Achievements, Experience Points (XP), and levels
With many Google Play Games, you can earn achievements and experience points (XP), and then track them all from the Play Games app .Achievements
When you're playing a game, you can earn achievements that mark your accomplishments. The more you play, the more chances you'll have to earn achievements.
Whether it's earning an achievement for a high score, completing new levels, or anything else, you can keep earning achievements as you make your way through a game.
When you earn an achievement, you'll see a pop-up overlay that shows what you've unlocked.
In-game achievements can also earn you experience points (XP) that correspond to the difficulty of the achievement. The more difficult the achievement, the more XP you will earn.
While playing a game, you'll see a notification when you've earned enough XP to level up your Play Games profile. You can view your XP, level, and individual achievements with the Play Games app.
