Autumn

About Autumn, from BoardGameGeek:

Autumn, a game of paths and falling leaves, is a 18 cards minigame. In Autumn each player takes turns placing a card on other previously played cards. Each card shows four groups of leaves and, in order to play it, you should place it overlapping other cards in play, covering one or two groups. The goal is being the player with the largest area of connected leaves at the end of the game.
