Overview

Umamusume: Pretty Derby (often shortened to simply Umamusume) is a highly popular Japanese mobile gacha game developed and published by Cygames. Officially released in February 2021, the game blends elements of simulation, management, and character collection into a uniquely captivating experience. While the franchise originally began as a multimedia project encompassing anime series, manga, and stage plays, the mobile game stands as its most expansive and enduring pillar.

At its core, Umamusume is a horse racing simulation game, but it applies a radical twist to the traditional sports genre. Instead of actual horses, the characters are "horse girls" (Umamusume)—young women who possess the speed, endurance, and spirits of famous real-world racehorses. They attend the prestigious Tracen Academy, where they compete in high-stakes races with the ultimate goal of winning the Triple Crown and etching their names into history.

The game is available on both iOS and Android platforms, with a highly anticipated PC (DMM Game Player) version that allows for higher graphical fidelity and multiple instances. Over the years, Umamusume has built a massive, dedicated global player base, drawn in by its deep simulation mechanics, high-quality anime-style production values, and surprisingly emotional storytelling.

Gameplay Mechanics

The gameplay of Umamusume is divided into two primary pillars: Training and Racing. These two systems feed into each other, creating a gameplay loop that requires strategic planning, resource management, and a bit of foresight.

The Training Phase

The bulk of the player's time is spent in the training phase, which spans a virtual three-year period representing a horse girl's time at Tracen Academy. Each in-game year is broken down into four turns (representing seasons), and each turn consists of a limited number of Action Points (AP).

During a turn, players allocate AP to various training menus—Speed, Stamina, Power, Guts, and Intelligence. Each stat directly influences a horse girl's performance on the track. Alongside these primary stats, players can choose to train specific Skills (which grant passive or active abilities during races), Heal (to recover physical fatigue), or Rest (to reduce mental stress).

The complexity of the training phase comes from its RNG (Random Number Generation) elements and synergy systems. Training is augmented by Support Cards, a deck of six cards the player builds before starting a scenario. When a training session is selected, Support Cards attached to that stat have a chance to trigger events, granting bonus stat points, skill points (hints), or unique buffs. Triggering multiple Support Card events in a single turn creates massive "explosions" of stats, which is the key to building a top-tier horse girl.

The Racing Phase

At the end of certain turns, the horse girl will participate in a race. Unlike many games where races are simply determined by stats, Umamusume features a partially visualized, strategic race system. Players watch the race unfold from a side-view perspective and must actively manage the horse girl's stamina and positioning.

During a race, players can issue commands to "Push Forward" (moving the horse girl outward to secure a better running line and build urgency) or "Hold Back" (conserving stamina). The most critical mechanic is the Skill Activation system. As the race progresses, a skill gauge fills up. When the conditions are met—such as entering the final straightaway, being in a specific position, or reaching a certain stamina threshold—players can trigger learned skills. Skills might provide a sudden burst of speed, allow the horse girl to break away from the pack, or help her recover stamina in the clutch. Winning races yields Fame, which is necessary to qualify for the endgame races like theURA Finals or the Twilight Combo.

Support Cards & Gacha System

Progression in Umamusume is heavily tied to the acquisition of Support Cards. Players pull these cards from the gacha system using in-game currency or premium crystals. Support cards come in different rarities (R, SR, SSR) and feature various horse girls. An SSR card provides significantly better stats, more potent training buffs, and unique, powerful event chains compared to lower rarities. Building a cohesive "deck" of six Support Cards—balancing stat boosts, skill point generation, and healing—is the primary meta-game for veteran players.

Story & Setting

The world of Umamusume exists in a modern-day alternate reality Japan where the sport of horse racing has been completely reimagined. In this world, the spirits and legacies of legendary real-world racehorses are reincarnated as "horse girls." They possess horse-like physical traits, most notably ears and tails, and exhibit superhuman athletic abilities tailored for sprinting and endurance running. However, outside of the track, they live largely normal lives as students, idols, and everyday young women.

The narrative hub of the game is Tracen Academy (Tokyo Tracen Academy), an elite, sprawling educational institution built specifically to train and nurture horse girls. The academy features state-of-the-art training facilities, dormitories, and its own massive racetrack. Horse girls from all over Japan—and occasionally from overseas—enroll here with the dream of making it to the big leagues.

Players assume the role of a Trainer, a specialized coach assigned to guide these horse girls. The game’s Main Story (Scenario) initially follows the player as they are recruited to Tracen Academy and paired with Special Week, a cheerful, hardworking horse girl from the countryside who dreams of becoming the best in Japan, just like her mother (the legendary racehorse, Sunday Silence). Together, they navigate the rigorous environment of the academy, form rivalries, and forge unbreakable bonds.

As the game has expanded, Cygames has introduced entirely new story scenarios. These "A" and "B" scenarios shift the focus away from Special Week, placing the trainer in different departments of the academy or entirely new narrative situations, allowing players to experience the lore and growth of different subsets of characters without repeating the original storyline.

