What is a progressive jackpot?
A progressive jackpot grows with every bet placed on the games linked to it, then resets to a starting amount after a win. A fixed jackpot stays the same size. The help screen says which kind a game has and what you must bet to qualify.
What are the biggest US online slot jackpots?
The biggest reported US online slot jackpot is $9.28 million. These are reported wins at licensed US online casinos:
| Amount | Where | When | Details |
|---|---|---|---|
| $9.28 million | DraftKings Casino, Michigan | February 26, 2025 | Irish Pot Luck, from a 20-cent spin |
| $6.4 million | BetMGM, New Jersey | August 2024 | The previous US online record |
Reported by the Lawrence Journal-World in March 2025. Records change, and operators publicise only some wins.
Can a jackpot make a game worth playing?
Sometimes, in theory. Wizard of Odds lists progressive games with a known break-even point, where the jackpot becomes large enough for the RTP to pass 100%. Below that point the game costs you money on average. For most slots, the break-even point is not published, so you cannot tell.
What should you check before playing a jackpot slot?
Check the help screen for:
- Whether you must bet the maximum or buy a feature to qualify for the top prize.
- The RTP, and whether it includes the jackpot contribution.
- Whether the jackpot is linked across casinos or states.
What are the rules in your state?
Each state sets its own online casino rules. Pick a state to see its status, its regulator and the date we last checked it.
