Best Endorphina Casinos 2026

Endorphina made a Bitcoin slot back in 2015.

It’s called Satoshi’s Secret, and it launched at a Bitcoin conference in Prague. That’s still how a lot of us first heard the name.

But the studio has moved well past one crypto slot. Most crypto lobbies now carry more than 200 Endorphina games, with a bonus you can buy and a whole series played with dice. And if you want to compare, the crypto slots worth your spins from every studio are rounded up in one place.

These are the Endorphina casinos I’d point you to, ranked.

Which Endorphina Casino Fits How You Play

Biggest Endorphina Library – Wild.io

Wild.io

Free bet
SPORTS
100% up to $200 free bet

More than 230 Endorphina games sit in Wild.io’s lobby, which is the largest library I found.

And Satoshi’s Secret has its own page there. That’s rarer than you’d think, because it was missing from every other lobby I checked.

Our exclusive here is 200% up to $1,000 plus 300 free spins. And when you win, you can withdraw up to $100,000 a week.

What’s the catch? The package carries 40x wagering and a $5 max bet. So I’d keep the bonus away from Bonus Pop until it’s cleared.

Most Endorphina Dice Games – Bitkingz

Bitkingz

No deposit Exclusive
BCK100
100 no deposit free spins

Bitkingz carries more Endorphina Dice games than any casino I checked, with over 30 of them in a library of 220+.

Most lobbies stop in the low twenties. So if the dice versions are why you’re here, this is the one I’d open first.

New accounts get 150% up to 5 BTC plus 150 free spins with code BCK.

However, both parts carry 45x wagering. That’s a fairly long road on a match that size.

Endorphina Bonus Buy Slots – Katsubet

Katsubet

No deposit Exclusive
30BET
30 no deposit free spins

Katsubet gives Endorphina its own bonus buy section, so you can see every game with a Bonus Pop option in one place.

More than 70 Endorphina games sit on it. You can also try them in demo mode before you put a coin in.

The welcome offer is 100% up to 1.5 BTC plus 100 free spins, with 35x wagering.

But the free spins have a $100 cap on what they can win. So I’d treat them as a look around, not a bankroll.

No Deposit Free Spins – 7Bit

7Bit

No deposit Exclusive
75BIT
75 no deposit free spins

7Bit’s 75 no deposit free spins only need a code, and the code is 75BIT.

That’s a cheap way to try the lobby. And the lobby has over 200 Endorphina games, including Dice versions.

Sadly, the spins carry 45x wagering and a $50 cashout cap. So I use them to learn the site, then pick my Endorphina games with my own crypto.

Bonus Pop, Book Slots, Dice, and the Risk Game

Most studios lean on one big mechanic. Endorphina has four you’ll keep bumping into, and each one changes how a session plays.

Bonus Pop

Bonus Pop is Endorphina’s name for a bonus buy. You pay a set price, and the game drops you straight into its bonus round.

The price depends on the game. On Janissaries, the priciest option runs close to 500x your bet. So a $0.50 stake turns into a $250 spin.

And it won’t make you more likely to win. You’re paying to skip the wait.

Here’s the part most people miss. Endorphina’s own game pages say Bonus Pop may not be available at every casino, depending on the jurisdiction.

So I check the lobby before I pick a casino. At three of the casinos above, 70 to 80 Endorphina games sit in the bonus buy section. If a casino shows none, the button probably isn’t there either.

Book Slots

A long run of Book games lives here, from Book of Santa to Book of Oil. They all share one idea: a symbol that expands during free spins.

But Book of Vlad does it differently. Blood drops fill a meter for each symbol, and a full meter makes that symbol expand and adds two more free spins.

So the bonus builds as it goes. It’s the Book game I keep coming back to.

The Dice Series

A Dice slot is an Endorphina game with dice faces in place of the usual symbols.

Everything else stays put. Chance Machine 5 and Chance Machine 5 Dice both run at 96.02% on five fixed lines, with the same wilds and scatters. Book of Vlad Dice matches its original at 96.04%, too.

