Toss Mini App Introduction Video
This course is not about how to make games, but rather a course on completing the entire process from "releasing a game to establishing a monetization structure."
I have personally launched 25 HTML5 games on App in Toss.
I am revealing the exact process I went through, from
planning → development → SDK integration → passing inspection → to monetization.
30 million Toss users
Verified user-based platform
Traffic can be secured even without separate marketing
Developers can directly launch and operate it themselves
Toss is a leading platform in South Korea with over 30 million users.
App-in-Toss is an environment created so that
any verified user can directly register and service mini-apps and games within the Toss app.
A platform where you can be instantly exposed to 30 million users.
A structure where developers can directly launch, operate, and generate revenue from their games.
Opportunities like this are rare.

HTML5 games are based on standard web technologies, so they run identically in almost any environment where a browser operates.
It is a structure where creating one allows for utilization across multiple platforms.
Furthermore, JavaScript is one of the languages that generative AI understands best.
It is highly suitable for development using the recently popular Vibe Coding method,
allowing you to quickly implement and experiment with ideas.
🔥 4 Reasons Why HTML5 is Advantageous
Browser-based → Can run on multiple platforms
Easy mobile conversion
JavaScript-based → Great compatibility with Generative AI
Vibe Coding Optimization
: Idea → Rapid Implementation → Immediate Deployment → Feedback Verification available
This course covers the entire process step-by-step, from understanding the structure of HTML5 games to Android packaging and Google Play release, implementing the Appintos-exclusive SDK, applying in-app advertisements, expanding features like leaderboards, and even actual console registration and review submission.
I have personally launched 25 HTML5 games on AppIntos.
👉 How to pass the inspection and where people usually get stuck
👉 Which parts actually impact revenue
I have packed all the trial and error and practical know-how into this course.
Starting with App-in-Toss, more and more companies are paying attention to HTML5 games.
I hope this lecture serves as the starting point that leads to your first launch, first service, and first revenue.

The <From Planning to Launch: Creating and Monetizing Games with AI> webinar I conducted with AppinToss in January 2026 served as the catalyst for me to start this course. I am leaving a link here for those who are interested.
Who is this course right for?
A game planner who wants to upload a game to AppIntos but doesn't know how to get started.
Game developers who want to create web games but don't know how to start
Game developers who want to upload their web games to mobile but don't know how to start
