The world as we know it has ended. One woman is all that remains of the human race, and she is known only by her title: The Queen. As her final decree, The Queen aims to recreate the beautiful and lush gardens of her youth. However, there is very little moisture left, so The Queen will implement a new plan.

In her travels, The Queen has accumulated a collection of out-of-commission mining robots. She has reprogrammed them all into Robotanists and will use them to turn metal and rare gems into an elaborate garden. The Robotanist AI isn't the best, but they'll try as hard as they can to please their Queen. She doesn't quite remember exactly what the gardens look like, but she'll know it when she sees it. Until then, the Robotanists will work the mines, build the garden, and place gems as they all vie to be the Queen's favorite.

The Last Garden is a worker placement and betting game for 2-4 players. Each player controls a number of Robotanists as they seek to create a beautiful garden out of scraps and gems. On every turn, a player places a Robotanist onto the board and plays a card that shifts the structures in the garden or manipulates gems. At the end of a set number of days, the player who has gained the most favor wins.
