Awards Ceremony

DevGAMM in Minsk, Belarus (November 16-17) is a fun place to get together for a group selfie after the jam

  • Yes, most stuff around DevGAMM is in Russian, but the organizers try hard to help everyone feel welcome, and Belarus has waived visas recently. Now you have 2.5 reasons to visit the city where World of Tanks was born!
  • We will host the #CoronaDefoldJam awards ceremony on the main stage at DevGAMM, where Corona and Defold will give away small nice prizes and merchandise.
  • We think the challenge and the fun of a cross-cultural game jam with potentially unexplored game engines and a lesser-known programming language is the main reason to participate, but to celebrate this event, we also have prizes from Defold, Corona, DevGAMM, and other partners. We’ll update details about the prizes and awards shortly..
  • DevGAMM gathers 2000 indie developers in Minsk, Belarus to check out fresh local indie games and share the experience. It is a great opportunity to connect to the best teams from the Eastern European region and learn from global industry experts.
  • The #CoronaDefoldJam winners of the Community Choice, Best Corona Game, Best art with Corona, Best Defold Game, Best Technology with Defold are eligible to visit DevGAMM Minsk 2017 (November 16-17). 
  • If you think your jam-winning game is not ready for prime time at DevGAMM, you’ll be welcome to talk to the team and agree on showing your other game.

Welcome to #CoronaDefoldJam!

This jam is all about mostly unexplored 2D game engines, the Lua programming language, and maybe some Eastern European mood. has traditionally catered to a mainly Russian-speaking segment of the Internet, but we feel everyone wins with more diversity.

John Romero will make you love Lua

The rules for #CoronaDefoldJam


Lua is the language of choice, so pick up either the Defold or Corona engine.

  • Yes, only those two this time .
  • You are welcome to reuse some existing code/assets (asset stores, public packs like this and etc. are also fine), but the game has to be created especially for the #CoronaDefoldJam.


We know that mastering new tools takes time, so this jam is a whopping two months long.

  • Starts July 28, 2017 (or the 29th depending on your time zone).
  • Ends October 1, 2017.
  • “Best Community Game” will be announced on October 17th.


We'll have 2 main categories of winners at #CoronaDefoldJam:

  • Public voting by community here at with criteria: Gameplay, Graphics, and Overall.
  • Projects hand-picked by our friends from Corona, Defold, and DevGAMM.

Prizes or Small nice things to give away to the jammers

We’d love this “befriend everybody and love Lua” initiative to be memorable, so Corona, Defold, DevGAMM and potentially someone else have contributed some fantastic items to give away to the jammers. Here is what we have so far and are looking for more:

Friendship for the win!

We’re befriending the Russian and the international community, two somewhat rival game engines, and highlighting Lua as a programming language for game development. Our goal is to bring everyone together with an opportunity to showcase their greatness. This is a lofty goal which we’re attempting to reach, so please bear with us! We’re determined to do our best to run a great jam!

Getting started

We suspect you’re new to both Corona and Defold. Here are the pitches for both of them. Choose one and head to the getting started page.

The Defold ( is a 2D-focused game engine crafted at King for those who care about rapid iterations and the fastest possible runtime performance.
