Purple Moose Plays...Goblin Vaults (solo)

About Goblin Vaults, from BoardGameGeek:

In the dark corners of Kulbak Prison, away from the prying eyes of the construct guards, inmates play a game of Goblin Vaults in secret... Goblin Vaults is a strategy card game for 1-5 players featuring bidding, card placement, and scoring patterns. In the game, you wager cards to win loot from the central cell block, then stash that loot wisely in your vault, earning gears based on the position of cards within that vault. You can also gain gears from scoring objectives that change each game. With cunning and clever scheming, make your bid to be feared amongst your peers! You'll need wits and luck to play your cards right as you fill your vault and influence the warden in your favor. After nine rounds, whoever has the most gears wins! -description from the publisher
