Meet the Gloomies — little creatures from outer space who like to adorn themselves with beautiful, galactic flowers. Your aim is to grow these radiant blossoms in the first half of the game, then harvest them in the second half.

In the first half, you play cards to strategically place flowers on the board in rows, setting yourself up for good bonuses, then draw new cards. Once that's done, your discarded cards become your deck for the second half of the game. Play cards to strategically harvest flowers from rows, once again trying to set yourself up for good bonuses.

At the end of Gloomies, you receive points for your harvested flowers and any Gloomie decoration orders you've completed.
