Find the four-fruit code
Discover the hidden sequence of four fruit symbols within ten guesses. Choose from six fruit types, and use the same fruit more than once if you want. Fill all four slots, then use Check guess; the order matters as much as which fruit you choose.
Read the two pin counts
A solid pin counts a correct fruit in the correct slot. A hollow pin counts a correct fruit in a different slot. Pins describe totals for the whole guess, not particular slots. Each hidden fruit occurrence can count only once.
Count repeated fruit carefully
If the code has one mango and your guess has two, at most one of those mangoes earns a pin. Exact-slot matches count first; the remaining fruits then supply wrong-slot matches. Find all four positions to win. After the last unsuccessful guess, the code is revealed.
