The "permitted by default" category covers the largest group of states — Maharashtra, Karnataka, Tamil Nadu (post-2021), Delhi, Uttar Pradesh, West Bengal, Gujarat, Rajasthan, Madhya Pradesh, Bihar, Haryana, Punjab, Jharkhand, Chhattisgarh, Uttarakhand, Himachal Pradesh and most of the North East. In these states, the skill-game exemption is the controlling authority and no specific state restriction applies.
The "specifically permitted" category covers states where a state-level notification has explicitly addressed online skill games and confirmed they are permitted. Nagaland, Sikkim and Meghalaya fall into this category; the state gaming acts in these states explicitly exempt skill games from the gambling definition.
The "restricted" category currently covers Assam, where the state gaming act has been read to include online skill games within the gambling prohibition. Players in Assam should not play paid online rummy regardless of what the platform advertises.
The "contested" category covers states where the position is currently subject to pending litigation. Telangana and Andhra Pradesh have had fluctuating positions; both states have active petitions that may change the position. Players in these states should treat the position as unsettled.
The "no specific position" category covers states where neither the state gaming act nor any published notification addresses online skill games. In these states, the federal default applies (skill game exemption, permitted). The list includes most of the smaller states and union territories.
