The mobile game "MonsterBash" had a huge success in the last months. MonsterBash is similar to Pokemon. You can be challenged by bluetooth and fight against other Monsters. The winnner steals points from the loser. Points can be changed into money. To give an incentive for downloading the program, every player receives free assets of $ 5.
Especially for teenagers this kind of incentive works. 80% of the players are younger than 20 years.
Arguments: Giving free access to the game and an incentive of $5 to start, this could help to overcome network effects which often prevent success of mobile applications.
Teenagers could be a possible target group, because they have a lot of time for playing games, and like to compete against each other.
What is the legal situation. Is it legal to implements such games that are about winning money?
What could be other incentives to overcome the network effects?
