Umagrid is an unofficial fan project made by a fan, for fans. It's free to play, with no ads and nothing behind a paywall. It is not affiliated with, endorsed by, sponsored by, or otherwise connected to Cygames, Inc. or any other rights holder of Umamusume: Pretty Derby.

Trademarks & artwork

"Umamusume: Pretty Derby," all character names, and all related artwork and trademarks are the property of Cygames, Inc. Character portrait images on this site are sourced from official promotional assets, used purely to help you identify who's who in a fan-made trivia game. They're never sold, and nothing in the game costs money.

Tips

There's a Ko-fi link at the bottom of the game. Tips are completely optional, unlock nothing, and go toward the costs of keeping Umagrid running (the server, the database and the domain). Not tipping changes nothing about the game.

Real-life racing data

A handful of categories dig into the real-life Japanese horse racing history behind these characters — actual race wins, career milestones, that kind of thing. That information comes from public wiki records and is here purely for entertainment and trivia. This site isn't affiliated with the Japan Racing Association (JRA), or any real horses, jockeys, trainers, or owners referenced.

Fan-content guidelines & contact

Umagrid follows Cygames' Fan-Created Content Guidelines. If you're a rights holder, or connected to any of the real horses, owners or races referenced here, and want something changed or taken down, email alphaomega1247@gmail.com and I'll deal with it promptly.

No warranty

This is a hobby project, maintained whenever I get around to it. Puzzle data, descriptions, and character info may have mistakes in them here and there. Nothing here is guaranteed to be accurate, complete, or always up.
