Say you win a game and take 17 LP, then drop 22 in the next one. Your lane opponent, at the exact same rank, takes 28 and drops 12. It isn't a client bug and it isn't bad luck: the system is telling you something specific about where it thinks you belong. The League of Legends ladder runs on two numbers, and you only ever see one of them. This guide explains the second, with values taken from official Riot sources current as of patch 26.18, except the one we flag explicitly as a community observation.
The number you see and the number that decides
LP (League Points, the points that appear under your rank in your profile) are the visible part: they go up when you win, down when you lose, and at 100 they promote you. They're a position, not a verdict.
The verdict is MMR (Matchmaking Rating, the hidden matchmaking score). Riot defines it like this: it's what determines your place on the ladder and matches you with players of similar skill; it goes up when you win and down when you lose. It's the only number the system actually uses to build games.
You'll never see it. That's a choice Riot has stated openly: it calls MMR a secret, and explains that showing it outside its context would make it a less useful indicator of skill, not a more useful one. The closest thing is the Climb Indicator introduced in 2026, a note on the loading screen flagging which players in the lobby have a rank that has fallen behind their MMR, teammates included. It's there to size up who you're playing with, not to read your own score.
Ten tiers, four divisions, a hundred points
The ladder has ten steps: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Master, Grandmaster, Challenger. From Iron to Diamond every tier has four divisions, numbered backwards: IV is the lowest, I is the highest. The three steps at the top, known as the apex tiers, have no divisions: they're a single continuous ranking.
There are two permanent ranked queues, Solo/Duo and Flex, and they should be treated as two independent ladders: rank, hidden score, and rewards don't talk to each other. With one clarification: since patch 26.01 the system also uses your Solo/Duo rank as context when forming Flex games.
At 100 LP you jump to the next division and the excess points carry over, so nothing is wasted. At 100 LP in division I you move straight up to the tier above, with no extra test: the old promotion series were removed in two stages, the ones between divisions in November 2020 and the ones between tiers in July 2023. If someone still tells you about "winning two out of three to move up a division," they're describing a game that stopped existing back then.
Going down works the other way around: it happens when a loss takes more LP than you have, so at 5 LP in Silver III a 20-point loss leaves you in Silver IV with 85. Between one tier and the next, though, there's protection, and when the demotion does come you're placed at 25, 50, or 75 LP, depending on how much distance the system sees between your real level and the rank you're showing. Dropping a tier always puts you in the highest division of the one below, so Gold IV takes you to Silver I, not Silver IV.
Why you take 17 and drop 22
This is the heart of it. Riot describes three situations, and the LP number you see at the end of a game tells you which one you're in.
- Similar gains and losses. If you take roughly as many points as you give back, MMR and rank line up: the system thinks the rank you're showing is the right one. The reference figure the community observes in this state is 20 points per game, but be careful: Riot has never published it, unlike the apex figure we come to further down. Since patch 26.01 that figure is the same for every tier up to and including Diamond, whereas before that players below Emerald took and lost 25.
- Big gains, small losses. Your MMR is appreciably higher than your visible rank, and the system, in Riot's own words, tries to push you toward the position you belong in with bigger gains when you win and smaller losses when you lose. That's what's happening to the player taking 28 and dropping 12.
- Small gains, big losses. The opposite scenario, and it almost always comes from a losing streak: the system reads rank and MMR as no longer aligned and takes more away with every game you drop, until your win rate settles.
That asymmetric spread isn't a punishment, it's a diagnosis. A +28 says your rank sits below your real level and the system is trying to correct it quickly; a +17 next to a -22 says the opposite, that the rank you're showing is higher than your recent play supports. Reading those two numbers is reading the game's opinion of you.
Riot describes the mechanism that speeds up players who have fallen behind, but it has no official name: "LP catch-up" is a phrase that came from players, not a Riot term.
No, your KDA doesn't raise your MMR
It's the single most widespread belief, and KDA (kills, deaths, and assists, the summary the client shows at the end of a game) has nothing to do with it. The official position, restated over the years, is that Riot doesn't want to judge players on individual performance, because the best way to beat a system like that would be to pad your own stats instead of helping the team win. The practical consequence is that the end-of-game scoreboard is not an ingredient of the hidden score that decides your games.
