## What is Tango?

Looking for your next daily brain workout? Tango by OlaaSoft is a captivating 6x6 logic grid puzzle based on the classic Binairo and Takuzu mechanics. Perfectly sized for your morning commute or a quick coffee break, Tango challenges you to balance the grid using pure deduction.

If you love daily logic puzzles, binary grids, or brain-teasing board games, this will become your new daily obsession.

HOW TO PLAY
The rules are simple, but the logic gets deep:
- Fill the 6x6 grid with Sun and Moon symbols.
- Each row and column must contain an equal number of Suns and Moons (3 of each).
- Never place three of the same symbol in a row or column.
- Watch the clues! An '=' between two cells means they must match, while an 'x' means they must be opposite.

GAME FEATURES
- Daily Streaks: play every day to build and protect your streak.
- Global & Weekly Leaderboards: climb the ranks against players worldwide.
- Hints & Undo: get unstuck whenever you need a nudge.
- Clean, distraction-free design with light and dark themes.

From the makers of Patches, Queens & Zip. Tango is free to play with optional ads, and a one-time purchase removes ads forever.
