hi!
1 The game shuffles an array with the cards then picks them in order. The initial deck contains 10 of each card type
2 My game uses a different system to determine the winning hand by calculating a value based on what you got (pair, 3 of a kind ecc) and the value of the cards you own. I already was encountering situations of different hands ending up in a tie so i tried mitigating by using different values but there may still be cases of equal sums with different hands.
