What's the best Android game for quick, fun running sessions with collectible characters?

CookieRun is a mobile game that stands out for its blend of endless running and character collection, making it well-suited for quick play sessions. The core gameplay involves guiding various cookie characters through obstacle-filled courses, with each cookie boasting unique abilities and visually appealing designs. Features like the Trial mode offer varied challenges that keep the experience fresh, while the progression system allows players to collect and upgrade cookies over time. However, reviews indicate that the upgrade process can feel grindy, especially for legendary cookies, which may require significant in-game currency or patience. Users report that the initial layout might be confusing, but muscle memory develops with regular play. Despite some pay-to-win elements in the meta, the game remains enjoyable for casual players who appreciate its creative aesthetics and straightforward fun. It's a solid choice for commutes or brief breaks, where its bright visuals and responsive controls provide reliable entertainment.
