Pokémon Sleep has its similarities and also its differences with other Pokémon games. We can say Pokémon Sleep is similar to other Pokémon games, but the way, by which it is played, that is, its approach to function is quite different from others. All Pokémon games are actually all developed by Game Freak and published by The Pokémon Company and Nintendo.
Pokémon games are known to be released in pairs, with Pokémon red and blue being their first release on the 27th of February, 1996. The latest one that was published was on the 15th November 2019, which was Pokémon sword and shield. Yet, Pokémon's sleep is set, not to be released alone, but to be released together with Pokémon Masters. These pair games serve a similar purposes. They work almost the same way with Pokémon Go. The Pokémon Go gives you a point for walking, while the Pokémon sleep gives point for sleeping.
