This challenge is an easy and condensed way for you:

1. Build a playable virtual table top game prototype within 6 days.
2. Directly experience the game design process.
3. Learn fundamental playtesting, feedback collection, and iteration techniques.

Here is how it works ↓

I simplified and restructured the prototyping process into a beginner friendly 6 step format where you’ll get

  1. Guiding frameworks
  2. Plug n’ play templates
  3. Examples to reference how other participants.
  4. Practical exercise(s) that can instill a methodical process to build games.


1. You don’t need any coding or scripting skills to participate.

2. The only requirement to participate is to have a “TableTop Simulator”.  We use it in the challenge to build your game and have other people easily playtest it.

⚠️ DISCLAIMER: TableTop Simulator is $20 paid directly to Steam (we are not affiliated with TTS).

If you have completed the challenge (not just watch the video), then I have a 🎁 for you. 

Who is this for?

You play a lot of video games and you had thought of designing games for a living.

You are starting from zero to experience first hand exactly what professional game designers do so you can

  1. Understand the fundamental game making process.
  2. Check if you like doing what game designers do.
  3. Check if you like other core parts of the game dev process: art, programming, production, or QA

You want to get into game design (or other game dev maker positions) professionally.

You know a lot of concepts through consuming Youtube videos and game design posts, but has never built a game or put any concept into practice.

This challenge helps you determine if the game development maker craft is a good fit for your interests and talents and put what you’ve learned into practice.

In the end of the day, game design is a maker’s craft, which means professionally you’re paid to make things.

So if you don’t enjoy making games then this is probably not the profession or hobby you want to invest your time in.
