How to solve Tango
Balance suns and moons, following = and ✕ signs.
Tango, the sun-and-moon balancing puzzle that took off as one of LinkedIn's daily games (puzzle fans also know it as Takuzu or Binairo), is playable here without limits. Generate as many free grids as you like, choose your difficulty, and sharpen your solving speed.
How to play Tango
- Fill the grid with suns ☀️ and moons 🌙.
- Each row and each column contains as many suns as moons.
- Never more than two identical symbols next to each other.
- An = sign between two cells: identical symbols. An ✕ sign: opposite symbols.
- Tap a cell to cycle sun → moon → empty. Grayed cells are fixed.
How to solve Tango: techniques that work
Two rules generate almost every deduction. First, no three identical symbols may touch in a line: whenever you see a pair of suns side by side, both cells flanking the pair must be moons. The same applies to a gap between two identical symbols — in "sun, empty, sun" the middle cell must be a moon, or you'd create a triple.
Second, every row and column contains exactly as many suns as moons. Count as you go: once a row holds its quota of suns, the remaining cells are all moons, no further thought needed. On a 6×6 board that's three of each per line.
The = and ✕ signs chain these deductions across the board. An = sign copies whatever you learn about one cell onto its partner; an ✕ sign inverts it. Follow sign chains before touching unmarked cells — a single placement often cascades through three or four linked cells.
Common mistakes
Players often read ✕ as "anything goes". It's a hard constraint: the two cells must be different, so learning either cell instantly decides the other.
The other classic is ignoring the count rule until the end. Counting early is what turns Tango from trial-and-error into a pure logic game — many hard boards are unlocked by noticing a row already has all its suns.
From easy to hard
Easy boards give many prefilled cells and generous signs. Hard boards start nearly empty: expect to alternate between the never-three rule, the counts, and long =/✕ chains. Tango is also known as Binairo or Takuzu — the same techniques apply to any binary puzzle.
FAQ
- Is Tango free and unlimited on LinkMyPzzl?
- Yes. Every Tango board is generated on demand in your browser — play as many as you want, for free, with no account.
- How is this different from the daily Tango puzzle?
- The daily version made popular by LinkedIn offers one grid per day. LinkMyPzzl generates unlimited boards and lets you choose the difficulty, so you can actually train.
- Does every Tango board have a unique solution?
- Yes. A solver verifies every generated board before you see it: there is always exactly one solution.
- What exactly do the = and ✕ signs mean?
- An = sign between two cells means they hold the same symbol; an ✕ sign means they hold different symbols. The signs only ever sit between orthogonally adjacent cells.
- Can a row hold four suns and two moons?
- No. Every row and every column always contains exactly as many suns as moons — three of each on a 6×6 board. This count is one of your strongest solving tools.
