Sun & Moon Tango Puzzle Game

Fill the grid with suns and moons and solve a classic tango puzzle, one calm logic step at a time. Sun & Moon Tango is a binary puzzle (also known as Takuzu or Binairo) with three simple rules and plenty of room for clever deduction. HOW TO PLAY • Tap a cell to place a sun, tap again for a moon, and once more to clear it. • No more than two identical symbols may sit next to each other in a row or column. • Every row and column holds the same number of suns and moons. • Cells joined by = must match. Cells joined by × must be opposites. WHAT'S INSIDE • 600 levels on 6×6, 8×8 and 10×10 boards, from gentle warm-ups to tricky whole-line reasoning. • A new daily puzzle every day. • Earn up to 3 stars on every level. • Hints that teach: a hint points to the next cell you can work out and tells you why, or flags a cell that is wrong. • Choose how errors are shown: instantly, only when a row or column is full, or not at all. • Undo, long-press to clear a cell, and automatic saving. • Boards scale to your screen, so no rows get cut off. FAIR BY DESIGN • Every puzzle has exactly one solution, and your grid is checked against the rules. If it follows all three rules, it is solved. No "wrong answer" on a correct board. • No ads during puzzles. Ads only appear between puzzles, and an optional rewarded video refills your hints when you run out. • All 600 levels open up as you play. No paywall. Cute clay-style sun and moon friends, soft day-to-night colors and calm music make every tango puzzle a relaxing brain break. If you enjoy sudoku, nonograms or other logic puzzles, this binary puzzle is a perfect daily habit: a quick 6×6 on the bus, a deep 10×10 before bed. Start your first tango puzzle today and find the balance between sun and moon.
