Some time ago, company Doomsday Robots lunched a kickstarter for their new game Bridges to Nowhere.
I pledged for PnP files, and the time finally came when they arrived.
The game itself uses drafting mechanism, where you draft bridge elements and then try to build them into your bridge in order to maximize points. Points can be earned from bridge segments (Each built in segment brings specified number of victory points by itself. Matching symbols on adjacent tiles and using specific tiles like monuments and toll stations can significantly boost your point total) or by fulfilling specific contract conditions predefined before each game.
Solo game is well designed, dummy player will always take the best cards and you have to use all your wits to outsmart it. Normal difficulty gives just the right challenge for average player.
