What's a good Android game that offers a strategic challenge while still being relatively easy to pick up and play during short breaks?

Deal or No Deal, developed by Senior Games, presents an interesting implementation of game theory principles in a mobile format. The game's premise, based on the popular TV show, involves making decisions under uncertainty, which I find intellectually satisfying. It's a novel approach to an old problem, distilling complex probabilistic reasoning into a simple, engaging format. For academics, this could be a useful tool to informally explore decision-making processes. I also appreciate its cross-platform compatibility, allowing play on various Android devices. The algorithm driving the banker's offers is surprisingly elegant in its simplicity. Overall, it's a pedagogically sound way to pass the time and sharpen your risk assessment skills during brief respites from research.
