Tango, free online — daily and unlimited
Equilux is a free online version of the Tango puzzle, the sun-and-moon logic game made popular by LinkedIn. Fill the 6×6 grid with suns and moons until every row and column holds exactly three of each. Unlike the official game, Equilux gives you a fresh daily board, unlimited Tango puzzles, and a playable archive — all free in your browser. The name comes from the equilux, the day when daylight and darkness are equal.
- Balance every line Each row and column gets exactly 3 suns and 3 moons.
- Never three in a row No three identical symbols may touch, across or down.
- Respect the signs Cells joined by = match; cells joined by × differ.
- Pure logic One unique solution, always solvable without guessing.
If you already play Tango on LinkedIn, or classic Binairo and Takuzu, you know the rules. Equilux adds what Tango players keep asking for: unlimited free puzzles in three difficulties, every past daily kept playable forever, and a hint system that teaches the logic instead of just filling in a square.
Frequently asked questions
Is Equilux really free?
Yes — the daily puzzle, unlimited mode, the archive, and hints are all free to play in your browser. No account needed. Your progress and streak are saved on your device.
Is this the same game as LinkedIn's Tango?
Same rules, same 6×6 sun-and-moon board, same = and × signs — so Tango fans will feel at home immediately. Equilux is an independent, unofficial game and is not affiliated with or endorsed by LinkedIn.
What happens if I miss a day?
Your streak resets, but the puzzle doesn't disappear — every past daily stays playable forever in the archive.
Are the puzzles the same for everyone?
Yes. Each date has one fixed puzzle worldwide, so you can compare times with friends — and it's the exact same puzzle in the Equilux iOS app.
