Floor rules
What each class puts on the desk
Know before you sit
- Class I
- Traditional Indian gaming and social gaming for minimum prizes. NIGC history places regulatory authority with tribal governments. The jurisdiction paragraph does not list an NIGC or state share for Class I.
- Class II
- Bingo, including electronic aids, plus pull-tabs and similar games in the same location, and non-banked card games. Slots and electronic facsimiles are excluded. The tribe regulates Class II if the state permits that gaming and the NIGC Chair approves the ordinance.
- Class III
- Everything else, including slots, blackjack, craps, and roulette. The form must be allowed in the state, a compact approved by the Secretary of the Interior or regulatory procedures the Secretary approved, and an ordinance the NIGC Chair approved.
- Shared Class III
- Tribe and state share Class III internal controls, compacted games, and patron disputes from those compacted games. NIGC’s Class III share is the limited one named on the jurisdiction page — not a full takeover.
- Compacts and plans
- The tribe, Interior’s Office of Indian Gaming, and NIGC have jurisdiction over specific tribal-state compact matters and revenue allocation plans (per capita payments). This page does not restate any compact.
- Prize claims
- Start with the casino’s procedure, then the tribal gaming commission. NIGC usually refers the dispute to that regulator and does not interrupt the tribe’s process. It looks when there is no process, or evidence of fraud.

Primary desk
The tribe’s gaming commission regulates Class I, II, and III. Ordinance rules and prize claims start there.
Federal share
Monitors facilities, assists tribal regulators, and shares all Class II matters plus a limited Class III role.
Compact partner
Shares Class III internal controls, compacted games, and patron disputes from those games — not every class.
Criminal matters
The United States Attorney has jurisdiction over criminal matters involving tribal gaming. No further criminal map here.

Sequence
How to place one floor on the right desk
Step 01
Name the tribe first
The primary regulator is the tribal government and its gaming commission for Class I, II, and III.
Step 02
Sort the game by class
Class I stays with the tribe. Class II adds a full NIGC share. Class III adds a limited NIGC share and a state share on compacted games.
Step 03
Check the Class III gates
The game must be permitted in the state, a compact approved by the Secretary of the Interior or regulatory procedures the Secretary approved must exist, and the NIGC Chair must have approved the ordinance.
Step 04
Use the tribe’s dispute path
Get the prize-claim procedure from the casino or the tribal regulator and file there. NIGC does not step into an open tribal process.
Step 05
Keep commercial floors separate
A state-licensed casino, including an NGCB Las Vegas floor, is regulated by state authorities only.
Watch outs
Mix-ups that scramble the stack
01NIGC runs the casino
Tribes are primary. NIGC monitors, trains, and shares defined matters. It does not replace the tribal gaming commission.
02The state licenses every class
The named state share is Class III controls, compacted games, and patron disputes from those games. For Class II, the state piece is whether that gaming is permitted at all.
03A Vegas licence is tribal
NGCB-licensed floors in the list below are the state-only lane. Non-tribal gaming is only regulated by state authorities.
04Skip the tribe and write NIGC
NIGC says it will usually refer a patron dispute to the tribal regulator and will not interrupt that process.
05One criminal map for every case
The only criminal line used here is the NIGC sentence: the United States Attorney has jurisdiction over criminal matters involving tribal gaming.

Questions before and after you play
A 90-second guide cannot cover every table moment. Tap a group, then a question — answers are short paragraphs, not one-liners.
01Who sits where
Who regulates tribal casinos in the United States?
The tribe is the primary regulator of Class I, II, and III gaming. The National Indian Gaming Commission shares jurisdiction over all Class II matters and limited Class III matters. The tribe and the state share Class III internal controls, compacted games, and patron disputes arising from compacted games. Commercial casinos sit outside that stack: non-tribal gaming is only regulated by state authorities.
Is the NIGC the same kind of board as a state casino commission?
No. Tribes remain the primary regulators of their gaming operations. NIGC monitors facilities, provides technical assistance, and can use civil compliance tools under IGRA, its regulations, and approved tribal ordinances. That federal share does not turn NIGC into the day-to-day licensing board for every class.
Why is the tribe primary if a state compact exists?
NIGC history says the Supreme Court in California v. Cabazon Band of Mission Indians (1987) confirmed tribal authority to establish and regulate gaming independent of state regulation when the state permits some form of gaming. IGRA then preserved tribal regulatory authority over Class II and gave states a voice on Class III through compacts. The jurisdiction page still names the tribe as primary for all three classes.
02Classes and disputes
What are Class I, Class II, and Class III?
Class I is traditional Indian gaming and social gaming for minimum prizes, regulated by the tribe. Class II is bingo (electronic aids allowed) and, in the same location, pull-tabs and similar games, plus non-banked card games; slots are excluded. Class III is every other game, including slots, blackjack, craps, and roulette. Class III needs state permission for that game, a compact approved by the Secretary of the Interior or regulatory procedures the Secretary approved, and an ordinance the NIGC Chair approved.
Who handles a prize dispute at a tribal casino?
Ask the casino for its prize-claim procedure and follow it, then the tribe’s gaming commission if management does not resolve it. NIGC says that if you report the event, it will in most cases refer the matter to the tribal regulator, and it will not interrupt the tribe’s process. NIGC looks at matters where the patron was denied a chance to file, including no process or evidence of fraud.
Who has criminal jurisdiction over tribal gaming?
The NIGC jurisdiction paragraph states that the United States Attorney has jurisdiction over criminal matters involving tribal gaming. This guide does not add agencies, charging theories, or a state-by-state criminal split beyond that sentence.
03What this page is not
Are the Las Vegas casinos below tribal casinos?
No. They are commercial floors licensed through the Nevada Gaming Control Board, shown so you can see the state-only lane next to the tribal stack. NIGC history says non-tribal gaming is only regulated by state authorities. A listing here is not a tribal compact and not a tribal gaming commission.
Does an online state commission regulate tribal casinos?
No. Online rules such as New Jersey Division of Gaming Enforcement internet-gaming chapters describe a remote state stack. They are not the tribal regulator line on this page. For that remote stack as mechanics, read How online casinos work. For the land-licence map in plain language, read Is casino gambling legal in the US?
