Ideas for Simple Interactive Game Experiences in Mixed Reality

I’m exploring different ways to make interactive game experiences more engaging for users on mixed-reality platforms. I’m particularly interested in simple mechanics that are easy to understand but still encourage users to interact with the environment.

One idea is to use a spinning wheel game as a small interactive element—for example, as part of a rewards system, a mini-game, a learning activity, or a way to randomly select challenges.

For developers working with Unity, WebXR, or Meta’s interaction tools, what approaches would you recommend for implementing a simple interactive mechanic like this?

I’d also be interested in hearing about performance considerations, user interaction design, and ways to make these experiences feel natural in mixed reality.
