Big Time Gaming API: the Megaways originals, integrated in days

Megaways in one paragraph

Megaways is a random reel modifier: on each spin, every reel shows between two and seven symbols, so the number of winning ways changes from spin to spin and can reach 117,649 on the classic six-reel layout. Most Megaways games add cascading wins, where winning symbols disappear and new ones fall in, so a single paid spin can produce several wins.

Big Time Gaming introduced the mechanic and later opened it to other developers through commercial agreements. That is why players meet Megaways versions of games from studios as different as Red Tiger, Blueprint Gaming and Pragmatic Play. For an operator, a Megaways section in the lobby is one of the easiest themed categories to build.

The studio behind it

Big Time Gaming was founded in Sydney, Australia, in 2011 by Nik Robinson, a designer with a long background in land-based slot machines. The studio stayed deliberately small and released few games, each with a strong mathematical hook.

Bonanza, released in 2016, turned Megaways into a phenomenon: a gold-mine theme, cascading reels and an unlimited free-spin multiplier. Evolution acquired Big Time Gaming in 2021, which placed it in the same group as NetEnt and Red Tiger. BTG has continued to experiment beyond Megaways, with mechanics such as Megaclusters, but its identity is still the high-variance, big-ceiling slot.

What players are really buying with a BTG spin

Players choose Big Time Gaming for the ceiling. The base game is often quiet, but the free spins can snowball: each cascade raises the multiplier, and the multiplier does not reset between spins in several titles. That creates the rare, huge wins that end up in clip compilations and forum threads.

The feel is therefore closer to a lottery ticket with texture than to a steady entertainer. Sessions are shorter and more emotional than on a low-volatility classic, and BTG fans are the players most likely to use a feature buy on games that offer one. Operators usually place BTG in a "high volatility" or "Megaways" row rather than on the front page next to gentle titles, so each player finds the risk profile they came for.

Callback traffic from Megaways: what to expect

Megaways traffic has two signatures: long cascade chains inside a single round and occasional very large credits. Neither needs special code, but both expose weak wallets.

• One debit, many wins, one settlement. A cascade chain belongs to one round. The player is debited once and the total comes back as a credit tied to the same round_id.
• Credits without a debit. Free-spin rounds usually pay credits with no debit in the same round. The type value (for example bonus_fs) is informational; never reject on it.
• Big numbers. Amounts are integers in minor units, so a large win on a high stake can be a long integer. Store it in a column that will not overflow.
• Feature buys. Where a title sells direct entry to the bonus, it arrives as a single debit worth a large multiple of the base bet. If the player lacks funds, answer error 1 with the current balance.
• Retries. A network retry reuses the same call_id. Return the original result and do not move money twice; a rollback is flagged with rb=1.

Signature checks, error codes and sample payloads are documented in the SoftAggregator API docs. When a player questions a big Bonanza win, getPlayerHistory gives one merged line per round, newest first, with up to 500 entries per call.

Launching BTG through SoftAggregator

1. Get your keys: sign up, get approved, and read api_login, api_password and salt_key in the operator backend.
2. Read the catalogue: getProviderList gives the Big Time Gaming key; getGameList gives each title's id_hash, image and demo flag.
3. Create players in their own currency with createPlayer.
4. Open the game: getGame returns an iframe URL; add homeurl so the exit button brings the player back to your lobby.
5. Offer a trial: getGameDemo opens fun mode on titles flagged play_for_fun_supported, handy for letting visitors feel a Megaways cascade before they deposit.

That is the entire BTG-specific setup. Because the same flow launches every studio in our casino game aggregator API, a Megaways category can mix BTG originals with Megaways titles from other studios without a line of extra code.

Direct with BTG vs one aggregator connection

A direct studio integration makes sense only if Big Time Gaming is your entire strategy. BTG releases relatively few games, so on its own it cannot fill a lobby; the value comes from pairing it with the wider Megaways ecosystem and with low-variance studios that balance it.

Through the game aggregator API you also keep everything else that makes a small team fast: prepaid credit with a live bar and alerts, one backend for several brands with separate keys and callbacks, a white-label front where only your brand appears, and a sportsbook on the same wallet if you want one.

Currencies for Megaways players

BTG audiences cluster in the UK, the Nordics, Central Europe, Canada, Australia and New Zealand, with a growing following in Latin America. Players there can be created natively in GBP, EUR, SEK, NOK, DKK, PLN, CZK, CAD, AUD, NZD, BRL or MXN, and each player keeps that currency for life.

Anything else is handled in USD or EUR on our side, with your platform doing the local conversion; just ask us about the currency you need. Our catalogue and currency list move all the time, and the API (getGameList, getCurrencies) always returns the current state.
