About Tango Game Online

Tango Game Online is a free home for the sun and moon logic puzzle. It is a small, independent project, built by one person who plays the game every day and wanted a better place to do it.

Why this site exists

Daily puzzle apps give you one Tango grid and then make you wait until tomorrow. Most other copies online were slow, crowded with pop-ups or hard to tap on a phone. We wanted a fast page that opens straight to the board, plays well on any screen and lets you keep solving for as long as you like.

How every puzzle is made

  • A generator builds a full, valid 6×6 grid of suns and moons from a random seed.
  • Cells and clues are removed one by one, and a solver checks after every step that the puzzle still has exactly one solution.
  • Difficulty depends on how many cells and = or × clues stay on the board, so Hard needs longer chains of reasoning than Easy.
  • No puzzle ever needs a guess. If you get stuck, the hint button shows the next cell that can be worked out by logic.
