PlayMesh's Roshambo Online runs on a fairly simple platform. You start with the Lobby, where other Roshambo Online players talk to each other in a familiar PlayMesh forum. This PlayMesh forum is modeled after what you see in games like iMafia and iPirates, as well as the PlayMesh forums in the PlayMesh self titled iPhone application.
At the top of the PlayMesh forum Lobby area is a button that reads Play Roshambo Online. When you hit this, it will connect to the server and when a game is found, it will turn green and you can press it to enter a game.
There are two versions of PlayMesh's Roshambo Online: one that is free and one that charges $0.99. If you have the free version of PlayMesh's Roshambo Online then you will have an add first, and when you tap the touch screen you will be asked if you want to skip the ad or find out more. Once you skip the ad you will be taken to a match, and it will start at break neck pace.
You will have an icon for a rock, a piece of paper, and a pair of scissors. You select one of them within a short time period and then the two will be matched. This match awards on a best three out five and can be very competitive. This is all complete with animated graphics and display that keep things colorful and interesting.
Next to the Lobby button is one for your My Info page that lists your account info and statistics, including how many points you need to level up. Beyond these two main areas you also have settings in PlayMesh's Roshambo Online that you can use to turn off the sounds, which is nice. There is also a way to sign in to your PlayMesh account, providing that you are using the PlayMesh iPhone application.
