What You’ll Learn
How Our MMR Checker Actually Works
I’ve been tracking my MMR since Season 3. Here’s what actually matters when checking your matchmaking rating:
The Formula Behind Every MMR Checker
- Win/Loss ratio from your last 30-50 ranked games (not normals)
- LP changes — the difference between gains and losses tells everything
- Lobby ranks — playing with Plat players while you’re Gold? Your MMR is climbing
- Win streaks — 5+ wins in a row boost your rating faster than random wins
- Queue type — Solo/Duo and Flex have completely separate ratings
Pro tip from a Master player: Check your MMR after every promo. That’s when the system recalibrates hardest.
LP Gains Tell Your MMR Story
Forget what streamers say. Your LP changes reveal your exact MMR situation:
Real example: My friend was hardstuck Gold 2 with +13/-22 LP. Used our mmr checker, found his MMR was Silver 1. He dodged promos twice (loses LP, not MMR), went on a 7-game winstreak, and now gets +19/-17. Still Gold 2, but climbing fast.
MMR Checker Results from Real Players
Case 1: The Smurf Detection
Fresh account, 10-0 in placements. MMR Checker shows: Plat 2 MMR while placed in Silver 1. Gets +35 LP per win, skips Gold 3 and Gold 1 entirely. This is Riot’s smurf queue working.
Case 2: The Decayed Master
Didn’t play for 3 months, decayed to Diamond 2. MMR Checker shows: Still Master tier MMR. First game back: +31 LP. The mmr checker lol caught what the visible rank missed.
Case 3: The Tilted Grinder
500 games, 48% winrate, hardstuck Plat 4. MMR Checker shows: Gold 2 MMR. Every loss is -24 LP. Solution? New account reached Plat 2 in 60 games.
What Changed in 2025 Season
Riot tweaked the system. Here’s what’s different:
- 5 placement games instead of 10 — your MMR adjusts faster
- Emerald tier shifted everyone’s MMR — old Plat 1 is now Emerald 4
- Three splits per season — soft MMR reset every 4 months
- No more inter-queue MMR influence — Flex games don’t affect Solo/Duo at all
- Apex decay hits harder — Masters lose 75 LP daily without banking
- Smurf queue triggers faster — 70%+ winrate puts you with other smurfs by game 15
Riot’s official MMR explanation confirms these changes, but our mmr checker gives you the numbers they won’t.
How to Fix Your MMR (Without Buying Boosts)
The Winstreak Method
Win 5+ games in a row. Sounds simple? Here’s the trick: play your absolute best champion only. My MMR jumped from Gold 1 to Plat 3 equivalent after a 9-game Jinx streak.
The Dodge Strategy
Dodge bad lobbies (autofilled jungler, 30% winrate Yasuo). You lose 3 LP first dodge, 10 LP second, but zero MMR loss. Use our mmr checker before and after — number stays the same.
The Fresh Start
Sometimes your MMR is too damaged. 800+ games with 49% winrate? New account hits your true rank in 50 games instead of grinding 200+ on the old one.
The Duo Abuse
Duo with someone exactly one tier below you. You face easier opponents but gain normal MMR. Just don’t duo with someone at your rank with bad MMR — it’s contagious.
MMR Myths That Keep You Hardstuck
❌ Myth: “Normal games affect ranked MMR”
Truth: Completely separate. You can be Challenger in normals, Iron in ranked. Only exception: brand new accounts use normal MMR for first placement.
❌ Myth: “Remake games hurt MMR”
Truth: Remakes don’t touch MMR or count as games played. Free dodge basically.
❌ Myth: “KDA affects MMR gains”
Truth: Only wins and losses matter. You can go 0/10/0 and gain the same MMR as going 10/0/10 if you win.
❌ Myth: “MMR checker sites are fake”
Truth: Good ones like ours use the same math Riot does. We reverse-engineer from LP gains and lobby averages. It’s 85-90% accurate.
MMR Checker FAQ – Real Questions from Players
How accurate is this mmr checker?
About 85-90% accurate after 30+ ranked games. We use the same signals Riot’s system uses: LP changes, win patterns, and lobby ranks. The more games, the more accurate.
Why does my friend gain more LP in the same game?
Different MMR. Even at the same rank, your hidden ratings differ. Use the mmr checker lol for both accounts and you’ll see the gap.
Can I check someone else’s MMR?
Yes, if their profile is public. Just need their summoner name and region. Works for any account from Iron to Challenger.
Does the mmr checker work for all regions?
Yes. EUW, EUNE, NA, KR, BR, TR, LAN, LAS, OCE, RU, JP — all servers supported. Percentiles adjust per region (Korean Diamond = NA Master basically).
How often should I check my MMR?
Every 20-30 games or after big win/loss streaks. Daily checking is pointless — MMR moves slowly unless you’re streaking hard.
Is 1500 MMR good?
That’s around Gold 4. Average player is Silver 2 (1350 MMR), so you’re above average. Top 10% starts at Plat 4 (1800 MMR).

The Bottom Line on MMR
Your MMR is the only number that matters in League. Rank is just a shiny badge. Use our mmr checker lol to see the truth, then fix your rating with the strategies above. Stop grinding hundreds of games at bad MMR. Work smarter.
Remember: The system wants you at 50% winrate. Beat it by understanding it.
