I need a coder for my arcade business

My project is a twist on the modern arcade. It allows players to compete head-to-head in a series of games they choose. On top of that players can wager an item from our shop, restaurant, or bar to up the ante. I need a way for my arcade games to be linked to one another so that the player's scores update as they complete each leg of the series. I need this to work across all of my games like, a baseball mini-game, air hockey, darts, the punch power game, etc.
