Endorphina API for casinos: Prague-made slots in your lobby
Endorphina is a slot studio founded in Prague in 2012, known for fruit classics with a risk game such as Lucky Streak 3 and Hell Hot 100, and for book slots like Book of Santa. SoftAggregator lets you offer them through one API and a seamless wallet, alongside 40,000+ games from 200+ providers.
Who is Endorphina?
Endorphina is a Czech game studio founded in 2012 in Prague that designs video slots for online casinos. Its catalogue leans on two families: straightforward fruit and hot-themed machines with a gamble option, and story slots with free spins and expanding symbols.
The studio has a habit of picking unusual themes. Satoshi's Secret, a cryptocurrency-themed slot, was presented at a Bitcoin conference in Prague and was the first Endorphina title with six reels. That mix of old-school machines and odd ideas gives the brand a distinct personality in a lobby.
Which Endorphina games do players ask for?
A handful of Endorphina titles do most of the work, and each attracts a slightly different player. The descriptions below are about feel, because that is what decides where you place them in the lobby.
Endorphina titles at a glance
Release year shown where the studio or its coverage publishes it
| Title | Style | Why players like it |
|---|---|---|
| Lucky Streak 3 (2019) | Classic fruit slot, around 96% RTP | Familiar symbols, an interactive risk game after wins, top win of 750x |
| Hell Hot 100 | Hot-themed video slot with 100 fixed lines | Many lines hit often, a wild and a risk game to push small wins |
| Book of Santa | Book slot with expanding-symbol free spins | High volatility and wins up to 5,000x in the feature |
| Satoshi's Secret | Six-reel crypto-themed slot | A curiosity title that stands out in a slot list |
The pattern is clear: Endorphina's regulars enjoy short, readable sessions on fruit machines, and the risk game gives them a choice after every win. Book of Santa and the other book games serve the opposite taste, with long waits and a feature that can multiply the stake many times.
How does the Endorphina risk game affect my wallet?
It does not require anything special. The gamble option is played inside the game, and your wallet only sees the resulting debits and credits, each with its own call_id and the round_id it belongs to.
What matters is to process each callback on its own merits. Deduplicate on call_id, book the amount in minor units (1.50 becomes 150), return the new balance, and never refuse a movement because of the informational type field.
The same logic covers free spins in Book of Santa: once the feature starts, winnings arrive as credits without new stakes. A credit that has no matching debit is expected behaviour, not an error.
What does the integration involve, step by step?
One API for everything, one callback for the money. The integration you build for Endorphina is the same one that serves the rest of the catalogue, so the effort pays back across every studio.
- Get keys. Sign up on /#signup; after approval, api_login, api_password and salt_key are issued in your operator backend.
- Read the catalogue. POST method=getProviderList, then getGameList. Endorphina games come back with id_hash, name, game_type slots, image and a play_for_fun_supported flag.
- Register players. createPlayer fixes each player's currency; choose it according to your market.
- Launch. getGame with the id_hash as gameid returns an iframe URL; getGameDemo opens fun mode for visitors.
- Settle. Your callback URL answers action=balance, debit and credit with HTTP 200 and error 0, 1 or 2. Requests are signed with md5(timestamp + salt_key) and expire after 30 seconds.
- Check. getPlayerHistory returns a player's rounds, newest first, one merged line per round, up to 500 per call.
Field names, sample payloads and the error table are all in the SoftAggregator docs. If you want the conceptual view first, the casino game aggregator API page explains how one catalogue and one wallet serve every studio.
Which markets and currencies fit Endorphina?
Endorphina's fruit machines suit markets where land-based classics shaped player taste, such as Central and Eastern Europe, the Balkans and Turkey, and they also travel well to Asian and African audiences who prefer simple rules. Each player bets in the currency chosen at createPlayer.
Among our native currencies, the relevant ones here are EUR, CZK, PLN, HUF, RON, BGN, RUB, TRY, BRL, MXN, ARS, INR, BDT, PHP and ZAR. Outside that set, your account can operate in USD or EUR while you convert amounts for your players; contact us to discuss your currency.
Why use SoftAggregator for Endorphina rather than a direct link?
Because a direct link gives you one studio, while the same effort with us gives you the whole catalogue. A mid-sized studio like Endorphina is rarely the only thing an operator needs, and managing it as a separate connection multiplies wallet specifications, reports and invoices.
- One integration, many studios: Endorphina sits next to other European slot studios, crash games, live tables and a sportsbook on one wallet.
- Several brands: each website has its own keys, callback URL and default currency; catalogue, credit and reporting are shared.
- Operator-side control: balances stay in your system, and a live credit bar with low-balance alerts shows your prepaid credit.
- Numbers you can act on: bets, wins, RTP% and GGR per game, player and period in real time.
- Quick start: launch in days, with 24/7 support on Telegram @mentionso or [email protected].
One caveat for the whole page: our catalogue and currency list move continuously, and the live state is always what getProviderList and getGameList return. For the slot-specific view of the catalogue, see the online slots API, or the broader game aggregator API overview.
Endorphina integration FAQ
Where can I get an Endorphina API for my casino?
Through SoftAggregator. You receive API keys in the operator backend after signup and approval, and Endorphina titles appear in getGameList under their provider key, ready to launch with getGame.
Does the Endorphina risk game work through the aggregator?
Yes. The gamble feature is part of the game itself. Whatever it adds to or takes from the player reaches your wallet through the ordinary debit and credit callbacks, each with its own call_id.
Which Endorphina slots should I launch first?
Operators usually start with Lucky Streak 3, Hell Hot 100 and Book of Santa, then add the rest of the catalogue. The first two bring classic players, the third brings book-slot fans who like a high-volatility feature.
Can Endorphina games run in Czech koruna or Polish zloty?
Yes. CZK and PLN are among our native currencies, as are EUR, HUF, RON, BGN, TRY and others. The currency is fixed per player at createPlayer.
Is Endorphina content playable on mobile through SoftAggregator?
Yes. Pass device=mobile to getGame and the game opens in its mobile layout inside your iframe.
Do I need a separate contract to add Endorphina?
No. One SoftAggregator operator account gives you the whole catalogue, Endorphina included, through a single integration.
