Fantasy punters

Hi there, I would like to create a fantasy betting app that is accessible to all. This app came to me as my brother loves to have a real bet on the football, rugby league, rugby and basketball. This is restricted to 18 and over of course because it is gambling and when he picks correctly (very seldom) there is a return that he is able to withdrawal. Well in this instance there will be no possible withdrawal as it's just for fun. I have come across many apps that mirror slot machines and casino games but never one where you have the option of picking sport outcomes and different options with the game selected by the user. I would like to model this off the real betting apps (BET365 and TAB alongside the Fantasy Premier League app). This would allow users to compete with friends and others around the world to see who has the luckiest luck or if they wanna call it skill go for It! Haha. They will be able to create leagues and join leagues with multi sport choices or just one specific sport. When the app is downloaded there will be a 250 coin gift pack that allows the user to get started. From there every week they will receive 50 coins to top up what they already have or to get them started again if there luck has run out. There will be an option to purchase more coins but the user knowing that they will never be able to withdraw real money from the app making it a no real return app hence FANTASY! We will need to fine 5 to 6 key and popular sports and generate offers and odds for users via collecting data from stats and previous results in regards to specific teams within specific sports. Users will be able to create Multis to increase winnings but making the possibility of the gamble harder to pick. Also they will be able to select single game options and options within the game itself while live in play. I hope to hear from you soon. Regards, Nick and his big punting brother Dan.