So you’re choosing a look, not a different game. And that’s fine by me, because the dice versions read faster on a phone.

But how many you’ll find depends on the casino. Bitkingz carries more than 30, while BitStarz has close to 30 and 7Bit has a couple dozen.

And the list keeps growing. 3 Coin Towers Dice is one of the newest releases.

The Risk Game

Most Endorphina slots hand you a gamble after a win. Guess right, and you double it. Guess wrong, and it’s gone.

It’s a quick card game, and you can keep going on some slots. Solar Eclipse lets you double up to 10 times in a row.

Honestly, it’s the feature I trust myself with least. A decent win on a fruit game can vanish in two clicks.

So I set a rule before I start. I gamble small wins once, and I bank anything bigger.

The Endorphina Slots I Play Most

This catalog splits into two camps. Classic fruit slots have a gamble button, and newer grid slots are built for big swings. I play both, depending on my mood.

Satoshi’s Secret

satoshi's secret slot by endorphina cover art with a hooded figure behind a bitcoin symbol

This one has real crypto history. Six reels, 20 lines, and a hacker theme from 2015, when Bitcoin slots were barely a thing.

Its two bonus games are the fun part. One has you trading currencies, and the other has you cracking a bank account one level at a time.

But check the numbers first. Endorphina’s own game page now lists an 89.83% RTP, while most slot sites still quote 96%.

And the two do not match. So I open the help file before I spin, and I go by the figure the casino’s version shows.

Pros

  • A genuine piece of crypto slot history
  • Two different bonus games
  • Bonus Pop on the versions that carry it

Cons

  • RTP figures that don’t agree
  • Missing from a lot of crypto lobbies
  • The graphics show their age

Janissaries

janissaries slot by endorphina on mobile with the 6x5 grid and bonus pop button

This is Endorphina’s big-swing game. Symbols pay anywhere on a 6×5 grid, and wins tumble away to make room for more.

Then the multipliers land, from 2x up to 1,000x. In free spins, they stack up, which is when the balance really moves.

It tops out at 10,000x. But the base game can go quiet for a long time before that happens.

Pros

  • 10,000x ceiling
  • Multipliers that build through free spins
  • Tumbles keep a good spin going

Cons

  • High volatility
  • The bonus buy is expensive
  • Busy screen on a small phone

Starshine Crystals

starshine crystals slot by endorphina on mobile with the gem grid and bonus pop button

Starshine Crystals plays on the same 6×5 grid, but it’s a lot brighter. Star wilds smash objects on the reels and trigger more tumbles.

Four bonus symbols land you 15 free games, with a multiplier that keeps climbing. I’ve had rounds that did nothing and rounds that saved a whole session.

It also reaches 10,000x, and it runs at a 96.08% RTP.

Pros

  • 10,000x max win
  • Star wilds add extra tumbles
  • Bonus Pop where the casino allows it

Cons

  • High volatility
  • Long dry spells in the base game
  • Lots of flashing on screen

Burning Coins 20

burning coins 20 slot by endorphina on mobile with fruit reels and wilds

This is Endorphina’s hold and win game. Land six or more Burning Coins, and the reels turn into a respin grid.

Coins lock in place, collectors add them up, and multipliers go as high as 25x. Fill a column, and you hit a jackpot.

It’s medium volatility and pays up to 1,000x. So it’s the one I play when I don’t want to sit through a 10,000x game’s dry spells.

Pros

  • Easy to follow on mobile
  • Jackpots for filling columns
  • Medium volatility, so gentler swings

Cons

  • No Bonus Pop
  • 1,000x ceiling
  • Some casinos block it for bonus play

Book of Vlad

book of vlad slot by endorphina on mobile with the bonus pop book priced beside the reels

This is a vampire Book slot, 10 lines with seven free spins to start.

The blood meters make it. Every symbol has its own, and the more of them you fill, the longer the round runs.

