You might enjoy a stadium management style game where the goal is to develop the arena and unlock new improvements over time. It’s not too complicated, which makes it good for short sessions during the day. I first came across the app page https://play.google.com/store/apps/details?id=com.goodybamgo.stadiuminc&hl=pt while searching for similar games. After trying it, I found the progression system pretty smooth, especially if you like incremental upgrades and casual gameplay.
