RankedTiers is a competitive Minecraft PvP server built around ranked 1v1 matches, ELO-based skill rankings, and monthly seasons. You can jump into 8 ranked kits, including Sword, Axe, Diamond Pot, Cart PvP, and four progression formats: Early Game, Mid Game / Diamond SMP, Late Game / Spear & Mace, and End Game / Crystal PvP. The goal is simple: grind your way up the ladder from Bronze to Godlike, with 3 sub-levels in each tier.
There are per-kit leaderboards, clans with tags and colors, a VS AI training mode, a custom kit editor, parties, friends, and spectate mode for watching matches. It is free to play, and both Java and Bedrock are supported through GeyserMC, so players on all Minecraft versions from 1.8.x to 1.21.x can join in.
