Players will receive a variety of achievements for the Grabs check-ins they put in. There are a lot of achievements. So are the conditions for receiving them.
Achievements are given out for a reason. Depending on their type or level, they also give you special "Achievement Points".
Different Achievements bring you different numbers of points. To view their terms and conditions, you will need to scroll down a bit under "My Achievements".
Here you can read descriptions of the achievements you already have, as well as the conditions for their obtainment.
In the Achievement History section, you can see how many Achievement Points each Achievement Point has brought you.
If a player has Grabs, the Achievement Points can be spent to farm $GRBS.
