The Double-Set Bonus Routes for Blocky Mountains were offered as a "goody" incentive for supporting the Startnext campaign to fund the creation of Blocky Mountains. Order a two-game bundle, get the Double-Set Bonus Routes that utilize them. This includes three Level 3 route cards, each of which requires two full sets of Blocky Mountains blocks in order to create them, and uses both sides of the card to clearly depict the rather difficult requirements of the route.