There's one exception worth knowing, because it touches LP and not MMR. It's called the Aegis of Valor, new in 2026: it rewards players who play a role they didn't ask for, meaning on autofill, automatically assigned to a role they hadn't selected. At a rate Riot calls comparable, it also reaches players who pick Fill, the option that hands the choice of role to the system, and players who consistently play the least requested roles, support and jungle. It doesn't trigger every game: Riot describes it as an occasional bonus, not an entitlement.
In the year's first two seasons it required a certain mastery grade, the letter from D to S the client assigns at the end of a game, and in exchange the Aegis also protected you on a loss. Since Season 3, which began on July 29, 2026, all that's left is doubled LP on a win, with no performance requirement at all. Careful if you go and check: some Riot support pages haven't been updated to Season 3 yet and still describe the previous version, the one with loss protection.
So today the end-of-game scoreboard, the one everybody screenshots to prove they played well, doesn't move a single point. It's still worth going back over, but for the reasons set out in the method for reviewing your own games, not because the system looks at it.
The other things that cost you LP
Besides losses, three things move the counter, and almost nobody has the right numbers for them.
- The dodge, meaning leaving champion select before the game starts. The first one costs 6 minutes of waiting and 5 LP, the second 30 minutes and 15 LP, the third and beyond 12 hours and 15 LP. In the apex tiers the price rises to 20 LP and touches MMR as well, and Riot describes it elsewhere as the equivalent of a full loss. The figures of 3 and 10 points that still circulate, kept alive by a few pages nobody ever updated, date back several years and no longer apply.
- Leaving a game, or going inactive in one. The main punishment is a forced wait before you can queue again, from one minute to a quarter of an hour; in repeat cases it applies across five games in a row and can turn into a lockout of 24 hours to two weeks. But Riot also states there's an LP reduction, which applies on wins as well as losses and carries over into the games that follow. The exact size has never been published, and points lost that way are not given back.
- Compensation, which does exist and runs the other way. Consolation LP gives back the points from a loss in which a teammate outside your premade, meaning not one of the friends you queued with, is confirmed as absent or as a griefer. You have to have actually lost points, though, so anyone sitting at 0 LP in division IV of their tier gets nothing, and there's a weekly cap. Loss Prevented only kicks in for platform problems: in that case you lose neither LP nor MMR, and in roughly half of them the game is still counted as a win, with reduced gains.
One punishment that has gone: until February 2026, players who behaved badly could be barred from ranked games for a period, while staying free to play normals. Since patch 26.04 that penalty is no longer applied, and what's left are the forced waits before you can queue again and account suspensions.
Placements matter less than you think
Placement games happen in two cases only: the first time you ever play ranked, and at the start of each year. There are five per queue, not the ten many people remember. They don't cost LP, so a loss is worth zero and doesn't move you backwards, but leaving a game counts as a loss. The highest you can land at the end of the five is Diamond III: above that you have to climb normally.
Watch out for a common misreading, though. The fact that you don't lose LP doesn't make those games free: Riot is explicit that every win and every loss moves MMR during placements too.
A new account doesn't start from nothing either. If you've never played a ranked queue, the system takes its starting point from your normal games: both your Swiftplay MMR and your Normal Draft MMR count, two of the client's non-ranked modes. From the following year onward, what counts most is where you finished. To get into ranked you need level 30, twenty champions owned, and ten normal games on Summoner's Rift, the classic five-versus-five map.
Still, five games weigh little against the fifty that follow: putting off your placements for weeks while you wait to be in form is optimizing the wrong thing.
Above Diamond the system really does change
Master, Grandmaster, and Challenger don't work like the rest of the ladder. They're a single ranking on cumulative LP, with no divisions and no ceiling: you can sit at 300 points or at 1,000 and beyond. You enter Master with the usual 100 LP from Diamond I, but Grandmaster takes 400 LP and you have to hold more than the last Grandmaster in your region; Challenger takes 800, on the same condition. Those are the thresholds Riot's support page lists today; the April 2026 announcement, though, tied them to the six reset regions only, so elsewhere it's worth checking in the client. The places are capped in any case: in each of EUW, Korea, NA, and Southeast Asia there are 700 Grandmaster spots and 300 Challenger spots.
