When players start the game the entire board, except for the center prison cells, will be hidden. As players move from their start locations, they will spend actions to flip over location tiles in order to discover the layout of each ring.
The players' main objective is to find the gate to the next ring, but as they explore they will discover tiles both beneficial and perilous. The tiles may allow them to influence the movement of enemies or the maze itself, but they may also spawn additional enemies that will hunt for the players until subdued.
THE THESEUS DEVICE GAME BOARD
All eight cards start face up. However, when using the Faulty Algorithm Difficulty Enhancer (more on Difficulty Enhancers below), the cards will start face down and players will be able to reveal them through die rolls and cards played from the players' hands which will enable players to see some of the cards to come. This allows for careful planning, as players try to anticipate how rings will line up in future rounds, as well as making sure they are not caught in the patrol of any passing guards.
When the game starts, only two cards will be activated per round, but as the players breach additional rings, the number of cards that will activate increases. When playing the recommended timed game Difficulty Enhancer, this leads to a frantic rush as players try to evade guards and find the exit while planning ahead for the next activation sequence.
