Özelleştirmek İçin;
int secretCode[maximumKnocks] = {25,100,25,25};
olan yeri eleman sayısı +1 vuruş olarak düşünün.Yani ben ilk vurduğumda 25'ten öncesi oluyor.Daha sonraki bekleme 100'ü sonraki üste üste 2 kere vurmalar 25',i temsil ediyor.Bu sistemi çözmeniz uzun sürmez.Bir kaç örnek ve kendi düşünme tarzınızla istediğiniz her kodu yaratabilirsiniz.

25 = Üst üste beklemeden tıklatma aralığı
50 = yarım saniye civarı bekleme aralığı
100 = 1 saniye civarında bekleme aralığını temsil etmektedir.
Bunlar olacak diye bir şey yok.42,74,92 gibi sayılar da yapabilirsiniz.
