Logic Masters Deutschland e.V.

• Normal sudoku rules apply.
• Digits along lines must be between the digits in the circles at its endpoints.
• Law of genetics: each circle represents a bean. Green, yellow, orange and red beans are pure, that is, the numbers on them can be divided by only one prime factor (remember that 1 is not a prime), and each prime number has an unique color associated. Lime bean, on the other hand, is mixed! (it can be divided by two or more different prime factors).

Bonus: can you deduce how the laws of inheritance work to produce new beans?
