The Public Gambling Act of 1867, which applies to all of India, makes it a crime to either run a “public gaming house” or to even be present at one, and provides criminal penalties for both”. But it does not talk about online gaming.
Karnataka High Court in Indian Poker Association v. State of Karnataka, the Court ruled that playing skill games like poker in recreational club is permitted and no license is required for the same on 8th October 2013.
Under the Constitution, betting and gambling are State subjects under Entry 34 on List II of the Seventh Schedule
thus individual States do have the power to make their own legislation. To put it simply, the general laws of India concerning gambling apply unless a state specifically sanctions it.

Most state laws and the central statute exclude ‘games of skill’ from being categorised as acts of ‘gambling’. Yet a ‘game of skill’ had not been defined under these laws.

Till date no other game has explicitly received such a judicial nod. However, a Madras High Court judgment concluding that a ‘game of skill’, if organised for profit, would still amount to ‘gambling’.

The petitioners stated in their plea that they were playing rummy and bridge, which were neither wagering nor gambling under the Gambling Act.
Therefore, till the clouds of ambiguity remains regarding the "game of skill and gaming for profit" its better to stay away from these gaming sites who are organizing these games for profit.
