Lightning strikes. That’s how people usually describe it when someone hits a massive payout. But if you’ve ever walked the floor at an Ameristar property—whether you’re in Black Hawk, Council Bluffs, or St. Charles—you know it feels different when the sirens actually start wailing. It’s loud. It’s chaotic. It’s the kind of moment that makes every other player in the room stop and stare.
Being an Ameristar casino slot machine jackpot winner isn't just about the money, though that’s obviously the main event. It’s about the sudden, jarring transition from "just another Tuesday" to "I need to call a tax attorney." Most people think these wins are myths or marketing stunts. They aren't. They happen more often than you’d think, but the way they play out behind the scenes is nothing like what you see in the movies.
What Really Happens When the Reels Align
You’re sitting there. Maybe you’re on your third coffee. Suddenly, the screen freezes. It doesn't spin anymore. The music changes from that repetitive chime to a high-pitched alert that cuts through the ambient noise of the casino floor.
First thing? Don't touch the machine. Seriously.
When a player hits a "hand-pay" jackpot—usually anything over $1,200 in the U.S.—the machine literally locks itself. It’s a security feature. You can't keep playing, and you can't cash out via the ticket-in-ticket-out system. You have to wait for an attendant. At Ameristar, this usually involves a slot floor person and a supervisor. They’ll need your ID and your Social Security number because the IRS wants its cut before you even leave the building.
The paperwork is tedious. It’s the least glamorous part of winning. You’re sitting there with a vibrating heart, and some guy in a vest is asking you to verify your home address for a W-2G form.
The Famous Hits at Ameristar Properties
Ameristar has a reputation for some of the biggest regional payouts in the Midwest and the Rockies. Take the Black Hawk location in Colorado, for instance. Because it’s a hub for high-stakes players, the jackpots there can be astronomical. We’ve seen winners walk away with $500,000 or more on progressive machines like Wheel of Fortune or Buffalo Grand.
It’s not just the high rollers, though.
Back in 2023, a lucky player at Ameristar Casino Resort Spa St. Charles hit a jackpot worth over $160,000 on a $5 bet. That’s the dream, right? The "penny slot" that pays out six figures. It’s rare, but these wide-area progressives (WAPs) are linked across multiple casinos, which is why the totals get so high. When you see a "Must Hit By" sign on a machine, pay attention. It’s not a guarantee you’ll win, but it tells you the math is getting tight.
The Math Behind the Magic
Let's get real for a second. The casino isn't "due" to pay out.
Every single spin is independent. I’ve talked to floor managers who see people sit at the same machine for eight hours because they think it’s "hot." That’s not how the RNG (Random Number Generator) works. The RNG is a computer chip that cycles through thousands of number combinations per second. When you hit the button, it just stops on whatever number is active at that millisecond.
- RTP (Return to Player): Most Ameristar slots hover around 90% to 95%.
- Volatility: High-volatility games pay out less often but offer those life-changing jackpots.
- The Progressive Link: These are the big ones. A portion of every bet from every player goes into a communal pot.
If you’re hunting for a jackpot, you’re basically playing a game of extreme variance. You have to be okay with losing your session budget for that 1-in-a-million shot at the top prize.
Does the Time of Day Matter?
I hear this all the time. "Go on a Tuesday morning," or "Wait until 2:00 AM on a Saturday."
Honestly? It doesn't matter to the machine. It does matter for your experience, though. Winning a jackpot at 3:00 PM on a Wednesday is a relatively quiet affair. Winning at midnight on a Saturday means you’ll have fifty strangers cheering (and maybe asking for a tip). Ameristar properties are known for their atmosphere, so if you want the "celebrity" treatment, go when it’s busy. If you want to get your check and disappear, go during the off-hours.
The Tax Reality Nobody Mentions
Being an Ameristar casino slot machine jackpot winner means you’re now a person of interest to the government.
