This week’s mobile Humble Bundle is full of board games, the digital kind. I can personally say that I dig the Galaxy Trucker app. Link
For $1 you get Carcassonne and Scotland Yard.
For $3 you also get Splendor, Catan, and THE aMAZEing Labyrinth.
For $5 of more you also also get Ticket To Ride, San Juan, and Galaxy Trucker.
More games will be added.
