Every ranked season of Teamfight Tactics starts with five placement games, also called provisional matches. Until they are played your account is only provisionally ranked for the new season, and the results of those five lobbies decide the division you start the next few months in. A TFT placement boost on Boosting24 means that a verified high-rank player plays these games for you. You choose your last known rank and how many of the five games you want covered, and the booster takes it from there.
Ranked seasons in TFT last roughly four months and are tied to the release of a new set, with new champions, traits and mechanics. At the start of each one Riot applies a soft MMR reset, pulling everyone’s hidden rating a little closer to the middle of the ladder. Your previous rank and your hidden MMR still carry weight, which is why two players with the same five results can land in different places. That is also why the rank you finished last season on is the first thing a booster asks about.
The ladder itself uses the same tiers as League of Legends: Iron, Bronze, Silver, Gold, Platinum, Emerald and Diamond, each split into four divisions from IV to I, followed by Master, Grandmaster and Challenger. TFT runs from the League of Legends client and uses the same Riot account, but its ranked rating is completely separate. A high rank on the Rift does not help your TFT placements, and a weak one does not hurt them. Only your own TFT history counts.
Placements matter more than any other five games of the season because they set the starting point for everything that follows. A strong start puts you into lobbies closer to the level you want to play at and leaves fewer divisions to climb. A shaky start, played in a rush on a patch you have not learned yet, can cost weeks of grinding just to get back where you were. Ordering the placements is simply a way to make those first games count.
