Yeah for reward have many event and challenges... but the thing is that u need to pay 10k for play and when u win in return u get only few coins but if cant make u lose 10k... that is not good part of game.. u need to give same prize money for clear the level as we spend to play level... daimonds also not east to get even in higher bet.. too play need lots of coins but in reward u give very less coin which make game very boring...
