SUN AND MOON BALANCE

Tango allows you to tap an empty cell to install a sun in it, tap again to turn it to a moon and tap a third time to clear it. Fill in the whole square grid so that each row and each column has the same amount of suns and moons. Clues are shaded cells and cannot be modified. Each board also prevents three matching symbols from appearing consecutively across a row or down a column. A line with too many of one symbol, or three identical symbols in sequence, breaks the puzzle rules immediately.

Keeping Lines Within Limits

An equals sign between two cells means both cells contain the same symbol. A cross sign means the two cells contain opposite symbols. These links can determine nearby cells when one side is already filled. Two suns side by side require moons at both ends when those cells are open, and the same applies in reverse for two moons. Once a row or column has reached its full count of one symbol, every remaining cell in that line must use the other symbol.

ACROSS DAILY BOARDS

Tango has a daily 6x6 board that becomes harder from Monday through Friday. Weekend daily boards use a larger 8x8 grid. Unlimited mode provides additional boards in 6x6, 8x8, and 10x10 sizes across three difficulty levels. Easy boards focus on signs, matching pairs, gaps, and counting to half. Medium boards require considering a full row or column, while Hard boards can require testing a symbol and following the resulting deductions.

Tap Cells to Add Symbols

Hints explain the next deduction, such as a pair blocking a cell or a line that can only be completed one way. If an existing entry is wrong, the hint identifies that first. Place the next sun or moon in Tango once each rule agrees.

WHAT MAKES A SINGLE ANSWER?

Every Tango board has one solution and is designed to be completed through reasoning. The signs, line balance, and consecutive-symbol limit work together to reduce each cell to one valid choice.
