Toss Mini App Introduction Video

Showcase your game
to Toss's 30 million users.

Launch HTML5 games on App-in-Toss and monetize them (+Simultaneous Android distribution)

“I’ve made a game, but where do I upload it?”
“How do I generate revenue?”

This course is not about how to make games, but rather a course on completing the entire structure of 'releasing games and making money.'

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.

Why now, App in Toss?

30 million Toss users

Platform based on authenticated users

Acquire traffic without separate marketing

Developers can directly launch and operate it themselves

Toss is South Korea's leading platform with over 30 million users.
App-in-Toss is an environment created within the Toss app so that
any verified user can directly register and provide services for mini-apps and games.


A platform that can provide instant exposure to 30 million users.
A structure where developers can directly launch, operate, and generate revenue from their games.
Opportunities like this are rare.

Example Game (Successfully launched on Toss)

In this lecture, we will build based on
HTML5.

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 your ideas.

🔥 4 Reasons Why HTML5 is Advantageous

  • Browser-based → Executable on multiple platforms

  • Easy mobile conversion

  • JavaScript-based → Great compatibility with Generative AI

  • Vibe coding optimization
    : Idea → Fast implementation → Immediate deployment → Instant feedback check

What you will learn in this course

In this course, we will cover the entire process step-by-step, from understanding the structure of HTML5 games to Android packaging and Google Play publishing, implementing the Appintos-exclusive SDK, applying in-app advertisements, expanding features like leaderboards, and finally, actual console registration and review submission.


This course doesn't just end at "How do I make a game?"

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.

The experience of your first launch is

It will be a much bigger level-up than you expect.

Starting with Apps 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, your first service, and your first revenue.

The instructor's game (Launched on Toss)

I started this lecture following the Toss webinar in January 2026.

The webinar that 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.
