Drake's Gambit

A popular game for both casual and high stakes competitive play all around Dynos. Two or more players use a deck of cards (ranging in value from 1 through 10) and accompanying polyhedral dice sets to play. The goal is to get as close to 20 without going over. The game is so named as the ideal way to win is to minimize how much you need to wager while hoping to maximize how much your opponents wager.
Players or the host first decide the value of the game (Copper, Silver, or Gold). Players alternate taking turns. On a turn, a player draws 1 card (roll a D10). Once per turn, the player may then add to the wager to roll a specific die as shown below, either adding the rolled value to their total or doubling the Dice Wager to subtract the value from their total instead (to a minimum of 0). If a player gets to a combination of 10 cards and dice rolls without hitting 20, they automatically Win on that Hand regardless of the other players' totals. Being over a total of 20 at the end of a turn is referred to as a Bust, and loses the Hand. A Player can stop on any turn before hitting 20, referred to as a Stand. A Match consists of a number of Hands, with a limit of 4 Dice Wagers per Player per Match. The first player to win 3 Hands wins the Match and takes the full pot of buy-ins and wagers. Dice Wagers (X = game value piece, round up for Copper):

• 1X = +D12, 2X = -D12
• 1.5X = +D10, 3X = -D10
• 2X = +D8, 4X = -D8
• 2.5X = +D6, 5X = -D6
• 3X = +D4, 6X = -D4
• 3.5X = +D3, 7X = -D3

Leagues: Competitive leagues will have a buy-in wager in order to play, with a small cut taken for upkeep fees. Leagues typically split their player base by percentage rankings - Copper: new players / bottom 50%, Silver: 51-80%, Gold: top 20%. A player can challenge any other player in their respective tier. A player can advance tiers only by climbing to the top rank in their current tier (determined by number of wins, or win-loss ratio in larger Leagues), then beating the lowest ranking player of the next tier.
Variant: Blind Dice In this version of the game, often played at Tournaments and among top League players, the players must declare their 4 Dice Wagers for the Match before any cards are drawn. The monetary value of the Die is only added to the pot once it is rolled, but in this way the players must be more strategic in their choices. In Blind Dice games, a third Wager option is added to triple the Die's monetary value, granting the player the choice of whether it is positive or negative AFTER rolling.
Tournament Scoring: In a Blind Drake's Gambit Tournament, players compete by point totals across a set number of Matches. Each Hand won is worth 1 point, and each Match won is worth an extra 2, for a total of 5 possible per Match. No points are awarded for Hands which Tie. Participants pay an entree fee, and their Dice Wager choices are made between matches, with half of the wagered coin added into the Tournament Prize pot (the other half is kept as winnings for individual matches). There are also a number of potential bonuses, which will be specified by the Tournament overseers. The most common bonuses include: Clean Slate (+1): Win a Match without your opponent winning a single Hand Luck of the Draw (+2): Win a Match without your opponent scoring and without using any Dice. All or Nothing (+1): Complete a Match using either All or None of your 4 Dice Wagers. Good Sport (Tiebreaker): The player with the most positive ratings by their opponents gets a separate accolade, and wins out if they tie in score with any of the Top 3.
