MMR (Matchmaking Rating) is calculated based on wins/losses, individual performance, and rank difference between teams. To improve it: maintain a >55% win rate, play consistently, avoid tilt, and focus on mastering 2-3 champions or agents.

Key strategies include: mastering 2-3 champions at an expert level, understanding the current meta, communicating effectively with your team, tracking enemy cooldowns, and reviewing your replays to identify recurring mistakes.

For optimal duo synergy: choose complementary roles (e.g., jungle+mid), communicate constantly via voice chat, synchronize objective timings, and adapt your picks to create powerful combos.

At Platinum+ ranks, boosters must be at least Master/Grandmaster with a proven 60%+ win rate. For Immortal/Radiant: top 500 players with competitive experience. All pass skill tests and background checks. Average booster rating: 4.8/5.

MMR decay varies by game. Most titles reduce your visible rank after 14-28 days of inactivity, but hidden MMR stays intact. After returning, you may need 5-10 games to recalibrate. We recommend maintenance boosts if you anticipate long breaks.
