About the Operator

This page introduces the person who runs the browser game site "UAJ Studio" and explains what the site offers.

Site Overview

Purpose of the Site

UAJ Studio is a site that creates and publishes free-to-play games you can play in a browser alone. No app installation is required. We currently offer the two games below, and we plan to release other games and web apps in the future.

• Typing Battle: a real-time, one-on-one competitive typing game in which you type the prompts shown on screen correctly to whittle down each other's HP.
• Stella Orbs (coming soon): a falling-block puzzle game in which you form a party with constellation spirits and clear the orbs that fall onto a hexagonal board to fight enemies.

Features (Typing Battle)

• Match modes: there are three: Casual Match, Play with Friends (room code), and Ranked Match. Casual Match and matches against friends can be played as a guest without logging in, while Ranked Match requires login (available with Google or an email address).
• Login: an account shared across the site that you can log in to with Google or an email address. You can log in from any page. Once logged in, you can take part in Ranked Match, and your rank points and match record are saved. Services added in the future will also be managed under the same account.
• My Page: after logging in, open My Page from the header menu to change your nickname and check your records for each service, such as Typing Battle and Stella Orbs.
• Match history page: for matches played while logged in, you can check your wins and losses, typing speed, miss rate, rank point progress, and more.
• English mode: a mode in which you type English words as they are. Choose English as the "Prompt language" in the lobby to play it. You can change the display language with the language switcher at the top right of the screen.

All of Typing Battle is free to play. The rules and controls are summarized in the how-to guide. Stella Orbs is a single-player game, and logging in is required to play the stages. Progress, characters, and items are saved to your account. It is free to play (in-game items may be sold; see Terms of Service, Article 12).

Who Runs the Site

The planning, development, and operation of the site are carried out by an individual with the handle "UAJ." Since publishing the first version of Typing Battle on September 17, 2026, we have been adding to it little by little. We do not publish a real name, address, or email address. Please contact us through the feedback page under Contact below.

Update Policy

When we change the games or the site, we publish what changed, why, and how it affects play in the dated update history (patch notes; in Japanese). Our policy is to publish patch notes every time we change the content of a game and release it. Small fixes may be included in a nearby larger update.

About the Numbers We Publish

The numbers shown on pages such as the Stella Orbs data guide and the character profiles (HP, ATK, multipliers, gauges, probabilities, stamina, and so on) are not copied by hand; they are extracted from the actual game's configuration data. When the game's configuration changes, the pages are regenerated. Even so, because of release timing and similar reasons, the pages and the in-game display may occasionally differ. If you notice a discrepancy, please let us know through Feedback.

For First-Time Visitors

The site's highlights and where to find each page are summarized in Getting Around This Site.
