4ThePlayer API: slots with timed bonuses, player-placed wilds and big portrait reels

Is there a 4ThePlayer API for operators?

Yes, in the sense that matters for a casino: 4ThePlayer games can be listed, launched and settled through the SoftAggregator API, with no separate studio integration. The same callback that pays out any other slot pays out a 4ThePlayer win.

The rest of this page explains why these games feel different to players, and what, if anything, that changes for your wallet. Short version: the novelty is inside the game, and your integration stays standard.

A young studio built by veterans

4ThePlayer was founded in 2018 in London by Andrew Porter, Chris Ash, Thomaz Scalzilli and Henry McLean, who between them had decades of experience in the gaming industry. They set out to be a challenger brand, competing on ideas rather than on release volume.

The approach earned recognition quickly. In 2022 the studio won the Innovation in Slot Provision award at the EGR B2B Awards, and in the same year it was named Outperforming Game Studio of the Year (small) at the CasinoBeats Game Developer Awards.

Why the numbered titles stick in players' heads

4ThePlayer names many of its games with a number: 3 Secret Cities, 4 Fantastic Fish, 6 Wild Sharks, 90k Yeti. It is a small branding trick, but it helps: players remember the titles, and a row of them in a lobby looks like a series.

Underneath, each game carries a different hook. 6 Wild Sharks lets players decide how aggressive the reels should be. 60 Second Heist turns the bonus into a race against the clock. 7 Elements rewards coming back on different days. The common thread is agency: the player does something, rather than only pressing spin.

Portrait mode and the phone lobby

Big Reel Portrait mode is one of the clearest reasons to feature 4ThePlayer for mobile traffic. On a phone held upright, the reels take most of the screen instead of sitting in a small landscape box with black bars above and below.

To get the benefit, launch with device=mobile, size your iframe to the full viewport height, and keep your own header or chat widget out of the lower part of the screen. The difference in comfort is visible on the first spin.

Wallet behaviour: time-based and choice-based features

None of the 4ThePlayer mechanics needs wallet-side logic. Win Time, WILD CHOICE and Future Power are all run by the game; your platform only sees signed GET callbacks for balance, debit and credit, with amounts in minor units.

• Timed bonuses. During a Win Time bonus the game may play many spins quickly. They pay as credits, often without a debit in the same round, so accept credits on signature and player, not on a matching bet.
• Player choices. When a choice changes the cost of a spin, the debit amount changes too. Do not assume a constant stake per session.
• Returning features. Calendar-based progress is stored by the game, not by your wallet.
• Reliability. Deduplicate on call_id, apply rb=1 rollbacks once, and always answer HTTP 200 with error 0, 1 or 2 as documented.

Full parameter lists and signature rules (md5(timestamp + salt_key), 30-second window) are in the SoftAggregator API docs.

Going live with 4ThePlayer

1. Apply through the signup form and receive your keys in the operator backend after approval.

3. Load getGameList, keep the 4ThePlayer titles, and build a series row from the numbered names.
4. Create players with createPlayer in their market's currency.
5. Launch with getGame, or getGameDemo for fun play where the game allows it.

One integration for boutique innovators

Studios like 4ThePlayer are exactly why operators use an aggregator. Few casinos would sign and integrate a small innovative studio on its own; through our casino game aggregator API it comes with the rest of 40,000+ games from 200+ providers, settled by the callback you already have.

The front is white-label, so players see your casino, and a sportsbook can share the same wallet. Integration support answers at any hour on Telegram @mentionso and [email protected]. For the broader logic of consolidating studios, read our game aggregator API overview.

Markets and currencies

4ThePlayer's audience is strongest in the UK and Europe, with its mobile focus making it a good fit for phone-heavy markets elsewhere. Native options include GBP, EUR, SEK, NOK, DKK, CAD, AUD, NZD, BRL, MXN, INR and ZAR. If your players use another currency, we keep the account in USD or EUR and your platform converts; ask us about it. Studios and currencies are added all the time, and the API always shows the current list.
