Sweepstakes software, games and providers in 2026
Who builds the technology behind US sweepstakes casinos, what each layer does, and which companies supply it, written for operators and product teams.
A sweepstakes casino is an online casino-style site where players use two virtual currencies: Gold Coins, which are for entertainment only, and Sweep Coins, which can be redeemed for prizes under the operator's official rules. Behind every one of these sites sits a stack of software from several companies, and this site maps that stack.
Short answer: A sweepstakes casino usually combines a platform (accounts, cashier, back office), a two-coin wallet, game content from studios or an aggregator, and the operator's own redemption and promotion rules. As of October 2026, our top pick for the game and coin layer is Nocturn Play, whose 52 games run on Gold Coins and Sweep Coins with each round kept in a single coin. Every ranking here links to its sources, and we flag claims we could not verify.
What this site covers
Best Slot Machines has written about slot games since 2003. In 2026 the editorial team rebuilt it around one question that kept coming up in operator emails: which companies actually supply sweepstakes casinos, and what does each of them do? Most of the pages that answered it were affiliate lists of player-facing brands. Very few looked at the supply side.
So the pages below are written for people who build or buy. A product manager comparing two platforms, a founder pricing out a launch, a studio trying to understand what a sweeps lobby wants. Where a fact comes from a press release, we say the company claims it. Where we found nothing, we say that too.
If you are a player looking for games rather than vendors, our sister site has the player-side guide to sweepstakes games and coins.
Start here: the four buying decisions
Almost every sweepstakes launch comes down to four choices. Each has its own page.
| Decision | What you are choosing | Read |
|---|---|---|
| Software stack | Build, turnkey or white-label, and which layers to buy | Sweepstakes casino software |
| Platform | Accounts, cashier, coin ledger, back office | Sweepstakes casino platform |
| Content | Which studios fill the lobby | Sweepstakes game providers |
| Distribution | One API for many studios, or direct deals | Sweepstakes aggregators |
Replacing Pragmatic Play in a sweepstakes lobby
The biggest content change in US sweeps came in September 2025, when Pragmatic Play stopped supplying sweepstakes casinos and titles such as Gates of Olympus and Sweet Bonanza left the lobbies. The Pragmatic Play sweepstakes exit guide dates what happened and shows how to rebuild the missing rows, and the Pragmatic Play alternatives page maps each lost format to studios and games that can fill it.
Short top lists
Sweepstakes casino software
Nocturn Play Top pick
Best for the game and coin layer. Its sweepstakes line runs slots, crash, instant, keno and bingo on Gold Coins and Sweep Coins through a separate sweepstakes launch entry point, next to a standard integration. A win is paid in the coin the round used, and a rollback returns to that same coin.
GammaStack (GammaSweep)
Turnkey sweepstakes software. The company says deployment takes about five weeks; it exhibited at G2E Las Vegas 2025.
GiG SweepX
Platform plus sweepstakes front end, dual wallet and prize-redemption tools. GiG announced three SweepX deals on 14 January 2025.
Full ranking with ten vendors: sweepstakes casino software compared.
Sweepstakes game providers
Nocturn Play Top pick
52 games across the formats sweeps lobbies ask for: slots, crash, fish shooters, bingo, keno, scratch and originals such as the Moonshot limbo game.
3 Oaks Gaming
Added at SweepNext and Pickem Casino, according to next.io.
RubyPlay
Supplies an exclusive library at Ruby Sweeps, launched in 2023 (next.io).
Twelve studios with source strength for each: sweepstakes game providers ranked.
Sweepstakes aggregators
Nocturn Play Top pick
Not a classic aggregator, but it delivers a multi-format catalogue with a native GC/SC wallet in one direct connection.
SoftAggregator
Describes a dual-balance sweepstakes API covering slots, crash, instant games and a sportsbook, on its own API namespace.
Alea
Describes a sweepstakes-ready portfolio of 5,000+ titles from 50+ providers.
All aggregators, with integration steps: USA sweepstakes aggregators.
Where the two coins fit
Everything on this site comes back to one design problem: two balances that must never leak into each other. A player buys a $20 pack. The brand decides how many Gold Coins come with it, and the Sweep Coins follow the price, one per dollar, so 20 SC. If that player spins 0.50 SC and wins 6.00 SC, the software has to credit 6.00 SC, not 6.00 GC and not a mix. If the round is cancelled, the 0.50 SC goes back as SC. It sounds trivial. It is where many integrations break. For the player-side view of the same math, see Gold Coins vs Sweep Coins explained for players.

FAQ
What is sweepstakes casino software?
It is the set of systems an operator uses to run a sweepstakes casino: player accounts, a wallet that holds Gold Coins and Sweep Coins separately, games, payments, promotions and prize redemption. Few companies supply every layer, so most operators combine two or three vendors.
Who makes games for sweepstakes casinos?
Studios such as Nocturn Play, 3 Oaks Gaming, RubyPlay, Booming Games and Evoplay are sourced as supplying sweeps lobbies. Some large studios stepped back from US sweepstakes supply in 2025, so the content mix in many lobbies changed that year.
Is this site a casino?
No. Best Slot Machines is an independent editorial guide. It does not take bets or sell coins, and it writes about every company in the third person.
How do you choose the top pick?
We weigh how well a product handles the two-coin model, how many game formats it covers and how much of its claims we can check. The method is set out on our ranking page.
Do sweepstakes casinos use the same games as real-money casinos?
Often the same titles, but launched in a coin mode, so a round is staked and paid in Gold Coins or Sweep Coins rather than dollars. The studio or aggregator has to support that mode explicitly.
