Two symbols · one perfect balance

How to play Tango

  1. Fill every cell with a sun or moon. Starting symbols cannot be changed.
  2. Balance every row and column. Each one must contain the same number of suns and moons.
  3. Never place three matching symbols together. This applies horizontally and vertically.

Click a cell to cycle its symbol, or use arrow keys with 1 and 2. Every puzzle has exactly one answer, so no guessing is needed.

How to play Tango

Fill every empty cell with either a sun or a moon. Each row and column must finish with exactly the same number of both symbols. You may never place three suns or three moons beside one another horizontally or vertically. Starting symbols are fixed.

Tango strategy

Break up matching pairs

Two matching symbols beside one another force the cell on either open end to be the opposite symbol. The same idea works when two matching symbols have one blank between them: the middle cell must be the opposite symbol.

Finish a line when one symbol reaches its limit

A 6×6 row can hold only three suns and three moons. As soon as three of one symbol are placed, every other blank in that row must use the other symbol. Apply the same count to columns.

Combine both rules

Filling a forced cell often creates a pair or completes one side of another line. Scan its row and column after every placement. Harder boards are solved by repeating these short deductions, not by guessing.

Difficulty levels

Easy uses compact 4×4 boards. Medium moves to 6×6 with more starting symbols, while Hard offers sparser 6×6 layouts. Expert expands to 8×8 and requires longer chains of deductions. Every grid is symmetrical and verified to have one solution under the rules shown here.

Share a fixed-seed challenge

The challenge panel below the board turns the current puzzle into a short link that always opens the exact same grid. Send it to a friend and compare solve times on identical clues, or copy it from the address bar - the page URL always points at the puzzle on screen.

Frequently asked questions

What are the rules of Tango?

Fill each cell with a sun or moon. Every row and column must contain equal numbers of both symbols, and no three matching symbols can touch in a straight line.

Does every Tango puzzle have one solution?

Yes. Every bundled starting grid is checked by an offline solver and published only when the visible clues produce exactly one valid answer.

How do mouse controls work?

Left-click an empty cell to cycle from blank to sun to moon. Right-click cycles in reverse. You can also select a cell and use the three large input buttons.

Can I play Tango with a keyboard?

Yes. Arrow keys move, 1 or S places a sun, 2 or M places a moon, Space cycles a cell, Backspace erases, H uses a hint and Control-Z undoes.

Can a friend play the same Tango board?

Yes. Every unlimited puzzle has a fixed seed and a short challenge link. Share it from the panel below the board and the recipient starts from the exact same grid, so solve times are directly comparable.

Is Tango Unlimited affiliated with LinkedIn?

No. This is an independent puzzle implementation and is not affiliated with or endorsed by LinkedIn.
