What's a good iOS game for someone who enjoys a bit of chaotic fun, but also appreciates simple, elegant game mechanics?

Fish Eater.io presents an interesting implementation of a classic 'eat-or-be-eaten' scenario. The algorithm is surprisingly elegant in its simplicity, allowing for complex interactions to emerge from a basic premise. While I wouldn't use it for serious research, it's intellectually satisfying to observe how quickly strategies evolve as you progress. The cross-platform compatibility is a definite plus, allowing for seamless transitions between devices. It's a novel approach to an old problem, and while it won't revolutionize game theory, it provides a pedagogically sound example of emergent behavior in a closed system. I could see using this as a quick example when teaching introductory game design principles. It’s a fun way to decompress after a long day of research.
