help for level clearance

The "Help a Friend" feature is a test feature in only some players' games. It is still being tested but seems to work in a way that it is impossible for anyone to ASK for help. King will give you a selected group of players in your friends list to "help pass a level" by playing it. If you pass their level they get some boosters which may or may not help them pass the level they are stuck on. There is no way for a player to ask for help, but if you are stuck for a long time, maybe King will ask another player for some help on your behalf. As the feature in not in many players' games and gives no reward to those helping out I wouldn't count on that.
