Welcome to 3583 Bytes

3583 Bytes is an independent game studio based in Calgary, Alberta, creating games for players who want experiences that are fun, approachable, and built to last.

Founded in 2012 by Adam Berent, 3583 Bytes is best known for Train Sim, along with other long-running titles including Dinosaur Sim and 3 Jewels. Our focus has always been simple: make games people genuinely enjoy spending time with, then keep improving them over time.

We care about games that are easy to pick up, rewarding to come back to, and full of personality. Whether that means relaxing train gameplay, creative simulation, or accessible mobile design, we try to build experiences that feel welcoming without feeling shallow.

Best Known for Train Sim

Train Sim has become the studio’s flagship title and the clearest example of how we like to build games.

Over the years, Train Sim has grown through steady updates, new content, feature improvements, technical cleanup, and direct player feedback. It is designed to be approachable for new players, satisfying for longtime fans, and flexible enough to support both relaxed play and deeper experimentation.

That long-term support matters to us. We do not just want to launch games. We want to keep making them better.

How We Build

3583 Bytes is a small indie studio, and that shapes how we work.

A lot of game development is not just big feature announcements. It is iteration, maintenance, bug fixing, experimentation, and showing up consistently over time. We believe that kind of steady care makes a difference, especially for long-running games.

Our goal is to create games that players can trust will keep improving, with attention paid both to new ideas and to the details that make the experience smoother, clearer, and more enjoyable.

What does 3583 Bytes Mean?

3583 Bytes was the amount of free program memory that an 80s micro computer called the VIC-20 had available for writing  programs.  It is enough to hold about a single page of text.  Yet the VIC-20 had some really fun games & was a very successful micro computer of its time.  Its It is a reminder of both the speed with which technology changes, and how much can be accomplished with very little resources.
