What’s the Deal With Online Slots?

Warning: Long post incoming. After a lot of internal back-and-forth, I am not endorsing these slots in mid-2026 for advantage play. Now, if it later became clear these could be exploited, I would not be surprised. But I’ve seen enough inconsistency to back off advocating for these as AP.

What games am I even talking about? Cash Falls, Ultimate Fire Link Cash Falls, and Cash Falls Add ‘Em Up.

If you were to play them, what’s the risk scale?

Risk Scale: Green (rarely more than 10 or so spins, but there are many different bets per game, there are many games per app, and there are many different apps)

If you were to play them, what should you look for?

Minimum Play: You’re mostly looking for blank starting boards or two or fewer locked symbols. Sometimes there can be three or fewer, depending on where they are. That’s incorporating the full board. Then you can also chase individual columns one spot away from complete and adding up to at least six times the bet. If the game offers a Fire Link feature, the column can be two or fewer spots away from completion, regardless of what the column adds up to.

Other: Were they a thing? Are they still a thing? Read on.

This is a tough one for me to endorse—and to be extra clear, I am not endorsing these games—as the jury is still out on whether these are beatable. I am only including this as a free Blog post because I find the whole thing interesting. If you’d like to skip this entirely, by all means.

But first, how could online slots ever be beatable? After all, there is no one who plays these games before you, so it’s not like you could capitalize on someone else’s progress (i.e., how any other advantage slot works).

But online slots have been exploited before.

Eric Raskin, who recently interviewed me on his Low Rollers podcast, wrote about how one such popular game, Ocean Magic, was exploited online for hundreds of thousands of dollars and quite likely much more. This article from 2019 states:

I realized that not only did the game start in an advantageous position on the $1 denom, $2 denom, and $3 denom level, but each time that you switched denoms, the board went back to the original state for one spin on that denom. So if you had played the $1 denom already, it didn’t go back to that state. But when you played the $2 denom for the first time, it started in that same state. And next the $3 denom, $5, so on and so forth. … 

He [math friend] got back to me and said that basically, for one spin, I was playing with a 126% edge. And then on three further spins, I was playing with a 40% edge. Which, if it was only a $3 bet, would not interest me. But when you’re talking about a $3,000 bet, that’s quite substantial.

The article noted: “[He] determined that one person playing Ocean Magic all the way up the denominations once in that advantageous state — and you could only do it once per account per casino — was worth, on average, about $80,000-$100,000 across all the online casinos in Jersey offering the game.”

The exploit? Players started with a bubble right down the middle on each bet. That meant a few spins with an advantage, followed by the typical edge for the casino after that. But if you created an account on each of these apps, including those from Borgata/PlayMGM, Caesars, and Hard Rock, you could play when you had an advantage and then move on after that was no longer the case.

But that was years ago. Surely, online casinos would have learned from such a catastrophic mistake, right? Maybe. Maybe not.

In 2025, some of my good friends who happen to be professional slot hustlers told me of this new exploit involving Cash Falls and Ultimate Fire Link Cash Falls. On each bet, often ranging from 20¢ per spin to $400 and possibly even more on some sites, you start with a blank board. 

Below is what it looks like on Ultimate Fire Link Cash Falls Olvera Street on the FanDuel app:

It’s not the exact starting board, as I forgot to take a pic of that, but the relevant point is there are no locked fireballs.

The goal? To hit a free games bonus, which you can see above on a $2.40 bet. When you have a blank screen, as was the case in this example, you have much more room than you normally would to land bonus symbols. And even if you don’t hit a bonus, because of all that extra real estate (reel estate ha ha), you could back into some small-, medium, and big-paying line hits.

Here’s one such example of that on a $3 bet on Ultimate Fire Link Cash Falls China Street on the DraftKings app:

On this spin, I landed four fireballs, which was not ideal. But because I had so much space, I also connected a bunch of fortune cookies, which paid $81 on that $3 bet. So, are you just looking for fully or mostly blank boards and nothing else?

Nope. Something like this example would be great:

After a few spins on my previously blank board, I built it up to what you see here.

At this point, I’d be very unlikely to trigger a free game bonus or have any sort of line hit because those fireballs are blocking a good percentage of the space. But you can see I have three Fire Link features active—those small coins below each reel indicate how long a column will be active; one, two, or three spins. And though the values of the other fireballs are small, with columns close to completion not featuring any above 1.5x the bet, having three active Fire Link features makes this a definite +EV play. (Even in mid-2026, I’d say that.)

I mentioned above in the minimum play requirements that I’m looking for a few different scenarios. I would suggest you read my separate entries on Cash Falls and Ultimate Fire Link Cash Falls so you get a sense of what to look for when it’s not a blank or mostly blank board, though I’ll describe it a bit below as well.

I opted to keep my minimum plays as simple as possible and combine all these games (Cash Falls, Ultimate Fire Link Cash Falls, Cash Falls Add ‘Em Up) into one. And you’ll notice above that I wrote: “individual columns one spot away from complete and adding up to at least six times the bet.”

Does this fit the bill?

This version of Cash Falls is called Willy Wonka Cash Falls Add ‘Em Up.

