What is the Shark School slot?
Shark School is one of RealTime Gaming's ocean-themed releases, launched on March 27, 2014. The setting is a reef classroom full of cartoon sharks, which places it among the studio's lighter, character-led games rather than its gritty adventure titles.
Mechanically, the Shark School slot keeps to a familiar RTG template: five reels, three rows and 50 betways. What sets it apart from plainer RTG games is the stack of listed extras, with a bonus game, free spins, multipliers and expanding symbols all on the feature list.
It has no progressive jackpot. That matters more than it sounds, because several casino bonuses exclude jackpot slots, and a fixed-prize game like this one usually stays eligible. More RTG titles are in our full list of online slot reviews.
Shark School slot specs and RTP
Everything below comes from third-party catalog data, because RTG's own game pages couldn't be reached. Where a figure is missing, we say so rather than fill the gap.
The missing RTP is the biggest gap. RTG titles can be set up differently by each casino, so the help screen inside the game at your casino is the only reliable place to see the return it's running. If no figure appears there, treat the game's long-run cost as unknown.
How the Shark School features work
Catalog data lists six features but not their detailed rules. Trigger counts, the number of free spins and multiplier sizes aren't in our sources, so the paytable is where you confirm them. Here's what each listed feature does in general terms.
Wild: stands in for regular symbols to help complete wins. See our wild symbol entry.
Scatter: counts anywhere on the reels rather than on a line, and normally starts a feature. More in scatter symbols.
Free spins: a bonus round played at the stake that triggered it. This is part of the game, not a casino promotion with wagering attached.
Multiplier: increases a win by a set factor. Our data doesn't say when it applies or how large it gets; check the multiplier basics.
Expanding symbols: a symbol that grows to cover more positions on its reel, which can join up more wins at once.
Bonus game: a separate feature round. Its format isn't described in our sources.
Shark School volatility: what medium means for you
Medium volatility sits between frequent small wins and rare large ones. In practice, sessions on a medium-rated game tend to swing less sharply than on a high-volatility slot, but dry spells still happen and a short session can end with nothing.
Shark School's 15,000x ceiling is moderate for RTG. That's consistent with a medium rating: the game doesn't promise the extreme top prizes some high-volatility titles list, and the trade-off is usually a less brutal ride. Our slot volatility guide explains how ratings are set and why they're estimates.
Volatility doesn't change the house edge. It changes how the losses and wins are spread out over time, not what they average to.
A $50 Shark School budget at three stake levels
Your bet size decides how many spins $50 buys and what the 15,000x ceiling would be worth. The table uses simple arithmetic; it says nothing about how often anything pays.

Expected loss works out as total amount bet multiplied by the house edge. With no published RTP for this game, take this as a purely hypothetical example: if the edge were 4%, putting $50 through the reels would cost $2 on average, whether that's 200 spins at $0.25 or 10 spins at $5. The difference is variance. Ten spins is a coin toss; 200 spins gives the features more chances to show up.
For a medium-volatility game on a small budget, the lowest stake gives you the longest session. Our bankroll management guide covers stop limits. The house edge means losing over time is the likely outcome, so treat the $50 as the cost of entertainment.
Shark School vs other underwater RTG slots
RTG has returned to the sea many times. If you like the Shark School theme, these are the closest matches in our catalog data, with the figures as listed.
Megaquarium is the nearest relative, with the same 50-betway layout but a progressive jackpot added. Moby Dick is a smaller, older 20-line game, and Seahorse Surge brings cascading reels from RTG's newer catalog. If you'd rather avoid jackpot slots because of bonus rules, Shark School and Moby Dick are the two without one.
How to play Shark School for real money
Read what your state's law says about online casinos before opening any account.
Set a session budget and a time limit, and keep them separate from bills and savings.
Search the casino's lobby for Shark School; RTG casinos don't all carry every title.
Open the paytable to check the free spins trigger, multiplier rules and the RTP shown, if any.
Choose a total bet; the game spreads it across the 50 betways for you.
If a bonus is active, check the max bet rule before you raise your stake.
Stop when you hit your budget or time limit, whether you're up or down.

Using a bonus or free spins on Shark School
Because Shark School is a regular video slot with no progressive jackpot, it's the kind of game welcome bonuses are usually built for. SlotoCash's published welcome terms, for example, allow slots but exclude progressive jackpot slots, which would leave a fixed-prize game like this eligible. Always confirm in the terms at your casino.
Promotional free spins are a different matter: they're tied to named games, and none of the offers in our sources names Shark School. Any winnings from bonus play usually carry wagering requirements before you can withdraw. Read how free spins work before claiming.
Bonuses are slot-focused. Table games are often excluded or count for less, and breaking a max bet rule can void bonus winnings.
Is the Shark School slot legal to play in the USA?
That depends on your state, not on the game. Seven states license real-money online casinos: New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. RTG games like Shark School are mostly found at offshore casinos rather than at those state-licensed sites. Our page on states with legal online casinos has the detail.
The partners on this page are offshore and hold no US state license. Silver Oak publishes a license from Anjouan, held by Primrose Media Limited; SlotoCash and Decode don't show one on their sites, and third parties report different things. Michigan's Gaming Control Board named Silver Oak in its April 9, 2025 cease-and-desist release (opens in a new tab) and SlotoCash in its October 8, 2026 release (opens in a new tab), describing such sites as illegal offshore operators.
In practice, offshore play means no state regulator to complain to and no state protection for your balance. Read are offshore casinos safe before deciding.

