The name of this set of 20 specialty dice and a rule booklet is something of a hyperbole, because there are really 12 distinct games plus 50 state games that together really equal one game, for an actual total of 13 games.
The games are as follows:
Train - Uses 6 special train car dice. Build your train with a locomotive, a caboose, and the highest value freight cars you can while avoiding "train wrecks" and "equipment shortages". Essentially a variant of Ship, Captain and Crew (below).
States Game - Uses 4 special dice numbered 2 through 6 with a USA symbol replacing the number 1. Roll the 4 dice and use the numbers showing to calculate the numbers 1 through 50 (ordinal state numbers), with the USA symbol serving as a joker.
Poker Dice - Uses 5 poker dice (faces showing Ace, King, Queen, Jack, 10, and 9). Roll the dice to get the highest poker hand.
Bar Dice - Uses 5 standard dice. Roll the dice to get the highest poker hand.
Cover the Board - Uses 2 standard dice. A little like multi-player Shutbox.
Buck Dice - Uses 3 standard dice. A little like Old Maid, but with dice.
Sequences - Uses 3 standard dice. Roll the dice and try to get the highest-scoring sequence(s) of numbers.
Accumulation - Uses 2 standard dice. Roll the dice and try not to reach the sum of 41.
Horse - Uses 5 standard dice. Roll the dice and try to get the highest N-of-a-kind.
C-Low - Uses 3 standard dice. Roll the dice and try to earn 5 points by getting the highest value hands.

Kaput - Uses 5 standard dice. Roll the dice and try to get the highest total without rolling 2s or 5s.
