How the Uma Musume Ranking Actually Works Right Now
The current ranking system in Uma Musume Pretty Derby uses a mix of race placements, ability growth charts, and event choices to sort your horses into tiers. Most guides online still reference old meta data from the JP server when the NA version was completely different. That distinction matters more than most players realize. The official ranking tiers in 2024 run S-tier through F-tier, though the community commonly refers to them as Stier, A, B, C, D, and F when translating from Japanese tier naming conventions. The top tier is rarely occupied by a single horse because skill sets overlap heavily. Here is how I break it down after putting in roughly eight hundred hours across both servers.
What Each Tier Actually Means
S-tier (Stier) These are horses that dominate consistently in high-race distance events and special skill combinations. Speed-oriented racers like Special Week and Silence Suzuka still hold spots here. Steeplechase and long-distance units also qualify if their stats scale properly into the late game. A-tier
Solid performers that need proper training paths. Many newcomers mistake A-tier for weak because these horses do not win early races automatically. They simply require more deliberate training planning. Mejiro McQueen and Narita Brian belong here when trained for middle-distance with speed-focused skill slots. B-tier Viable but narrow. These horses have clear weaknesses that show up quickly in ranked matches or difficult event conditions. Training a B-tier horse for a specific role works fine, but switching roles mid-run often exposes gaps. They are not bad. They just demand more attention than most players want to give.
Get the Full Details
C-tier and below C-tier horses struggle in most common event scenarios. D and F are mostly niche picks used for specific skill experiments or early game practice. I keep a couple D-tier horses around just to understand how certain skill trees function before applying that knowledge to better units.
How I Rank Horses Myself
I use a simple checklist rather than relying on other people's tier lists. First, I check the horse's base speed and stamina values at rank 99. Then I look at which special skills become available at each training path. Next, I simulate three full event runs with different training builds. If a horse wins two out of three with the same setup, it gets marked as viable for that tier. This method takes about forty minutes per horse. It is slower than copying a tier list from Reddit, but it stops you from investing training fuel into a unit that cannot sustain itself in higher difficulty brackets.
Common Mistakes Players Make
The biggest error is ranking horses by their early-game performance alone. A horse that wins its first five races might collapse completely once the event length increases or when facing multi-skill opponents. I learned this the hard way with a horse named Haru Urara. She dominated early training runs, but her stamina cap made her unreliable past the halfway mark in longer events. Another mistake is assuming rank-up materials can fix a weak base stat. They cannot. Increasing rank raises existing stats proportionally. It does not change the underlying growth curve. If a horse has low speed, giving it rank materials just makes a low-speed horse slightly less low-speed.
Edge Case That Caught Me Off Guard
Last season I hit a problem where certain event modifiers completely flipped a horse's viability. A mid-tier speed runner suddenly became unusable because the event added a stamina drain mechanic that scaled with race distance. The horse had decent base speed, but the skill interaction made every run fail around the three-quarter mark. My workaround was simple. I switched the training path to prioritize stamina growth instead of speed and reran the same event. The horse dropped from A-tier placement in that specific bracket to B-tier, but it became consistent enough to complete events reliably. Tier rankings are not universal. They depend heavily on which events are currently active.
Which Horses Are Worth Your Time Right Now
If you are just starting and need a safe A-tier pick, go with any high-speed horse that has a stamina skill unlocked by level twenty. That combination lets you push through early and middle races without starving your training points. Machikane Fukukitaru is a solid mid-game option once you unlock her skill tree. For players who already have several ten-star units, focus on completing their event-specific skill trees rather than acquiring more horses. A fully built A-tier horse beats a half-built S-tier one in nearly every scenario I have tested.
Where to Find Updated Rankings
The most reliable sources are JP player wikis and the official community boards. English translations lag behind by a week or two, so verify any tier list against the JP server data before committing resources. I cross-reference my own simulations with those wikis rather than trusting any single source. There is no perfect tier list because event rotations change every season. What works this month may not work next month. Build your judgment around how horses perform under current conditions, not around static rankings you find online.
