It stands for Multi-Table Tournament. An MTT is a tournament format where players compete against each other at multiple tables simultaneously. As players are eliminated, tables are consolidated, and the tournament continues until one player accumulates all the chips or a pre-established number of players remain, depending on the tournament structure. MTTs often have set buy-ins, varying prize pools, and progressive blinds that increase at specific intervals, providing an engaging and competitive environment for players aiming to win the tournament.
