Looking to play online slots just for fun, without risking any cash? Or maybe you simply want to try out unique slot machines you haven’t played before?
Sounds like you’re on the hunt for the best free online slots!
We’ve ranked and reviewed the top free slot sites on the internet. Our top picks host thousands of exclusive, high-RTP, and entertaining slot machines to explore.
Plus, if you do decide to play real money games, it’s easy to claim a generous bonus and up the stakes. Red Dog was our #1 pick overall, but we’ve got 9 honorable mentions that are worth checking out.
Let’s begin, shall we?
Red Dog allows its players to spin through 120+ free online slots with no strings attached!
Their interface is beginner-friendly, and it’s a dream to use on smartphone devices. Additionally, you can play through their entire betting library for real money if you decide to do so after trying out the games in demo mode.
Red Dog prioritizes quality over quantity with 120+ cutting-edge free slots reels from Realtime Gaming (RTG).
They’re always adding more games to their betting library, so you’ll find something new to explore every time you log in.
Surprisingly, their selection of free slots and real money video slots are one and the same. You’ll have the chance to enjoy hours of free entertainment and pinpoint your favorite machines. If you’re searching for recommendations, Gemtopia was by and large our top-rated slot game.
When you need a break from the best real money slots, you’ll have access to 12 live dealer games and 30+ virtual tables.
Free slots are cool, but if you want to up the stakes, use the bonus code “WAGGINGTAILS” with your first 5 deposits. You’ll redeem a 225% slots bonus up to 5 times, and high rollers can score up to $12,250 in casino credits!
Notably, NeoSurf and crypto depositors will claim an extra 20% bonus.
You’ll have 3 weeks to satisfy their playthrough and cash out a maximum of 30x your original deposit. If you plan to go big or go home, Red Dog puts serious money on the table.
If you like Red Dog Casino enough to play for real money, you can make deposits through fiat or cryptocurrencies.
They accept Bitcoin, Litecoin, Ethereum, Tether, Flexepin, NeoSurf, and credit card payments. If you prefer, you can also fund your account by phone.
You’ll have to deposit $10 through NeoSurf/Flexepin, $20 via crypto, or $30 by credit card before claiming Red Dog’s 225% slots package. However, you’ll have to withdraw $150 or more per transaction, which is a bummer for low-stakes players.
There’s no download required to spin through Red Dog’s free slots on mobile. Their instant-play app works through your smartphone’s web browser to put 120+ high-quality machines at your fingertips!
Every game in their library is fully optimized for smaller screens and older devices.
Lag is non-existent, and you’ll get to enjoy an identical gaming experience on desktop or mobile.
Red Dog’s dedicated support team is available 24/7. Players with questions and concerns can get in touch by phone, email, and live chat! It’s rare to find a phone line associated with modern gambling sites, but Red Dog breaks the mold to satisfy traditional players.
That said, live chat users will enjoy the fastest assistance. Our experts received a chat reply from a real agent within 30 seconds.

Ignition Casino is primarily known for the 24/7 poker room, but its collection of free-play machines and “Hot Drop Jackpots” is guaranteed to keep slot enthusiasts occupied.
Ignition doesn’t have that many free slots to choose from, but their current lineup includes 60+ fan favorites. Notably, you can also spin through their machines for real money!
On that note, big-fish hunters looking for big prizes will appreciate Ignition’s “Hot Drop” Jackpots.
Unlike regular progressives, Ignition’s four “Hot Drop” Jackpots dish out a maximum of $11,000 every single day.
If you manage to get even luckier on 777 Deluxe, A Night With Cleo, Golden Buffalo, or Reels of Fortune, players who win Ignition’s “Super Jackpot” can walk away with up to $250,000 in real money.
If you’re here to play slots for real money too, Ignition’s welcome bonus won’t disappoint.
They’ll double your first cash deposit up to $1,000, but crypto depositors will receive a 150% casino match worth up to $1,500. You can use every penny to play your favorite slot games!
Skill gamers will claim an identical crypto or fiat reload bonus to use at the poker table. Make your second deposit – Ignition provides cash players with a 100% reload poker match up to $1,000, and crypto players will claim another 150% poker match up to $1,500.
You’ll have to meet 25x wagering requirements across the board.
Players looking to move beyond free slots play can deposit real money through Bitcoin, Litecoin, Ethereum, Tether, Bitcoin Cash, a voucher payment, NeoSurf, or their credit card. Across the board, you’ll have to fund your account with $20 via crypto or $25 in cash to get started.
While all crypto payouts are 100% fee-free, cash bettors will have to deal with nominal processing surcharges. If you don’t want to wait for your earnings, we’d suggest playing your favorite real-money slots with Bitcoin!
Ignition has a downloadable poker app for iOS and Android devices, but you’ll have to spin through free slots using their mobile-friendly website. Luckily, Ignition mimics the functionality we’d expect from a native Apple or Android client.
Even when loading up 3 machines in different browser tabs, we didn’t encounter any noticeable lag. Games load in seconds, and graphics don’t take a pay cut on mobile devices.
Ignition doesn’t offer phone support, but new sign-ups can expect white-glove service through live chat and email.
Like Red Dog, Ignition’s team handles player inquiries on a 24/7 basis. We received a live chat response in seconds, and we got an email reply from a real agent within 6 hours.

Unfortunately, fiat gamblers are slammed with high processing fees and slower withdrawals. If you’d rather avoid a 7.5% credit card fee and receive 24-48 hour payouts, we’d suggest using cryptocurrency to play here.

All 195+ of their classic slot machines work flawlessly on your smartphone, and you can spin for gold while on the move with 36 lag-free progressive jackpots.

Crypto payouts are your best bet here – they’re processed within 1-2 working days, and they’re 100% free of charge!
Ducky Luck is a fairly new online casino, so it’s not surprising that their mobile website doesn’t respond well through older smartphones.
If you can deal with a tiny bit of lag and the occasional forced reload, it’s easy enough to power through on your iPhone 5S.
And if you have a phone created within the last 5 years, you won’t have any problems spinning through Ducky Luck’s slots while on the go.
Ducky Luck offers excellent customer support by live chat and email, but there’s no dedicated phone line for traditional players to call.