Frequently asked questions
What is the RTP of the Shark School slot?
No RTP for Shark School is published in the sources available to us. RTG's own site couldn't be reached and the catalog data leaves the figure blank. RTG casinos can run different settings, so the help or info screen inside the game at your casino is the place to look. If you can't find a figure there, assume the cost per spin is unknown. Our guide to how slot RTP works explains why the number matters.
Is Shark School high or low volatility?
Shark School is rated medium volatility by third-party catalog data. That puts it between games that pay small amounts often and games that pay rarely but larger. Medium doesn't mean safe: a short session can still go without a feature. The rating is an estimate rather than an RTG figure. For more on what the label means for your budget, see what is volatility.
What is the max win on Shark School?
The listed maximum is 15,000x your total bet, from the attributes table of a third-party catalog. At a $1 spin, that would be $15,000. It's the theoretical ceiling and very rarely reached. Offshore casinos also apply withdrawal caps, such as SlotoCash's published $5,000 a week, so a large win can take weeks to cash out. Read about weekly withdrawal limits.
Does Shark School have a progressive jackpot?
No, catalog data doesn't list a progressive jackpot for Shark School. The top prize is a fixed multiple of your bet. That can work in your favor with bonuses, because some casinos exclude progressive jackpot slots from bonus play. If you want a sea-themed game with a jackpot, Megaquarium lists one. Our progressive jackpots explainer covers how those prizes are funded.
When was Shark School released?
Shark School came out on March 27, 2014, according to third-party catalog data. That makes it a mid-period RTG release, newer than the 2013 Moby Dick slot and older than Megaquarium from 2017. It still uses the classic 5x3 grid rather than the larger layouts of RTG's recent games. Browse other games from the studio on our RTG software page.
How many paylines does Shark School have?
Catalog data lists 50 betways for Shark School but doesn't say whether these are fixed paylines or ways to win. In RTG's older 5x3 games, the label usually refers to lines, though we can't confirm it here. Your total bet is spread across them automatically. The paytable at your casino will show the line pattern if there is one. Our paylines glossary entry explains the difference.
Can I play Shark School for free?
Some casinos offer a practice or demo mode for RTG slots, but whether Shark School is available that way depends on the casino. Demo play uses play credits, so nothing you win can be withdrawn. It's a sensible way to read the paytable and see the features before risking money. Our free slots vs real money guide compares the two.
Which casinos carry Shark School?
None of our sources confirms Shark School by name at a partner casino. SlotoCash, Decode and Silver Oak all list RTG or SpinLogic software, which makes it plausible, but the safest step is to search the lobby before depositing. An unofficial mirror site listed the game, but we don't treat those pages as reliable. For RTG-focused options, see our best RTG casinos list.
Is Shark School legal to play in Florida?
No, online casinos aren't legal in Florida, so there is no licensed way to play Shark School for real money there. Sports betting is legal only through the Seminole Tribe's Hard Rock Bet, and the Florida Gaming Control Commission sent cease-and-desist letters to offshore sites BetUS, Bovada and MyBookie on February 3, 2025, with the warning "Bettor beware." Players in Jacksonville, Miami and Tampa can report illegal operators to the commission. Our Florida online casinos page covers the law in more depth.
Can I play Shark School on my phone at Silver Oak?
Silver Oak's mobile casino page says its games run in the browser on iPhone, Android and tablets, with no dedicated app listed and a downloadable client for Windows PCs only. RTG titles such as Shark School use the same 5x3 layout on a phone, so the paytable and bet settings work the same way. Our sources don't confirm Shark School in Silver Oak's lobby, so search for it after you sign in. Our Silver Oak mobile guide explains browser play there.
How long do Silver Oak withdrawals take after a Shark School win?
Silver Oak's own terms allow 7-10 business days for review plus 7-10 business days for payment, so two to four weeks is realistic. Bitcoin withdrawals run from $50 to $2,500 per request, with fees of up to $40, and the weekly cap starts at $2,500, rising with VIP level. An 8% fee applies if a deposit wasn't wagered at least once. At that cap, a $15,000 win from Shark School's 15,000x ceiling at $1 would take six weeks. Our Silver Oak withdrawals page has every method and fee.
What is the minimum deposit to play Shark School at Decode?
LCB lists Decode's minimums at $5 by Lightning Bitcoin, $10 by Litecoin or Bitcoin Cash, and $25 for cards and other methods. Reported bonus codes such as DECODE111 also carry a $25 minimum, and codes change. At $0.25 a spin, a $25 deposit covers 100 spins of Shark School before any wins come back. These are third-party figures, so confirm them in the cashier. Our Decode banking review lists the methods reported for US players.
What should I do if a Shark School win isn't paid?
Start by checking whether the withdrawal is still in its pending period and whether the casino has asked for ID, proof of address or payment documents. Then contact support in writing and keep copies of every reply. Read the bonus terms too, since breaking a max bet rule or playing an excluded game can void winnings. Because offshore casinos have no US state regulator, your options beyond the casino are limited to the licensing body, if any, and third-party complaint services. Our guide on how to file a casino complaint sets out each step.
