Dear friends,

Welcome to another Retro Programmers Inside (RPI) Game Jam, which is also hosted by Phaze101 on

This time Retro Programmers Inside offers you a Game Jam that brings a famous modern web browser game to your retro machine.

As always the idea behind our Game Jams to increase knowledge and awareness around the retro computers that we all love. 

The challenge consists in creating an identical or original version of the most famous Google Web Browser game, that is Google Trex which you can find references here.

The challenge is just a way to have fun with our beloved retro computers, so let's bring Google Trex to your favourite retro machines. Most of us has played the game on your favourite Google Browser so why not build and play it on your favourite retro computer?

If you never participated in one of the Retro Programmers Inside (RPI) challenges, this is the Golden opportunity for you to start! The game, thanks to its simplicity, can also be programmed by beginners, on any 8/16 bit retro computer. 

As most of you know this Game Jam is just for the fun of it and for learning purposes. Your win is your achievement in completing such a challenge. 

  • You can use any programming language of your choice.
  • Solo Developers or teams are allowed.
  • You are allowed add variants, nice graphics, etc. etc.
  • No Consoles / DOS / Windows / Linux / Mac or any x86 machine

 In short, it really is a game for everyone.  Anyone who has difficulties, however, can always get in touch and we  are always happy to help.

At the end of the challenge there will be a live stream event in which all the games made will be shown.

 This is our way of celebrating the Game Jams and how everyone gets his glory.
