Thunderkick API: bring Esqueleto Explosivo and Pink Elephants to your players through one integration

Where Thunderkick fits in a casino lobby

Thunderkick fills the gap between casual and hardcore: its games are playful and highly illustrated, and its volatility ranges from gentle to steep. Put them in your lobby when you want titles that feel distinctive without scaring off newer players.

The studio was founded in Stockholm in 2012 by a group of former NetEnt developers, at a time when the Swedish capital was turning into a hub for online casino game design. Its name became known with Esqueleto Explosivo in 2014, a Day of the Dead slot with a skeleton mariachi band, and it has kept its hand-drawn, humorous style ever since.

Two games that show the range

Esqueleto Explosivo and Pink Elephants sit at opposite ends of the Thunderkick scale, and between them they explain why the studio suits so many player types.

What Thunderkick traffic looks like on your callback

Thunderkick games generate a steady stream of small transactions, especially on the low-volatility titles. Your wallet should answer fast and consistently, because a player on Esqueleto Explosivo can spin for a long time at a modest stake.

Each spin brings a debit, and each winning spin a credit, sent as GET requests to your callback URL with action=debit or action=credit. Amounts are integers in minor units, so a 1.00 stake reads 100. Use call_id to make sure nothing is ever booked twice, use round_id to tie the win to its stake, and apply rb=1 as a reversal of the transaction it refers to. Free spins inside Pink Elephants arrive as credits that may not have a debit of their own; that is expected, and the informational type value must not be used to refuse them.

• Balance request: return the player's current funds.
• Debit accepted: error 0 and the new balance.
• Not enough money: error 1 and the current balance.
• Bad signature (md5 of timestamp + salt_key, 30-second window), unknown player or internal failure: error 2.
• Always HTTP 200, whatever the error code.

All of this is spelled out, with parameter tables, in the SoftAggregator API docs. The same callback serves every game type in our catalogue, as described on the casino game aggregator API page.

Currencies for Thunderkick players

Thunderkick's audience is spread across Northern and Western Europe, Canada, Latin America and Asia-Pacific. Each player is created in one currency that stays fixed.

Relevant native currencies include SEK, NOK, DKK, EUR, GBP, CAD, AUD, NZD, BRL, MXN, JPY, KRW, THB, PHP and USD. When your market works in a currency that is not on our native list, the account can still run in USD or EUR, with conversion handled by you; reach out and we will look at your currency together. The studio list and currency coverage are refreshed all the time, and the API (getProviderList, getGameList) always reflects the current state.

Thunderkick plus the rest, on one account

SoftAggregator gives you Thunderkick and 40,000+ games from 200+ providers behind the same API, with prepaid credit, a live credit bar, low-balance alerts and one reporting screen.
