaching hint reveals the next certain cell AND the rule that proves it, so you sharpen your skills instead of just handing you the answer.

【How to Play】 Fill the 6x6 grid with suns and moons so that every row and column has an equal number of each, no three of the same symbol ever sit in a row, and the = and x signs between cells show which neighbors must match or differ.
