Speed Run is a compendium trick taking game where each player is the declarer every hand! In a compendium game there are multiple objectives (known as contracts) that each player must complete by the end of the game.
Normally in compendium games, there is one player (known as the declarer) who picks a contract for the hand and only their score counts. So, with 3 players in a 5 contract game, it would take 15 hands to play a full game.
However, in each hand of Speed Run, all players are the declarer making it possible to complete 5 contracts in 1/3 the time.
Additionally, there are Pass and Redo contracts which can provide players a chance to avoid doing a contract with a bad hand or redo a previous contract that they did not score well in. Finally, there are rules for a medium length and long length game.
