20 Strongis a new deck-based solo game system capable of being played in about 30 minutes or less.

The object of a game of20 Strongis to progress through a shuffled deck of cards, each card bearing a unique challenge. This challenge could be in the form of an enemy, a unique 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 (these dice, along with three adjustable stat dice, make up the 20 in20 Strong).

If you roll enough successes, you complete a cards challenge and gain its rewards. If you dont, you take damage and move on to the next card unless, of course, your HP stat is reduced to 0, costing you the game. If you manage to make it through an entire deck, you take on one of the decks final bosses, attempting to score enough hits against this powerful enemy to claim ultimate victory.

Of course, its never so easy that youd want to spend all of your dice on a single card. In addition to your HP Stat, youre also keeping track of your Strategy (which controls how many rerolls and items you have) and your Recovery, which controls how many dice return to your pool after taking on a challenge. If you roll more dice than your Recovery, those dice are exhausted, lowering your pool for your subsequent challenges. Its a game of pressing your luck, strategic decision-making, and resource management.
