Red Dead Redemption has a bunch of different gambling mini-games to help players make money. While games like Poker and Blackjack are more recognizable, many fans were introduced to Liar's Dice for the first time in RDR1. Liar's Dice can be first played after the main story mission "Man is Born Unto Trouble," given by Irish. Afterward, games can be started in Escalera, Casa Madrugada, and Thieves Landing.
