Tango — Free Daily Binary Logic Puzzle
Balance every row and column.
Tango is a free daily logic puzzle: fill the grid with suns and moons so that every row and column ends up perfectly balanced, with no three of the same symbol ever sitting in a row. A few cells come pre-filled, and a handful of '=' and '×' hints on the edges between certain cells tell you when two neighbours must match or must differ. From there it's pure deduction — one unique arrangement satisfies every rule at once. Free, no signup, one new board every day at 00:00 UTC, with unlimited practice in between.

Rules
Fill every cell with a sun or a moon. Tap once for a sun, again for a moon, and a third time to clear it.
No more than two of the same symbol can sit next to each other in a row or column.
Every row and every column must end up with an equal number of suns and moons.
An "=" between two cells means they must match. A "×" means they must differ.
Some cells start pre-filled and can't be changed — use them as your anchor points.
A new board appears every day at 00:00 UTC. Practice mode is unlimited.
How to play Tango
- 1The grid holds suns and moons. Tap an empty cell to place a sun, tap again for a moon, and a third tap clears it.
- 2No more than two of the same symbol can sit next to each other in a row or column — three in a row is never allowed.
- 3Every row and every column must end up with an equal number of suns and moons.
- 4An '=' between two cells means they must match. A '×' means they must differ.
- 5Some cells are already filled in and can't be changed — build outward from those.
- 6The board is solved the moment every rule is satisfied at once — it's detected automatically.
- 7The daily board resets at 00:00 UTC and is the same for every player.
Tango strategy
Two of a kind forces the third
The instant two identical symbols sit next to each other, every cell touching that pair on either end must be the opposite symbol — otherwise you'd make a run of three. This single rule resolves more of the board than any other trick.
Finish a row or column early with simple counting
Once a row already has its full share of suns, every remaining blank cell in that row must be a moon, and vice versa. Scan for rows or columns that are one or two symbols away from their limit — they're usually solvable outright.
Chain through the '=' and '×' hints
An '=' or '×' hint is only useful once you know one side of it. Solve the plain cells first, then let each hint push its value onto the next cell, and the next — a single early deduction often cascades through a whole line.
Tango vs LinkedIn Tango
Same core rule set — balanced rows and columns, no three in a row, '=' and '×' hints between cells — with a few differences in how it's served.

Tango — frequently asked questions
What is Tango?
Tango is a free daily logic puzzle. You fill a grid with suns and moons so every row and column is balanced and no three of the same symbol sit in a row, using a few pre-filled cells and '=' / '×' hints between neighbours.
How do you play Tango?
Tap a cell to cycle it through sun, moon, and empty. Keep every row and column balanced with no three of the same symbol in a row, respect the '=' and '×' hints between neighbouring cells, and the board detects the solve automatically.
Is Tango the same as LinkedIn Tango?
The core rules match — balanced lines, no three in a row, '=' and '×' hints. This version needs no account, adds unlimited free practice, and includes a timer and leaderboard.
Is Tango free?
Yes, the daily board and unlimited practice mode are both free with no account required.
What's the difference between Normal and Hard mode?
Normal is a 6×6 board with three suns and three moons per line. Hard mode (Pro) is an 8×8 board with four of each — more cells and a tighter count to balance.
Is there always exactly one solution?
Yes. Every board is generated by starting from a full valid grid and removing clues one at a time, checking after each removal that exactly one completion still exists.
