You're in Discord, ready to climb, and the client throws you "rank disparity too high" the second you hit Find Match. The rules around who can play together changed meaningfully in 2026, and most older guides on the topic are now wrong on at least one major point. Here's the current breakdown pulled straight from Riot's Ranked Tiers, Divisions, and Queues page.
Why These Restrictions Exist
Solo/Duo restricts party rank gaps to keep boosting in check and keep matches close in skill. Each queue has its own ladder and its own rules. Solo/Duo is the strict one. Flex bends most of the rules. Clash ignores them entirely.
Solo/Duo Queue Rules
Each rank has its own fixed range, not a blanket "+/-N tiers" rule that older guides invented. Riot's official table:
| Your Rank | Can queue with |
|---|---|
| Iron | Iron - Silver |
| Bronze | Iron - Silver |
| Silver | Iron - Gold |
| Gold | Silver - Platinum |
| Platinum | Gold - Emerald |
| Emerald | Platinum - Diamond III |
| Diamond IV - Diamond II | Emerald II - Diamond II |
| Diamond I | Diamond III - Master |
| Master | Diamond I - Grandmaster |
| Grandmaster | Master - Challenger |
| Challenger | Grandmaster - Challenger |
A few practical reads of this table. Iron has the widest reach upward because nothing sits below it, so an Iron player can queue with anyone Iron through Silver. Bronze and Silver tighten in compared to what older guides suggested. Bronze does not stretch up to Gold, and Silver does not stretch all the way to Platinum, regardless of what some AI generic guide somewhere on the internet might claim.
The Emerald and Diamond rows are where most confusion happens. Emerald (any division) can queue with anyone from Platinum through Diamond III, which is a wider range than the "two divisions either way" rule a lot of guides made up. Diamond IV through Diamond II share the same range, Emerald II up to Diamond II. Diamond I gets its own line and can queue all the way up to Master.
Master, Grandmaster, and Challenger Can Duo Again
If you stopped following Apex tier years ago when Riot pulled duo queue, here's the news. Patch 26.01 in January 2026 brought it back. Master can queue with Diamond I through Grandmaster. Grandmaster can queue with Master through Challenger. Challenger can queue with Grandmaster or Challenger. The pro-vs-pro duo concern is a real possibility again outside Korea.
Korea is the only regional carve-out. KR servers keep Master and above as solo-only, which is why pro Korean players still cannot duo on the live ladder. Other regions follow the global rules per Riot's documentation.
MMR Restrictions Layered on Top
Visible rank is one filter. Hidden MMR is another. Riot adds three MMR-based rules on top of the table above.
If you're Emerald through Diamond II, you cannot queue with someone whose MMR is at Master tier while their visible rank is Diamond or below. That stops smurfs with inflated MMR from dragging boosted lobbies through duo. If you're Diamond I, you cannot queue with someone holding Grandmaster MMR while their visible rank is Diamond or Master. And if your own MMR is Master tier or higher, you're solo-only no matter what your visible rank says.

Flex Queue Bends Most Rules
Flex uses different MMR and a different set of restrictions. For everyone Diamond and below there are zero rank gaps to worry about. You can queue an Iron 4 with a Diamond 1 if you really want to, the matchmaker will figure it out (badly).
Two restrictions stick. If anyone in your party is Master or higher, every other player has to be Emerald or higher. And four player parties are blocked across the board, no exceptions. You can queue solo, as a duo, as a trio, or as a full five stack, but never as a four. That rule exists to protect the random fifth player from getting bullied by a coordinated four stack.
Clash Doesn't Care About Solo/Duo Restrictions
Clash uses your Solo/Duo rank to seed your team into a Clash tier (Tier I sweatfest down to Tier IV casual), but it does not restrict who can be on your team. You need exactly five players, each at level 30, with ranked placements done and SMS verification on the account. Beyond that, your team can mix any ranks. The matchmaker pairs you against teams of similar averaged rank, so a stacked team mostly faces other stacked teams.
Decay Numbers (And One Common Myth)
A myth from older guides: Master players who decay back to Diamond regain duo privileges. Two reasons that no longer applies. Apex players can already duo as of Patch 26.01, so there's no privilege to recover. And the actual decay numbers older guides cite were wrong anyway.
The real 2026 decay rules. Diamond accounts get 28 inactive days before LP starts dropping, then lose 50 LP per day, with demotion staying inside Diamond unless you fall below Diamond IV. Master, Grandmaster, and Challenger get 14 inactive days, then lose 75 LP per day, and a fully decayed Master account drops into Diamond II rather than Diamond I.
What Changed in 2026
Patch 26.01 reopened duo queue at Master, Grandmaster, and Challenger outside Korea, after roughly five years of solo-only at the top. Riot tightened Apex dodge rules at the same time to keep the new duo system from getting abused. A dodge at Master and above now counts as a full loss with MMR impact, not the small LP penalty lower ranks pay. Autofill status also carries over across dodges instead of resetting. Full breakdown of those rules in our LoL Dodge guide.
Quick Reference
- Iron, Bronze: queue with Iron through Silver
- Silver: Iron through Gold
- Gold, Platinum: one tier in either direction
- Emerald: Platinum through Diamond III
- Diamond IV-II: Emerald II through Diamond II
- Diamond I: Diamond III through Master
- Master, Grandmaster, Challenger: duo allowed within their range outside Korea
- Flex: no rank rules below Master+, no four player parties, Master+ requires Emerald+ teammates
- Clash: any ranks allowed on the same team, tier seeded by Solo/Duo rank
