Play Tango online, for free
Tango is a free logic puzzle you can play right in your browser, with no download and no sign-up. The rule fits in one sentence: equal suns ☀ and moons ☾ on every row and every column, never three identical symbols in a row, and the = or × clues force a relation between two neighboring cells. Easy to grasp, yet every grid rewards pure deduction, never luck.
In progression mode, grids grow from 6×6 to 10×10 and get harder as you go: from Easy all the way to the Master rank, the summit reserved for the best. These are unlimited Tango puzzles, and the game is free, with no counter and no daily cap. Prefer to stick to one format? Pick a size and solve unlimited grids. Every day, a challenge shared by all players awaits, with a leaderboard and a streak to keep alive. Tango works just as well on desktop as on mobile, built thumb-first.
