Bulletproof Games API: land-based design craft in high-volatility online slots
Bulletproof Games was set up by people who spent years designing cabinets for betting shops and arcades, and it shows: its slots are tight, readable and built around one big moment. Through SoftAggregator you can add Lotus Warrior, Tiki Runner GigaBlox, Dragon Lore Gigarise and the rest of its range with the API and wallet you already use for every other studio.
Bulletproof Games at a glance
Bulletproof Games is a British slot studio founded in 2015 by Craig Ball and Michael Bullock, both formerly senior figures at Inspired Gaming Group. It develops games for land-based and online casinos and also works as a design consultancy for other suppliers, with Playtech and Leander among its clients.
Online, its catalogue is compact, a few dozen releases rather than hundreds, and leans heavily toward high volatility. That combination makes it a specialist choice: a studio you add to give feature hunters something distinctive, not to fill a lobby by volume.
Cabinet designers writing for the browser
Designing for a betting-shop cabinet teaches discipline. A player must understand the game in seconds, the feature must be visible from across the room, and the maths must hold up over millions of spins. Bulletproof carried that discipline online.
The result is slots that feel classic at first glance and modern once the feature lands: a clear base game, a single well-signposted bonus, and a payout ceiling that justifies the wait. Players coming from UK retail gaming recognise the rhythm immediately.
YG Masters and the Giga mechanics
In February 2022 Bulletproof Games joined Yggdrasil's YG Masters programme, which gives selected independent studios access to Yggdrasil's game technology and distribution. Two of Yggdrasil's signature mechanics then appeared in Bulletproof titles.
GigaBlox drops oversized symbols, up to several reels wide, onto the grid, which can cover whole sections of the screen in one go; Tiki Runner GigaBlox is the Bulletproof example. Gigarise makes the reels grow in height as the game progresses, increasing ways to win; Dragon Lore Gigarise uses it with a published maximum win of 15,000 times the stake. Tiki Runner GigaBlox goes further, with a maximum of 20,984 times the stake. If you also stock Yggdrasil itself, see our Yggdrasil API page.
Bulletproof Games titles worth pinning
Maximum wins as published for each game.
| Title or series | Style | What players come for |
|---|---|---|

| Tiki Runner series (incl. GigaBlox) | Island adventure, giant symbols | Huge single-screen hits; up to 20,984x in the GigaBlox edition |
| Dragon Lore Gigarise | Fantasy, rising reels | Ways that grow toward a 15,000x ceiling |
| Tempered Steel | Forged-metal theme | A crowd favourite among the studio's releases |
| Attack of the Zombees | Comic horror | Light-hearted theme with high-variance maths |
What Bulletproof content asks of your platform
The integration itself is identical to any other studio: our API lists and launches the games, and we call your wallet. What differs is the shape of the traffic. High-volatility slots with big ceilings produce many small losing debits and rare, large credits, and your wallet must be comfortable with both.
- Large integers. A 20,000x win on a meaningful stake is a big number in minor units. Check the size of the column that stores amounts.
- Credits with no debit. Free spins and bonus payouts may arrive without a debit in the same round. The
typefield (bet, win, bonus_fs) is informational; never reject because of it. - Retries and rollbacks. Repeat calls carry the same
call_id; answer with the original result. Rollbacks carryrb=1. - Clear answers. Always return HTTP 200. Use error 1 with the current balance when funds are short and error 2 for a bad signature or an unknown player.
Signature details (key = md5(timestamp + salt_key), timestamp within 30 seconds), the launch parameters of getGame and the history call getPlayerHistory are all described in the SoftAggregator API documentation.
Where to place Bulletproof in your lobby
Bulletproof works as a specialist shelf. Put its titles in a "high volatility" or "big win potential" row next to other feature-heavy studios, or in a "UK favourites" row for players who come from retail. Pair them with calmer games elsewhere in the lobby so every player finds the risk level they want.
Demo mode helps here: on titles flagged play_for_fun_supported, getGameDemo lets a visitor see a GigaBlox drop before depositing, which is often enough to convince them.
Direct deal or SoftAggregator for a specialist studio
A compact, high-volatility catalogue is hard to justify as a standalone integration. Through our casino game aggregator API, Bulletproof Games is one filter on a catalogue of 40,000+ games from 200+ providers, and the wallet callback you build once settles all of them.
Around that sit the tools that keep a casino running: prepaid credit with a live bar and low-balance alerts, real-time reporting of bets, wins, RTP% and GGR by game, player and period, and the option to run several websites on one account with separate keys, callbacks and default currencies. Players only ever see your brand. Casino and sportsbook can share the same platform and wallet, and most operators with a working wallet are live within days, with 24/7 help on Telegram @mentionso.
The game aggregator API pillar page goes deeper into catalogue structure and lobby categories across studios.
Currencies and audiences
Bulletproof's natural audience is British and European, with high-volatility fans everywhere. Native currencies relevant to them include GBP, EUR, SEK, NOK, DKK, PLN, CAD, AUD, NZD, BRL, MXN, INR and TRY. For currencies beyond that list we hold your account in USD or EUR and your cashier presents local amounts; tell us which one you need. Because our catalogue and currency set change continuously, getGameList and getCurrencies are the reference at any moment.
Bulletproof Games: operator FAQ
How can I offer Bulletproof Games slots in my casino?
Connect to SoftAggregator once, then filter getGameList on the Bulletproof Games provider key. Launch titles such as Lotus Warrior or Tiki Runner GigaBlox with getGame; every bet and win is settled through your seamless-wallet callback.
Is there a Bulletproof Games API?
Operators can use the SoftAggregator API to reach Bulletproof Games content. It is the same JSON endpoint and wallet protocol we use for every studio, so there is no dedicated Bulletproof protocol to implement.
Do GigaBlox and Gigarise games need special handling?
No. Giant symbols and rising reels are drawn and calculated by the game. Your wallet receives a debit for the spin and a credit for the result, like any other slot.
Are Bulletproof Games slots high volatility?
Most of the catalogue sits at the higher end of volatility, with maximum wins in the tens of thousands of times the stake on some titles. Expect long quiet spells and occasional large credits, and make sure your ledger stores big minor-unit integers.
Which currencies can I use for Bulletproof Games?
Each player keeps the currency chosen at createPlayer. Native options include GBP, EUR, SEK, NOK, CAD, AUD, NZD, BRL, MXN, INR, TRY and many more. If you need a different one, the account is held in USD or EUR and your side converts for the player; just contact us.
