A reg or regular refers to a player who frequents or regularly participates in games at a specific poker room, casino, or online platform. A reg is typically experienced, familiar with the games, and often seen playing on a consistent basis. These players are known for their regular presence and are often well-versed in the strategies and dynamics of the games they participate in. Regs are often contrasted with recreational players, who play more casually and sporadically, with less focus on strategy and a more relaxed approach to the game.
