Which game engines use the least resources for casino games?

I can recommend light casino game engines such as Unity (lightweight configuration), Phaser.js, or other HTML5-based ones, with a high degree of flexibility for web development, cross-platform support between mobile and desktop devices, low requirements for hardware specifications, and great for developing in-browser casinos or applications. If you are looking for no-code/low-code tools, then I would suggest trying Construct 3, which allows for one-click deployment and works fine for slots or basic card games.

game engines if your desire is simply “lowest resources” - then pure JavaScript or WebGL frameworks may be superior to game engines – but you’ll write a lot more code. HTML5 solutions are also better if your goal is the smoothest web experience with the least download footprint. I’ve used them successfully for casual casino games that perform equally well on last generation tablets.

If you want more detail on any of the above, just let me know. I’ve been part of several start-up slot games companies in the past.

Unity is a great option if you’re looking for something with fewer system requirements. Unity is lightweight enough, but the champion in this department would be HTML5 + JavaScript. A free, open-source engine like Godot with its low resource usage is also an excellent choice for mobile. Most web casinos rely on these solutions to ensure fast load times. Drop me a line if you want more info and examples of how these frameworks have worked for other websites – I’ll happily share!
