20 Strong is a deck-based game system. 20 Strong is a small nucleus of simple, adaptable rules that can then be applied to a variety of unique decks, each with their own set of mechanics.
The object is to progress through a deck of cards, each card bearing a challenge. This challenge could be in the form of an enemy, a scenario, or some other requirement. Challenges usually require a certain number of successes to complete, which you earn by rolling a set of 17 dice with different odds for a hit.
If you roll enough successes, you complete a card’s challenge and gain its rewards. If you don’t, you take damage and move on to the next card – unless, of course, your HP is reduced to 0, costing you the game. If you manage to make it through an entire deck, you take on one of the deck’s final bosses, attempting to score enough hits against this powerful enemy to claim ultimate victory.
