Wolves, as in the animals in the real world who walk on all fours, do play some games...But usually only younger wolves do. Some ideas for games that wolves in the wild play include: Chase/tag, wrestle, hunt(some wolf pups can for example pretend to hunt a rabbit, which is really a pinecone), race, and puddle jump(basically wolves jumping in puddles). These are just some of the possibilities for games. Just use your imagination, I guess :)
