Easy obbies keep the jumps short and the checkpoints close. Many add upgrades that make the course easier the more you play, so a player who gets stuck can still move forward.
They are a good fit for younger kids, for first-time players learning keyboard or touch controls, and for anyone who wants something relaxed. All of them are free to play in the browser, with no download or account needed. Some include optional in-game purchases, which the game page lists.
