HOW TO PLAY

  1. Take long strip and find all possible combination(s) with shorter strips to get the same length as the long strip. Then make equivalence color-number.

  2. Sum. Example: 4 + 2 = 6 (Pink + Red = dark green)

  3. Subtraction. Example: 5 - 3 = 2 (yellow - light green = red)

  4. Multiplications. Example: 2×2=4 (Red = pink)

  5. Divisions. Example: 6:3=2 (dark green = 3 yellow)

  6. Build borders.

  7. Group strips of the same color and check that they have the same length.

  8. Build up and down stairs.
