Tango

How to play tango

If you’ve played Tango on LinkedIn, you know the rules already. Fill every cell with a sun or a moon:

• Every row and every column holds as many suns as moons.
• No more than two of the same sit next to each other, across or down.
• Two cells joined by = hold the same symbol. Two cells joined by × hold different ones.

Some cells start filled in. Everything else follows from the rules, so you never need to guess.

Tips for faster tango solves

Look for pairs and gaps

Two suns side by side means the cells on both ends are moons, or there would be three in a row. A gap between two suns works the same way: the cell in the middle has to be a moon. These two moves solve most of an easy grid.

Count each line

A 6×6 row holds three suns and three moons. Once a row has all three of one symbol, every empty cell left in it takes the other. Check the lines that are nearly full first.

Follow the signs

A sign next to a filled cell fills its neighbour straight away: = copies it and × flips it. Even between two empty cells, a × tells you that pair holds one of each, which helps when you count the line.

Think a line ahead

On bigger grids, try the ways a row could still be finished. If every way puts a moon in the same cell, that cell is a moon. When even that runs out, try a symbol in one cell and see whether it leads to three in a row. If it does, the other symbol goes there.

A new tango puzzle every day

Owlpuzzles has a new tango puzzle every day at midnight in your time zone, and it gets harder through the week. Monday and Tuesday are 6×6 grids that pairs and counting can solve. Wednesday and Thursday are 8×8 grids where you’ll think a whole line ahead. Friday to Sunday are 10×10 grids that need a “what if” or two.

When one a day isn’t enough, there are 300+ tango levels from easy to hard, and the archive keeps the last 30 days. A solver checks every puzzle before it goes out, and only puzzles with exactly one solution are published.

Tango on LinkedIn, binairo and takuzu

LinkedIn added Tango to its daily games in 2024, next to Queens and Zip, with one tango a day. Here you get a new one every day too, plus 300+ levels and unlimited play.

The puzzle itself is older and has many names: binairo, takuzu, binary puzzle, or 0h h1. The classic version uses 0s and 1s instead of suns and moons, and often adds a rule that no two rows or columns are the same. LinkedIn’s version swaps that rule for the = and × signs.

Questions about tango

Is this the LinkedIn Tango game?

No. Owlpuzzles isn’t part of LinkedIn. The puzzle has the same rules: suns and moons, half and half, never three alike, and the = and × signs.

Can I play tango unlimited?

Yes. Unlimited tango makes a new puzzle whenever you like, at easy, medium or hard, on top of the daily and 300+ levels.

How do I play more LinkedIn tango?

LinkedIn has one tango a day. Owlpuzzles has the same rules with a new tango every day, 300+ levels and unlimited play, all free.

Is tango the same as binairo or takuzu?

Very nearly. Binairo and takuzu use the same half-and-half and never-three rules. Tango adds = and × signs between cells and drops the rule about identical rows.

Does every tango puzzle have one solution?

Yes. A solver checks every puzzle before it’s published, and only puzzles with exactly one solution go out.

Is tango free?

Yes. It plays in your browser on a phone or a computer, with no download and no sign-up. A free account only keeps your streak and stats on every device.