Key Features

Deep Simulation Mechanics: Far from a simple clicker, Umamusume offers a robust management sim requiring players to balance stats, stamina, stress, and skill acquisition over a multi-year in-game timeline.
Unique "Horse Girl" Concept: The ingenious fusion of real-world horse racing history with anime idol culture creates a fresh, highly appealing aesthetic and character dynamic.

Rich Historical Homage: The characters, their racing styles, and their signature colors are directly inspired by actual famous racehorses (such as Silence Suzuka, Vodka, and Symboli Rudolf), making the game surprisingly educational for racing enthusiasts.
Extensive Customization: Beyond racing, players can unlock hundreds of outfits, accessories, and living space decorations for their horse girls, allowing for deep personalization in the "Live" viewer mode.
High-Quality Audio and Voice Acting: The game features a massive roster of top-tier Japanese voice actors who record unique lines for training events, race commentary, victory screens, and casual dorm conversations.

Tips for Beginners

Starting Umamusume can feel incredibly overwhelming due to the sheer number of menus, stats, and unskippable tutorials. Here are some practical tips to help you survive your first few weeks as a Trainer:

Focus on a Single Team: Early on, you will be prompted to choose one of three teams (Team Spica, Team Rigil, or Team Canopus). Stick with the one you pick. Trying to split your early resources across multiple teams will severely slow down your progress. Team Spica is generally recommended for beginners due to its straightforward gameplay buffs.
Rely on Friend Support Cards: As a new player, your gacha-pulled Support Cards will be weak. Bypass this by borrowing SSR Support Cards from your in-game friends or from the global ranking list. A full deck of borrowed SSR cards will carry you through your early training runs until you build your own roster.
Do Not Sell Duplicate Cards Immediately: When you pull a duplicate SSR Support Card, do not use it for "Kizuna Points" right away. Instead, limit break the card to level 50 first. You can extract the Kizuna Points later if needed, but limit breaking it provides an immediate, massive power boost to the card's training capabilities.
Understand the "Winning Live" Requirements: To get the best ending in a training scenario (the Winning Live concert), you must collect a specific number of "Fans" and win certain target races. Plan your race schedule carefully; entering too many small races can burn out your horse girl's stamina, while skipping too many will leave you short of the Fan requirement for the URA Finals.
Learn to Read Skill Hint Levels: When training, Support Cards will occasionally drop "Hints" for specific skills. A gold hint means you can learn the skill for fewer points; a pink/red hint means even fewer. Never learn a skill from the base menu if you can wait to get a hint for it first, as saving Skill Points (Pt) is crucial for acquiring high-tier, race-winning skills.
Prioritize Stamina and Speed: While all five stats are important, Speed and Stamina are the foundational pillars of any successful horse girl. If a horse girl runs out of stamina before the final stretch, no amount of Power or Guts will save her from falling behind. Build a solid base of Speed and Stamina before heavily investing in the other stats.
Embrace Failure: You will fail your first few training runs. You will run out of stamina, your horse girl will get injured, or you will lose the final race. This is entirely normal. Umamusume is a game of trial and error. Each failure teaches you how to manage the RNG better and how specific Support card synergies actually function in practice.

FAQ

Is Umamusume available in English?

Officially, there is no global English version of the game; the primary server is Japanese. However, the game features an incredibly robust, community-translated English patch built directly into the game engine. By simply switching your game's text language to English in the settings menu, you can play the entire game—including all main stories, events, and tutorials—in high-quality English. The voice acting remains in Japanese.

Is Umamusume a "pay-to-win" game?

Umamusume is widely considered one of the most "free-to-play friendly" gacha games on the market. While spending money allows you to obtain high-tier Support Cards faster, the actual gameplay is a PvE simulation. Having the best cards does not guarantee a win if the player does not understand the training mechanics. A skilled player with a fully leveled team of free SSR cards can easily achieve top-tier results that match or exceed those of a paying player. The gacha is generous, and the game provides ample free premium currency through events and login bonuses.

Do I need to know about real horse racing to enjoy the game?

Not at all. While the game is deeply intertwined with real-world Japanese horse racing history—featuring homages to horses like Symboli Rudolf, Oguri Cap, and Tokai Teio—you do not need any prior knowledge of the sport to enjoy it. The game teaches you the mechanics of its own racing system from the ground up. However, learning about the real-world counterparts often adds a layer of emotional weight to the stories, making the game even more enjoyable for those who choose to look up the history.

What is the difference between the Mobile and PC versions?

Gameplay-wise, the Mobile (iOS/Android) and PC (DMM Game Player) versions are 100% identical. They share the same servers, and your progress carries over seamlessly between them. The primary difference is performance. The PC version allows for higher resolution rendering, uncapped frame rates, and significantly faster load times. Furthermore, the PC version is highly recommended for players who want to run multiple accounts or use macro tools, as it handles multi-instance management much better than mobile emulators.

How long does it take to complete a training run?

A single standard training run takes about 30 to 45 minutes of active playtime. However, because the game involves a lot of reading through event dialogue, watching race visualizations, and managing menus, a run can take up to an hour if you take your time. If you are highly experienced and skipping dialogue, you can "speedrun" a training session in about 20 minutes. Fortunately, the game includes a built-in auto-skip feature for repeated dialogues, making subsequent runs much faster than your first.