Those thresholds changed recently. Up to patch 26.09 the Challenger threshold was 500, as Riot itself noted when announcing the change, and the Grandmaster one sat at 200. They were raised alongside a rare intervention: on April 29, 2026, every Master, Grandmaster, and Challenger in NA, EUW, EUNE, Brazil, LAN, and Turkey was put back to Master at 0 LP, with both the visible rank and the MMR wiped. In the other regions it didn't happen.
From Diamond up there's also decay, the LP you lose for not playing. In Diamond every game banks 7 days of credit, up to a maximum of 28, and 28 is what you find already credited the moment you arrive in the tier; when the credit runs out, each day of inactivity costs 50 LP. In the apex tiers the pace is much harsher: one day per game, 14 maximum, and 75 LP a day. Anyone who hits zero drops a division, and from the apex tiers lands in Diamond II.
One last thing about LP up there. Since 26.09 the baseline in the apex tiers has moved to 30 points, with an expected spread between +35/-25 and +25/-35: it's the answer to a problem Riot had acknowledged in March 2026, when it admitted to seeing plenty of +10 and -30 cases in that bracket; in April it said it considered the issue resolved by the matchmaking improvements in patch 26.06.
The start-of-year reset, and what doesn't reset
2026 has three seasons inside a single yearly cycle: For Demacia from 26.01, Pandemonium from 26.09, Classic from 26.15. Each has its own Victorious skin, earned with fifteen wins in a ranked queue, and the win count starts over with every season. The wins alone aren't enough, though: to actually receive the reward you have to be at least Honor level 3, so behavior penalties cost you here too.
The real reset is yearly, not seasonal, and it changes little more than the window dressing. The visible rank drops by roughly a full tier from where you finished, with a re-entry ceiling of Emerald I for anyone coming from higher up. MMR, on the other hand, stays where it was: that holds for everyone up to and including Diamond, while at the top of the ladder Riot compresses the values at every restart and, in exceptional cases like April 2026, wipes them. That's why in January, for weeks, you gain far more points than you lose: you didn't get stronger over the holidays, it's your rank closing the distance to an MMR that never moved. Read those numbers as a promotion you earned and you're lining up a disappointment for February.
What the system doesn't do
Three deeply rooted beliefs, all of them refutable without resorting to opinion.
- "It puts trolls on my team to drag me back to 50%." The official answer is blunt: there is nothing in the MMR system that forces less skilled teammates or disproportionately stronger opponents on you. The 50% is real, but it's the target of a balanced game, meaning two teams with the same chance of winning, not a correction applied to you personally.
- "My MMR is 1,850." No MMR value appears in the client or in any public interface: the numbers you read on stat tracking sites are estimates worked out by third parties. The formulas aren't public either, and the old Elo system, the scoring method borrowed from chess that the game used in its early days, has been out of use since 2013.
- "Smurfs get spotted right away." A smurf is the secondary account of an already strong player, opened to play in a lower bracket. A detection system does exist, but in 2024 Riot admitted those accounts were taking too long to reach their real level, and has said since then that it's working on it. It's a known limitation, not a theory.
And duo, since the question always comes up: Riot states that playing as a pair brings advantages the system accounts for, meaning slightly tougher opponents or reduced LP gains. The rank gap allowed between the two players narrows the higher you go, and in Grandmaster and Challenger duo isn't available.
What to do with this, in practice
Reading your LP means different things depending on where you play, and it's worth being honest about that.
- From Iron to Gold the points are almost pure noise: the distance to your real rank closes with fundamentals, and minions per minute together with avoidable deaths explain nearly all of it, as the CS guide shows.
- From Platinum to Diamond the spread becomes informative: if you consistently gain more than you lose, the system is telling you your MMR is ahead of your rank, and that's the moment to play as much as you can instead of stopping for fear of ruining the win streak.
- If you lose more than you gain for many games in a row, the message is the opposite, and you don't get around it by playing more: something in the way you play has to change, one correction at a time.
The rule that sums it all up: you don't read one game, you read thirty. A single +17 means nothing; thirty games with gains always below losses mean a great deal. And if the losing streak is costing you clarity before it costs you points, that's the problem to solve first, and it's the subject of how to stop tilting. The rest of the climb, from champion picks to managing your time, is in the complete ranked guide, while the terms you've run into here and elsewhere are collected in the League of Legends glossary.
The values on this page will change again with every patch: what doesn't change is that the hidden score measures one thing only, whether your team wins, and that the only way to move it is to make better decisions while you play, which is exactly when LoL Sensei works with you.
