This Print and Play expansion for “Vault: a Solitaire Dice Game,” adds three modules to the game that will change the way that you play the original game, and add some extra replayability to the game.
Lockboxes
These cards give you one extra way of gaining gems. Rather than focusing just on the grid, you now must focus on a list of objectives you can optionally complete alongside the main Vault.
Accomplices
Unlike the original game where each play of Vault was separated, this module connects three plays to each other. In addition, it adds units that you can recruit throughout your game, all of which will give you game breaking options you never had before.
Pair of Thieves
This variant allows you to now play a co-operative version of Vault with one other thief. Complete two Vault's together to see if two thieves really are better than one.
