With a Smartphone, mobile game players can play online multi player games even when they are moving. However, most operating systems on smart phones do not support multi-tasking. Therefore, games that take long time to think have trouble to contact a gamming server. This paper presents an online game platform for instant messaging on IMS. It can reuse existing instance messaging infra by using REST API server. The REST API server converts REST messages to SIP messages. The example REST and SIP messages are described. Also, the call flows from/to the REST API server is introduced. The developers of gamming system do not have to learn complex SIP messages.
