The approvals in Denmark, Sweden, Ontario and Alberta mean Endorphina games have passed regulated-market certification, which requires published RTPs and lab-tested RNGs. Our MGA licence explainer covers what the Maltese B2B licence requires from suppliers.
Game design and features
Endorphina’s slots follow a recognisable structure: 5 reels, 10 to 100 lines, a free-spins round triggered by scatters, and a card-colour or card-rank gamble after wins. The art style uses saturated colours and caricatured characters, and many titles are themed on crypto, Asian festivals, fruit machines or mythology.
- Gamble feature: after a win, the player can risk it on a card guess to double it. This keeps RTP unchanged in expectation but raises variance. Some casinos disable it.
- Bonus buy: available in newer titles in markets that allow it. Our bonus buy guide explains the cost and RTP of bought features.
- Classic fruit formats: the Hell Hot and 2022 Hit Slot ranges use fixed-line fruit layouts with multiplier wilds, aimed at players who prefer short, simple rounds. See classic vs video pokies.

Maths profile
Most Endorphina slots are set at around 96% RTP, with volatility ranging from medium (fruit titles) to high (feature titles with bonus buys). Like most suppliers, Endorphina can deliver alternative RTP configurations for operators, so the figure shown in the game’s information screen is the one that applies. Our guide on how to check a game’s RTP shows where to find it, and RTP explained covers what RTP means over a single session.
Crypto focus
Endorphina was an early supplier to Bitcoin casinos and still has a strong presence at crypto-first operators. Satoshi’s Secret is the clearest example, and many Endorphina games can display stakes in cryptocurrency when the casino’s wallet runs in BTC or other coins. Our page on crypto casinos explains how currency and wallet settings affect gameplay and withdrawals.
Bonus play and Endorphina games
Two Endorphina features interact with bonus terms. First, the card gamble: many casinos prohibit gamble features while a bonus is active, and using one can void bonus winnings. Second, the bonus buy: buying a feature with bonus funds is often banned or counted as a breach of the maximum-bet rule. Before playing Endorphina slots with a bonus, read the restricted-games list and the maximum bet rule. Fruit-format titles such as 2022 Hit Slot are generally the simplest choice for wagering because they have no gamble-heavy bonus round to trigger.
How Endorphina compares
| Provider | Active since | Licence | Portfolio | Known for |
|---|---|---|---|---|
| Endorphina | 2012 | MGA/B2B/404/2017 | 230+ | Crypto themes, fruit formats, card gamble |
| BGaming | 2012 (brand 2018) | MGA/B2B/785/2020 | 250+ | Provably Fair casual games |

Endorphina’s regulated-market approvals (Sweden, Denmark, Ontario, Alberta) are broader than many studios of similar size, which is a useful signal that its RNG and RTP disclosures have passed several independent reviews.
Availability for Australian players
Endorphina content is distributed directly and via aggregators to casinos licensed in Malta, Curaçao and Anjouan, among others. On this site, 2 reviewed casinos currently list Endorphina as a provider: Neospin and Cosmobet. The list is on casinos with Endorphina games. Other casinos may carry individual Endorphina titles through aggregators without listing the provider separately, so search the lobby by game name. Demos are available on Endorphina’s site and in most casino lobbies; a casino can still restrict a title by country after login.