It tops out at 5,000x, and it runs at 96.04%. There’s a Dice version too, if you’d rather play it with dice.

Pros

  • Free spins that can keep extending
  • 5,000x ceiling
  • Available as a Dice game

Cons

  • High volatility
  • Only seven spins to start
  • Short rounds when the meters don’t fill

Hell Hot 1000

hell hot 1000 slot by endorphina on mobile with four jackpot tiers above the reels

This is a classic fruit slot with 100 lines on a 5×4 grid. Stacked wilds do most of the work in the base game.

On top of that, there’s a pick’em game and a jackpot you collect over time.

It’s medium volatility at 96.02%, and it tops out at 1,000x.

Pros

  • Lots of small wins to keep you going
  • Pick’em game for variety
  • 96.02% RTP

Cons

  • 1,000x ceiling
  • Plain look next to the grid slots
  • No free spins round

New Endorphina Slots in 2026

3 coin towers dice slot by endorphina on mobile with dice symbols on the reels

Endorphina releases new games regularly. These are the newest in its lobby as of late September 2026:

  • Minotaur ReBurn, released 24 September, a 4,500x sequel with Bonus Pop
  • 3 Coin Towers Dice, a Dice take on a coin game
  • Lucky Stamps and Fortune Chests Dice
  • Hell Hot 1000 and Burning Coins 100

Endorphina RTP, Volatility, and Max Win

GameRTPMax win
Janissaries96.09%10,000x
Starshine Crystals96.08%10,000x
Book of Vlad96.04%5,000x
Minotaur ReBurn96.04%4,500x
Hell Hot 100096.02%1,000x
Burning Coins 2096.01%1,000x

Look at that RTP column first. Almost everything sits right on 96%, which is decent for any studio.

There’s one exception I left out of the table. Satoshi’s Secret shows 89.83% on its own game page, so it isn’t in the same league until you’ve checked your casino’s version.

So the real choice here is volatility. And that’s where this catalog splits hard.

Janissaries and Starshine Crystals can go flat for a hundred spins, then pay it all back in one round. Hell Hot 1000 and Burning Coins 20 pay smaller amounts, but they pay more often.

Before you pick a 10,000x game, read up on what a 10,000x ceiling does to a bankroll. Trust me, it’s easier to learn there than at the reels.

Bonus Rules That Trip Up Endorphina Players

These slots usually count toward wagering like any other slot. But three things catch people out.

  • Blocked games. At two of the casinos above, you can’t play more than 30 Endorphina games with bonus money. Burning Coins 20 is one of them
  • Bonus Pop. Casinos treat it as a bonus buy, and they usually block bonus buys until your wagering is done
  • The Risk Game. Some bonus terms don’t allow a gamble on bonus winnings, so read yours before you press it

So when I’ve got bonus money in play, I check the excluded list before I open anything. Then I leave the gamble button alone until the wagering clears.

And if you’d rather skip deposit terms entirely, no deposit casino bonuses for trying a new studio are the cheaper way in.

Is Endorphina Licensed and Fair?

Yes. Endorphina holds a Malta Gaming Authority license, plus approvals in Romania, Denmark, Sweden, Greece, and Peru.

It’s also growing in Canada. It went live in Ontario in April 2026 and got its Alberta license in August, which it says brings it to 59 regulated markets.

Gaming Laboratories International tests Endorphina’s games, and they run on a certified random number generator. That’s not provably fair, so you can’t check a single spin yourself. Either way, the house edge stays the same.

The casino is a separate question. A studio license covers the game, not the site holding your crypto. So I’d check each casino’s own license and terms before you deposit.

Studios to Try After Endorphina

If the coin games hooked you, Wazdan, whose Hold the Jackpot slots play like Burning Coins, is where I’d go next.

And if you like crypto history, BGaming and its crypto-first slot catalog are worth a look.

For everything else, every other slot studio I’ve covered sits on the provider hub.
