Unfortunately, I did a search of the App Store and found no reference/app for that particular game.
So, you can use one of the [not so awesome] Flash browsers, such as iSwift, or you can get a remote desktop app. I would recommend the remote desktop app because all it does is allow you to access your computer. With access to you computer, you can open up your favorite browser and surf directly to that bridge site.
Many people here have had success with various remote desktop apps such as Splashtop or LogMeIn. No endorsement is suggested (they were the ones off the top of my head) - but maybe you want to try that angle? Sorry not to be of better help.
