About the gameHow Tango works,
How Tango works,
in short.
- Step 01
Suns and moons.
Each puzzle ships with a few suns and moons placed. Edge marks "=" or "×" say which neighbours must match or differ.
- Step 02
Tap a cell to cycle Empty → Sun → Moon.
Each tap rotates through the three states. The board flags conflicts as you go: no three of the same symbol in a row, and no more than three of either per row or column.
- Step 03
Three each per line.
Every row and column ends with exactly three suns and three moons, every edge mark satisfied — the board is solved.
Questions
Tango questions, answered.
Tango is a deduction puzzle inspired by the LinkedIn daily game of the same name. You fill a 6x6 grid with suns and moons so each row and column contains exactly three of each, no three identical symbols sit next to each other, and every edge constraint between adjacent cells is satisfied.
Tap an empty cell to place a sun. Tap again to switch it to a moon. A third tap clears it. Some cells start filled and are locked as clues — those tell you where to begin. Solve each puzzle through logic alone; no guessing is ever required.
A green = between two adjacent cells means they hold the same symbol — both suns or both moons. A clay × between two cells means they must hold opposite symbols. Treat them as locked relationships and use them to chain deductions across the grid.
It is one of the three constraints. Across any row or column, no run of three consecutive cells may share a symbol. If you place a sun next to two existing suns, the cell highlights in clay to show the violation — undo by cycling through to a moon or back to empty.
Yes. The generator verifies uniqueness at creation time by counting solutions and rejects any puzzle with more than one. You should always be able to reach the answer with deduction — if you get stuck, ask for a hint.
Hint reveals one correct cell, locking it in as a clue. It does not penalise your time, but it bumps the hint counter shown at the end. Use sparingly — the satisfaction of finishing without one is the point.
Tango uses the same row, column, and no-three-in-a-row rules as Binairo and its cousins, but adds explicit equality and difference constraints between adjacent cells. Those edge constraints both make easier puzzles tractable without lots of clues and create branching deductions that pure Binairo lacks.
Yes. The board is sized for thumb taps, and a single tap cycles each cell through its three states. Hints and the new-game pill stay reachable in the top toolbar across all screen sizes.
