Browser Tick Based MMO Minigames Modifications

The game is a scifi style space strategy game where users develop there planets, research and develop new ships and wage war on other players. I'm looking for someone to modify a series of single player minigames to be intergrated with the MMO. There are 4 different type of minigames and they should be designed to fit in seamlessly with existing content. After completing a minigame a bonus should be applied to the account based on their success. The actual type of minigames and style implemented will need to be discussed after submitting the proposal. One of these minigames does need some additional work in order for it to be used but we can discuss this in chat prior to awarding. Please be aware game code is php/mysql based. The minigames are written in php/js/jquery/html5.
