Help

It is not possible to send a request for help in the "Help a friend pass a level" feature. It is a new test feature in the game which some players have. You can only help others, not ask for help, and get no reward for doing so. Other may help you if you are stuck on a level. If they do some boosters will show up on your board and may or may not help you pass the level. But since only few players get this feature in their games it is not very likely you will receive help yourself as your friends may lack the feature.
