Passionate about puzzles and lovers of logical challenges, prepare your neurons because I have just discovered Tangoa little puzzle game that will make your head spin (in a good way). If you like Sudoku but are looking for something more refreshing, you will be served!

The basic principle is disarmingly simple: you must fill a grid with only two symbols – suns (☀️) and moons (🌙). Here are the rules that give the game its salt:

  1. The rule of neighbors : No more than two identical symbols side by side. Forget the alignments of three suns (☀️☀️☀️) or moons (🌙🌙🌙)!
  2. The perfect balance : Each row and column must contain as many suns as moons. For example, on a line of 4 squares, you need exactly 2 suns and 2 moons.
  3. Equal signs (=): Two boxes connected by this symbol must contain the same star. If you have ☀️=[]the empty box must necessarily accommodate a sun.
  4. Opposites (×): The symbol × indicates that the boxes concerned must contain different stars. A sun on one side necessarily implies a moon on the other.

What makes Tango particularly interesting is that it leaves no room for chance. Each puzzle has a unique solution, accessible only by logical deduction. Like in Sudoku, every decision you make must be based on the rules and symbols already placed.

The beauty of the game lies in the interaction between its different rules. Let's take a concrete example:

  • You place a sun in a box
  • This box is connected by an = symbol to another
  • This second box must therefore receive a sun
  • But be careful! This could create an alignment of three suns…
  • You must therefore review your initial strategy

The developers have done a great job on the difficulty curve. The first levels allow you to assimilate the rules one by one, before confronting you with more complex grids. You will start on 4×4 grids to familiarize yourself with the mechanics, before moving on to more robust formats.

Here are some tips to improve your technique:

Start with strong constraints : Boxes connected by = or × symbols are often a good starting point.

Think balance : If a line already has three suns in four squares, you know that the last one must be a moon.

Visualize the consequences : Before placing a symbol, think about the impact on the surrounding squares.

Don't hesitate to go back : If you reach a dead end, perhaps one of your previous deductions was incorrect.

The refined interface perfectly highlights the mechanics of the game. No unnecessary frills, just you, your grid, and your neurons in turmoil. The symbols are perfectly readable, the interactions fluid, and the absence of a stopwatch allows you to think at your own pace.

Tango is a little gem that really deserves your attention. It's the kind of puzzle that makes you feel smarter after each puzzle you solve. The rules are simple to understand but offer remarkable depth of play. In short, whether you are a veteran of logic games or simply curious to tickle your brain, I highly recommend you try. And be careful, it's highly addictive!
