Tiny Trees is a micro-expansion for Tiny Towns. In tiny trees, each mayor has a chance to watch a tree grow in their town. However, each tree only grows if it is in the only empty square on a player’s board. Place a seed on one space on your board at the start of the game. At any point if you build on this space, gain a free resource of your choice. However, if you finish the game with only the seed remaining and no other empty spaces, it grows into a 2 point tree! -description from publisher
