The Hatching Machine is used to reveal new Bees from Queen and Bee Eggs. You can create these eggs by redeeming Egg shards.
You can use the Hatching Machine on our Hatching Website or by vising the Bee Lab inside of Honeyland. As new Universes are introduced in the game, they will subsequently become available in the Hatching Machine.
NOTE: You can learn more about Hatching Gen Z Bees here.
