xbox achievements points rewards

Rewards points are not the same as gamerscore. The 37k you see on Xbox is your achievement score. The points on Rewards are gained by completing rewards tasks. The achievement score is just for show. It gets you nothing. Your rewards points are the only ones that can be used to acquire things.

If you're part of Microsoft Rewards, that program sometimes has an event where you can earn Microsoft Rewards Points by getting Achievements. It runs at least once a year for about a month. The event matches your Achievements up to 10,000; one Rewards Point for every Achievement Point. eg get 2,500 more Gamerscore that month and you get 2,500 Rewards Points.

That's pretty well the only time you can get Rewards Points from Achievements.

Hi what do you mean by Grandmaster Points? XBOX Achievements or Microsoft Reward Points?

The 2 sets of points are not the same thing. The points on the Rewards app are how many points you've earned through the Rewards program. The points on the Xbox dashboard is your gamerscore. Gamerscore is earned by earning achievements in games.

MS Rewards and XBox Achievements are not the same, no. Achievements is your gamer score tied to the achievements you unlock when playing. Rewards are the points you get from completing activities....some activities are related to achievements (for example, there's a Daily 50 points to be gained by unlocking an Xbox Achievement) but quite a few are related to online searching etc.

Also, you don't have to be a gamer to earn Rewards points.