In the United States, gambling winnings are fully taxable. If you win $10,000, the casino might offer to withhold the federal taxes for you (usually around 24%). I always suggest people let them take it right then and there. If you take the full amount in cash or a check, you’re going to owe that money come April.
State taxes vary too. Missouri and Iowa have different rules than Colorado or Mississippi. Some states allow you to deduct your losses against your winnings, but you need to keep a meticulous diary of your play. Most casual players don’t do this, and they end up paying way more in taxes than they should.
Strategies That Actually Work (And Some That Don't)
You can't "beat" a slot machine. You can, however, manage your play so you’re in a better position when a hit happens.
First, always use your PENN Play card (formerly Marquee Rewards). While the card doesn't affect whether the machine hits a jackpot, it tracks your "theoretical loss." This leads to comps—free hotel stays at the Ameristar resorts, dining credits, and even "Free Play" offers. If you’re going to be a winner, you might as well get a free steak dinner out of the deal.
Second, check the "Max Bet" requirements. On many progressive machines, you cannot win the top jackpot unless you are betting the maximum amount. There is nothing more heartbreaking than seeing the jackpot symbols line up and realizing you only won a flat $500 instead of $50,000 because you were betting the minimum.
Myths to Ignore:
- The "Warm" Seat: The temperature of the machine or the chair has zero impact on the RNG.
- The Lever vs. The Button: They do exactly the same thing.
- The "Just Paid" Curse: Just because someone hit a jackpot five minutes ago doesn't mean the machine won't hit again on the next spin. The odds are exactly the same every time.
Life After the Big Win
What do you do with the money?
I’ve seen people blow a $50,000 jackpot in the same casino over the next three months. It’s called "giving it back." The adrenaline of a big win makes you feel invincible. It makes you think you’ve "solved" the game. You haven't. You got lucky.
The smartest winners are the ones who take the check, walk out the door, and don't come back for at least a month. They pay off a credit card, fix the roof, or put it into a high-yield savings account. Ameristar will usually offer you a choice between a hand-pay in cash or a check. For anything over $5,000, take the check. Walking through a parking garage with $20,000 in your pocket is a bad idea, no matter how good the security is.
Essential Steps for Future Winners
If you find yourself staring at a screen that says "Call Attendant," follow these steps immediately.

- Stay at the machine. Do not walk away to find an employee. Use the "Service" button or wait for them to notice the tower light (the candle) flashing on top of your machine.
- Have your ID ready. You need a valid, government-issued photo ID.
- Think about your privacy. In some jurisdictions, the casino might ask to take your photo for social media. You can usually say no. If you want to keep your win private, tell the host immediately.
- Log your session. Open a note on your phone and record the date, the machine number, and how much you put in versus what you won. This is your "gambling log" for tax purposes.
- Tip your attendant. It’s not mandatory, but it’s standard casino etiquette. A small percentage of the win (if it's a few thousand dollars) or a flat $20–$100 for a larger hit is common.
The reality of the Ameristar experience is that it's designed for entertainment. The jackpot is the outlier, the "black swan" event. When it happens, it’s a blur of paperwork, flashing lights, and a very sudden realization that your bank account looks different than it did ten minutes ago. Play smart, understand the RNG, and always keep your ID handy. You never know when the millisecond you hit the button will be the one that changes everything.
Actionable Insights for Your Next Trip:
- Check the Jackpot Reset Amount: If a progressive jackpot has just been won, it resets to a "seed" amount. Wait for it to build back up before chasing the big one.
- Set a Hard Loss Limit: Decide exactly how much you are willing to lose before you walk in. Once it's gone, leave.
- Verify Your Rewards Tier: Higher tiers in the PENN Play system often get faster service for hand-pays, which gets you back to your night (or home) quicker.
- Consult a Tax Pro: If you win over $10,000, talk to a CPA before you spend a dime. They can help you navigate the "Session Accounting" method which could save you thousands in taxes.
