Hi Nguyenan,
You can create dynamic room on AppWarpS2 in your zoneAdapter class that is overriding BaseZoneAdaptor class of AppWarpS2. You can use following functions to create Rooms based on your game requirements.
izone.createRoom(roomName,maxUsers,roomProperties);
izone.createTurnRoom(roomName,maxUsers,roomProperties,turnTime);
Let me know if more queries are concern.
Thanks & Regards
Vishnu Garg
