Some users have reported that when they attempt to spin the roulette wheel, the ball will on occasion, spin forever. There are a few reasons as to why this could be happening... Basically, the physics requires frame by frame calculations and some computers (mainly lower end computers with low memory) can struggle to process these real-time physics, so these calculations are not being resolved in a reasonable time-frame, and end up causing the ball to spin forever. I am aware of this issue, and currently looking for a possible way around it. I do want to remind users to read the system requirements, as I have updated them to better reflect what type of hardware should be able to run Roulette Simulator's physics calculations without issues. Part of the reason Roulette Simulator is entirely unique is because we don't use a random number generating system, and rather use physics entirely to generate a roulette outcome. This physics issue is happening to an extremely small amount of people, less than one percent, so it is extremely unlikely that you will face any issues if your computer hardware is relatively up-to-date. If you have any questions, feel free to post in the discussions community hub and I will get back as soon as possible. Thank you!
