Dropping Drops

In Dropping Drops, players are simultaneously revealing cards and adding them, in numerical order, to the bottom of a grid of cards. If a card ends up being placed orthogonally next to a card of the same color, the player who played that card takes that group of cards as a penalty. Then, the columns of the grid collapse, and additional orthogonal matches may be created; the player would take those as penalties too. The player with the fewest penalty points wins!
