How to play
- The variables represents unique integers ranging from 1 to the number of variables;
- Multiplication is implicit:
A * B;
- Based on the clues (equations and inequations), use the grid to create relations between variables and values:
- Click once on a square to mark that value as false;
- Click twice to assign the chosen value to the variable;
- Click three times to clear the square.
- The color of a clue changes after you assign values to all of 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 all values are correctly assigned to the variables.
- Figuring out which variables can't have the lowest or the highest values is a good starting point, e.g,
A > B shows that
A ≠ 1;
- Analyzing the hypothetical equation
C + D = 4, we can make the following statements:
- Another quick tip:
A = 2B means that
A is even;
- Don't be afraid of using pen and paper. Some puzzles might require it.
