If you've never played a Tango puzzle before, welcome. This guide will walk you through solving your very first board step by step — no prior experience needed. By the end, you'll understand every rule and have the confidence to tackle any 4×4 or 6×6 puzzle on your own.
Basics What you're looking at
When you open 8tango and start a new game, you'll see a square grid. Some cells are already filled with symbols — either a Sun (the gold circle) or a Moon (the blue crescent). The rest are blank. Your job is to fill every blank cell with the correct symbol.
Between some cells, you'll notice small markers:
- "=" means the two cells on either side must hold the same symbol.
- "×" means the two cells on either side must hold different symbols.
These markers are your biggest allies. They directly tell you relationships between cells, and they're the fastest way to make progress.
Rules The four rules
Every Tango puzzle follows exactly four rules. If you remember these, you can solve any board:
- Balance: Each row must have the same number of Suns and Moons. Each column must too. On a 4×4 board, that's 2 of each per line. On a 6×6, it's 3 of each.
- No triples: You can never place three identical symbols next to each other in a row or column. Two in a row is fine. Three is always wrong.
- "=" means same: The two cells sharing an "=" marker must both be Suns or both be Moons.
- "×" means different: The two cells sharing a "×" marker must be one Sun and one Moon.
That's it. No hidden rules, no exceptions. Everything flows from these four.
Walkthrough Solving a 4×4 step by step
Let's work through a simple example. Imagine a 4×4 grid where the top-left cell is a Sun, and there's a "×" marker between the top two cells in the first row.
1 Use the clue
The "×" between cells (1,1) and (1,2) tells us they must be different. Cell (1,1) is already a Sun, so cell (1,2) must be a Moon. Tap to place it.
2 Count the row
Row 1 now has 1 Sun and 1 Moon, with 2 blanks remaining. Since a 4×4 row needs exactly 2 Suns and 2 Moons, we need 1 more Sun and 1 more Moon somewhere in positions 3 and 4. We can't decide which goes where yet — move on.
3 Work the columns
Check column 1. It has the Sun in row 1. Scan down — are there other filled cells? If column 1 already has 2 Suns in later rows, every remaining blank in that column must be a Moon. This is the "almost full" rule and it's incredibly powerful.
4 Watch for pairs
As you fill more cells, keep an eye out for two identical symbols sitting next to each other. If you see Sun-Sun, the cell before and after that pair must both be Moons (otherwise you'd create a triple). This "pair forcing" trick often fills two cells at once.
5 Repeat
Each cell you place gives new information to every row and column it touches. Go back to step 1 and look for clues you can now resolve. On a 4×4, this cycle usually completes the entire board in under a minute.
Common beginner mistakes
- Forgetting columns. New players often focus entirely on rows. Every cell belongs to both a row and a column — always check both.
- Ignoring the count. If a row already has its maximum of one symbol, every remaining blank is forced. Count early, count often.
- Placing without checking. Before tapping, mentally verify that your placement doesn't create a triple and doesn't exceed the symbol count. The game highlights violations in red, but it's faster to catch them yourself.
- Trying to guess. Tango puzzles are designed to be solvable by logic alone. If you feel like you need to guess, step back and look for a clue or pattern you missed. The hint button is there for exactly this moment.
What the hint button teaches you
8tango's hint system is more than a shortcut — it's a teacher. When you tap the lightbulb icon, the game finds the next cell that can be logically determined and highlights it. More importantly, it tells you which rule forces that cell.
Pay attention to the hint descriptions. Over time, you'll start recognising patterns like "almost full" or "triple prevention" before you need the hint. That's how you level up from beginner to intermediate.
When to move up to 6×6
Once you can solve most 4×4 boards without hints in under 90 seconds, you're ready for 6×6. The jump adds more cells and more complex clue interactions, but the same four rules apply. The main difference is that chains of deduction become longer — you might need to follow a clue through 4 or 5 cells before something resolves.
Don't be discouraged if 6×6 feels hard at first. It's a genuine step up. Use hints freely for the first few boards, study the patterns, and within a dozen puzzles you'll feel comfortable.
Journey mode: the guided path
If you prefer a structured learning experience, try Journey mode. It starts with the simplest possible 4×4 puzzles and gradually introduces harder boards as you progress. There are over 200 levels, each designed to teach or reinforce a specific solving technique. It's the best way to build skills without feeling overwhelmed.
Ready?
You now know everything you need to solve your first Tango puzzle. Open a 4×4 board, start with the clues, count your rows and columns, and watch the board fill itself through logic. It's satisfying in a way that few puzzles match.
