The Web Monetization Challenge 2020

The Defold Foundation is inviting web game developers across the world to join the month long Web Monetization game jam.

November 1st 2020 to December 1st 2020

The Defold Foundation is hereby cordially inviting you and your fellow web game developers across the world to join the month long Web Monetization game jam. Developers will be challenged to create a themed web game showing their creative and developer skills as well as a good use of Web Monetization in their games. The proud winner and runner-ups will receive cash prizes, swag and bragging rights!


Theme: Secrets

The theme for the game jam is "Secrets". You must incorporate some aspect of the theme in your game. Perhaps some of the game mechanics are secret and has to be discovered while playing? Or there's a secret weaved into the story, waiting to be uncovered as the game is played? Or maybe the player will find secret treasures? Or something completely different. It is all up to you!


  • You must create an original game for the game jam and you must develop it during the game jam. ⍟
  • You are allowed to use existing tools, frameworks and libraries when creating the game.
  • You are free to use any game engine or framework when creating the game.
  • You must incorporate some aspect of the theme in the game.
  • You must integrate and use Web Monetization in the game.
  • You can create the game on your own or as part of a team.

⍟ = You are allowed to submit the same game to multiple game jams as long as the game was developed during the period of this game jam (a prime example of this is to use the same game for the GitHub GameOff jam and the Web Monetization Challenge jam).

Web Monetization

Web Monetization is an open technology that allows someone viewing a webpage or playing a web game to stream very small payments (micropayments) to the creator in real time. It is an exciting new and non-intrusive way for game developers to monetize their web games while at the same time offering premium content to their paying players.

Web Monetization is being proposed as a W3C standard. It is based on the Interledger protocol which is an open, neutral protocol for transferring money of any currency, including digital currencies such as Bitcoin.


  • 1st place - $1500
  • 2nd place - $750
  • 3rd place - $500
  • 4th-10th place - $100/each

Payment will be made through bank transfer or PayPal. The winner is responsible for paying taxes on the winnings. Bank transfer fees will be paid by the winner.


The submitted games will be judged by a panel of judges. The games will be judged based on three criteria:

  • Fun - Is the game fun?
  • Web Monetization - How well does the game integrate and use Web Monetization?
  • Theme - How well does the game incorporate and interpret the theme?

The winners will be announced two weeks after the game jam has ended. The announcement will be made here, on and on Twitter.


Submissions to this jam should be made using the standard HTML5 game upload process.
