Cashout Games

We need to build an android app that contains 5 different flash skill-games, such as Tetris, Snake, etc. We would like to find free or cheap versions of these games to use so you dont have to make them from scratch. We will need a token system built so that players can only play the game if they have a token. We need to accumulate the high scores of the games and display the top ten players on the app. We need to have the ability to reset the high scores daily, weekly, etc. We also need a progressive jackpot on the top of the app. The player with the high score of the day, week, etc. will win the progressive jackpot amount which we will send to them via paypal. We need the progressive jackpot to go up based on a percentage of total sales we receive from token purchases. After someone wins the jackpot, it needs to reset. We need separate jackpots for each game and separate high score tables. They need to be able to set up accounts and purchase with paypal, credit card, etc. We can go into more detail with the winning bidder.
