### How to play

• The variables are numbers from 1 to the total number of variables, and each one is different;
• When you see the letters together, like "AB," it means you multiply the variables, like `A times B` or `A * B`;
• By looking at the clues (equations and inequalities), you create connections between the variables and their values using the grid:
• Click once on a square to show that the value is false;
• Click twice to assign the chosen value to the variable;
• Click three times to clear the square.
• The color of a clue changes when you assign values to all its variables:
• GREEN means that the statement is true;
• RED means that the statement is false.
• Click on a clue to mark it as used;
• The game ends when you correctly assign values to all the variables.

### Tips

• A good starting point is to determine which variables can't have the lowest or highest values. For example, if you see `A > B`, it means `A ≠ 1`;
• When you have the equation "D + E = 4," for example, you can make the following statements:
• `D = 1` and `E = 3` OR `D = 3` and `E = 1`;
• We can't have `D = 2` and `E = 2` because the variables must be different;
• Also, no other variable can be 1 or 3.
• Another quick tip: If you see `A = 2B`, it means `A` is an even number;
• Feel free to use pen and paper if needed. Some puzzles might require it.
