What's a good iOS game for someone who enjoys observing emergent behavior in simple systems, almost like a digital evolution experiment?

As someone who appreciates innovative approaches to modeling complex systems, I found "Spider Evolution" to be a surprisingly elegant little time-waster. The core mechanic is quite simple – merging spiders to create new, more powerful variations. However, the emergent behavior as you progress is intellectually satisfying. It's almost like a simplified, interactive simulation of evolutionary principles. While it's not exactly rigorous scientific modeling, it provides a playful environment to observe how small changes can lead to significant outcomes. It's also cross-platform compatible, which is helpful for sharing findings with colleagues, and the simple mechanics mean it's easy to pick up and play. Though I am not sure how it would relate to academic research directly, it provides a fun and quick way to observe and think about evolution.
