Gameplay:
On each Turn, a player will draw one card from the deck and then either discard a card from their hand or play a card from their hand. If a player plays a card, they must discard a card of the same color.
If a player has four unique Fish in their hand, they must discard one of the Fish and then draw a new card.
If a player has Five cards in their hand, they must discard one card.
End of Game:
The game ends when one player has four unique Fish in their hand. That player is the winner!
