Same Game on Multiple Devices

Yes, its possible ! But the procedures of having the same game running with the same stage of a game on multiple devices, are different but almost identical. e.g. - you can play war inc or Prime world Defenders II on two smartphones with the same stage of the game. on 1st case u have the option of recovery account at the very beginning but for the 2nd game u can get that option after completing stage 8 {synchrinize by logging into facebook ac with the user name provided in the player's profile in the game} So the idea is same for other games too.

Can these be achieve on blackberry?

It has to be an android OS; & windows phone can also do this.

OMG! Blackberry is getting dead day by day... Btw its my favourite phone brand, just a pity Android phones overtook it functionality and dynamic operation... I think BB is still existing cos of its durability and ruggedness
