WereABC

Werewolf's world is big, full of fabulous creatures and characters! Once up a time, they got together and organized a game night called "BINGO!"
The game is simple:

Play as many cards as you want, as long as they can form up a formation;
And the next player should play cards following the last player's formation;
The last player who plays the formation wins the current round, and take all B, I, N, G, O cards among the played cards this round.
If there is a player played out his hand cards, the game night is over, and everyone calculate their five score cards: B,I,N,G,O.

5. The player who has the most B,I,N,G,O cards wins the game!
