xbox 360 G points

It's gamerscore. You earn it when you earn achievements. It's not used for anything but bragging rights.

Hi

As smwutches states these are two separate things.

G score, gamerscore is shown on xbox and reflects your achievements on xbox for unlocking things in game or apps, some view it as a badge of your skill as typically the better you are the more games you 100% complete getting higher score, others care less
about it, just solely for fun.

Then reward scores are for doing quizzes, buying stuff off xbox store and using bing etc and can be redeemed for items such as game passes, live codes or credit awards etc.

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.

Welcome to the site and Xbox. Really the Gamesocre is just for each player. Some play games to simply get every achievement they can from a game while others do not. Like the others have said, they really do you know good except track your progress on some
games.

Sorry but as I said,if you have a Gamerscore reset all your 360 achievements are reset,including the ones you unlocked legitimately,even if you only modded 1 achievement.

No one will give you your Gamerscore back.
