LoL Duo Queue Checker: Can You Queue With Your Friend?
This checker applies Riot’s Solo/Duo restriction table to two ranks and tells you whether you can queue together, then shows what Flex allows. The rules are Riot’s: lower tiers can duo across two tiers, Diamond shrinks the window to a few divisions, Master players need to be within 400 LP of each other, and Grandmaster and Challenger queue alone. Flex has no rank limits up to Diamond and only blocks Master-and-above players from partners below Emerald.

LoL Duo Queue Checker
Pick your rank and your friend's rank to see whether Riot's Solo/Duo restrictions let you queue together, and what Flex allows instead.
Riot’s Solo/Duo table
| Your tier | You can queue with |
|---|---|
| Iron | Iron to Silver |
| Bronze | Iron to Silver |
| Silver | Iron to Gold |
| Gold | Silver to Platinum |
| Platinum | Gold to Emerald |
| Emerald | Platinum to Diamond III |
| Diamond IV to Diamond II | Emerald II to Diamond II |
| Diamond I | Diamond III to Master players with less than 200 LP |
| Master | Diamond I (only if the Master player has less than 200 LP) to Master players within 400 LP of each other |
| Grandmaster | Duo not available |
| Challenger | Duo not available |
Three extra rules sit on top of the table. Players with an MMR of Master or higher are solo-only regardless of their visible rank. From Emerald up to Diamond II you cannot queue with a player who has Master-tier MMR while being Diamond or lower. And on KR, nobody can queue with Master or higher tiers. Because MMR is hidden, the client can refuse a duo the table allows; the checker flags this but cannot see your MMR.
Flex queue rules
- No rank restrictions for Diamond and below.
- Master and above can play Flex only with partners who are at least Emerald.
- Party sizes of 1, 2, 3 and 5; a party of 4 is sent to unranked.
- Riot warns that large rank gaps in a Flex party produce harder matchups as the system balances the lobby.
Solo/Duo and Flex ranks are independent and give separate end-of-season rewards. How tiers and divisions work, including the four divisions from Iron to Diamond and the apex tiers, is in our LoL ranks guide; how many games a rank takes is the job of the climb calculator, and the ranked calendar is on season dates.
LoL Duo Queue Checker FAQ
Can a Gold player duo with a Platinum player in LoL?
Yes. Gold can queue with Silver through Platinum in Solo/Duo; any division within those tiers qualifies.
Can Diamond duo with Emerald?
Diamond IV to II can queue with Emerald II and above; Diamond I cannot queue with Emerald at all (its window is Diamond III up to low-LP Master).
Can Master players duo?
Yes, with Diamond I if the Master player has under 200 LP, or with another Master player within 400 LP. Grandmaster and Challenger cannot duo.
Why does the client block a duo that the table allows?
Hidden MMR. Master-or-higher MMR makes a player solo-only, and Emerald to Diamond II players cannot queue with Master-MMR partners.
Are there rank restrictions in Flex?
None for Diamond and below. Master and above need partners of at least Emerald, and parties of four are not allowed.
