The Secrets of the Tome Bonus 

This can be unlocked when you have completed the stack of four squares on the Perimeter pattern. Once you unlock the Secrets of the Tome, you will be given five picks to make by clicking on the different sealed envelopes.

Mystery Tome Bonus

Treasure of Cthulhu

To activate the Treasure of Cthulhu bonus, you must achieve a Bingo during the first thirty balls while all four cards are active.
