I have a ndb model class:

class Game(ndb.Model):
    gameID = ndb.IntegerProperty()
    gameName = ndb.StringProperty()

Is there any way to quickly just delete all entities thats stored in the database for this class? Something like Game.deletAll()

Answer

No, but you could easily do this with something like:

from google.appengine.ext import ndb

ndb.delete_multi(
    Game.query().fetch(keys_only=True)
)
