I want to introduce you to our multiplayer game framework.
We do support mobile and PC and is all online - so you don't need to make iPhone app, android app, etc..your players just need any kind of browser and that's it.
Please take a look at the documentation and examples HERE
We have build entire game portal using it, take a look at it here www.lan.bg
For instance - it took 1 man 7 days to build our "Ludo" game including the server, the client, the graphical design and the game logic+ AI
Depending on connections number you can use the framework for FREE (if you are building small game with less connections) or for bigger companies with lots of players (and connections) - you have to pay small monthly based tax.
The documentation is very very detailed , but if you have and questions, suggestions, offers, please do not hesitate to contact us at: firstname.lastname@example.org or by post here.