Here, I’m betting 60¢ per spin, and you can see that column one—which happens to be one of the easier columns to land, but we’re not going to dive deep into that in this simplified breakdown—has the following values: $1.20, 30¢, 60¢. The column will be locked and in play for us for three spins, indicated by those three small coins below that column. That’s $2.10 in value, which is 3.5x our bet and not good enough to play.

How about here?

This game cannot be beaten—again, maybe none of them can anyway—so this is a trick question. Make sure you’re typing in “Cash Falls” in the search bar for whatever app you’re on once you get to the casino (if you want to gamble at all):

That way you’ll get to all the games without wasting your time sifting through what felt like hundreds of other casino games. Also, make sure not to play games such as Regal Riches or Rich Little Piggies or Scarab or all the other advantage games you’d find in a casino. For all of them, you’re given the same starting board with no advantage element. And of course, you can’t be the one to “pay” until something becomes advantageous.

So something like this, sad to say, is unplayable:

Let’s get back to a few more examples of close plays or non-plays (I need to reiterate that I am not endorsing these games as AP; I’m just showing what to look for should you decide to play):

Here, on Cash Falls Add ‘Em Up Chariots of Rome, the column of interest is that second reel. We’re betting $2.40 per spin, and the values add up to $12, giving us 5x our bet in value. Yes, plenty of folks would play something like this, and they might be correct in doing so in a vacuum, but I’d rather be overly conservative for this sort of online game, where there’s still plenty of uncertainty to begin with. So because it’s not 6x the bet or greater, I’d pass. 

Here’s another example:

Here, you can see there are three locked fireballs in reels two, three, and four. Line hits will be slightly impacted, but this is still something I’d spin if I were to play the game in the first place. Some folks would only play with two or fewer locked, and even then, they wouldn’t want something like this:

Yes, it’s only two locked fireballs, but they happen to be in the first column. Why is that bad? Well, because line hits must build left to right, you’re unlikely to register any kind of winning spin involving matching symbols. Yes, you still have a huge board free to land bonus symbols, and for that reason some folks would spin on a setup like this, but I’d fall in the “line hits are too impacted” camp.

If you can’t already tell, there’s certainly some close calls and room for argument with these types of boards.

Let’s check another interesting example:

What is going on here with this Cash Falls Add ‘Em Up Gold board? It seems like maybe there are some locked coins, but they appear faded. Is this worth playing?

It is. That second reel was awarded the previous spin, so no coins are going to stick, giving us a fully empty board. Of course, you could still easily lose on this sort of play, but you can think of it as the same board as the reset one you’ll start each bet with.

My buddy sent me a fun example with a locked mega ($150,000).

In this oddball case, it was a $15 bet with a locked mega in column five (lost the pic; forgive me). There also happened to be only three locked fireballs in pretty neutral spots, so you could have made a strong case for playing it as is. But pretend there were more fireballs on the screen, compromising potential bonuses and line hits. Here, you have a very, very low chance of completing column five, as there’s just one locked fireball, and you need to fill in seven more spots.

It’s a $15 bet, so it could be possible to lose 10 or so bets. Let’s say you get a real tease and you lose 15x the bet. That’s $225—not nothing, but a drop in the bucket when you could land a $150,000 ball every blue moon.

I bring this up not to get you looking for megas, as those are exceedingly rare to ever see, but rather to keep your eyes open for one-off cases that may go against my fairly rigid minimum play requirements. If you play these games enough, you will see some interesting scenarios every now and then.

Something like this:

It’s kind of a “combo play,” as columns one and two are one fireball away from completion but are both quite low in value, while column five is three fireballs away but has a Fire Link ball. It doesn’t technically meet my minimum play criteria, but I’d still play something like this.

If you’re lucky, you’ll hit a bonus or two on some sizable bets and then have the bonus pay well when you do so:

Something like that is a bit above average from what I’ve seen so far, but it’s certainly not that uncommon (50x the bet or so).

Of note, many apps, including DraftKings and FanDuel, used to offer large bets (over $50) for games under the Cash Falls and Ultimate Fire Link Cash Falls umbrellas. Then they removed those, capping the bets at $10 for those games. Would they really eliminate big bets on the Cash Falls and Ultimate Fire Link Cash Falls versions and then add new games with huge bets if they could get exploited? 

You’d think if they were aware enough to remove big bets, they would not reopen the exposure on a different game. Heck, I’d think if they were getting exposed at all, they’d tweak the game mechanics to adjust for that exploit.

All of this to say, I’d be leery about playing these at all. It’s possible they patched it up for bigger bets or mitigated the advantage altogether. And it’s a big reason why I can’t give it the Slot Slayers stamp of approval. If you still want to play, check every app you’d like, as these are common games. You won’t just find them on FanDuel and DraftKings.

Also, if you’re wondering, to my knowledge this will not work in a real casino setting. Yes, you can still play all the Cash Falls variants the old-fashioned way (looking for favorable boards one or two places away from completion), but you can’t beat the games by looking for blank starting boards?

Why? Well, the RTP for an online casino can get set high (95% or more at times) because they don’t have the expenses a brick-and-mortar casino does. Because of that, I would not play blank starting boards in a regular casino, though I know of a few pros who still do.
