Solo Queue
Ranking up alone, matched with four random teammates instead of a premade team.
Solo queue means entering ranked matchmaking alone rather than with a pre-formed party, getting matched with four random teammates whose communication and coordination can vary wildly game to game. It's widely considered a harder climb than duo or full-squad queue, since a solo player can't control drafting, lane assignment, or in-fight coordination the way a coordinated team can. Because of this, comfort picks and self-sufficient heroes tend to be favored solo-queue picks over heroes that need heavy team setup.
