In this game, you use logic to figure out the values of different variables by solving equations. You do this by using the grid below. The game is updated 4 times a day: 09:00, 13:00, 17:00, and 21:00.

- 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.

- 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.
