USA sweepstakes aggregators: one connection, many studios, two coins

An aggregator can fill a sweeps lobby in weeks. Whether it keeps Gold Coins and Sweep Coins straight is the part worth checking.

Updated October 29, 2026 · by the editorial team

A sweepstakes aggregator is a B2B company that connects a sweepstakes casino to games from many studios through one API, passing the player's chosen coin, Gold Coins or Sweep Coins, through every launch, bet, win and rollback. Instead of signing and integrating ten studios, the operator signs one contract and does one technical integration.

Why sweepstakes operators use an aggregator

Three reasons come up in almost every operator conversation.

• Speed. One integration instead of many. Each direct studio connection means its own sandbox, its own certification of your wallet calls, and its own contract.
• Replacement capacity. When content supply changed in 2025 and some large studios stepped back from US sweepstakes, operators with an aggregator could swap titles from inside one catalogue. Operators with direct deals had to start new ones.
• One coin model to test. If the aggregator enforces GC/SC rules at its own layer, the operator tests the coin logic once, not once per studio.

The third point is the one to verify, not assume. Some aggregators pass the coin to studios that support it natively; others convert at the edge for studios that only know one currency. Both can work. The edge-conversion model is where cross-coin bugs hide.

A small example of what can go wrong

A player stakes 2.00 SC on an aggregated slot. The studio behind it only understands "credits", so the aggregator maps the round to SC. The round crashes mid-feature. The studio sends a rollback that references only the round ID. If the aggregator has lost the coin mapping, which can happen after a restart or a cache expiry, it may refund 2.00 into the default balance, usually GC. The player is down 2.00 SC and up 2.00 GC, worth nothing redeemable. Ask every aggregator how its rollbacks find the original coin.

USA sweepstakes aggregators ranked (October 2026)

1. Nocturn Play Top pick

   What it is: a game studio with its own sweepstakes product line, ranked here because it gives operators what most look for in an aggregator, a broad multi-format catalogue behind one connection, without an extra conversion layer. The two-coin logic lives at the source. Its slots, crash, instant, keno and bingo games run on GC and SC through a separate sweepstakes launch entry point; each round stays in its coin, the win is paid in that coin, and a rollback returns to it.

   Why first: there is no edge conversion to go wrong. The scenario above cannot occur when the studio itself tracks the coin per session and refuses stakes above the chosen balance. The 52 titles cover formats that most aggregated sweeps catalogues are thin on, such as fish shooters, 90-ball bingo like the Comet Bingo 90-ball room, keno and crash titles like Lumen Drift, a 10,000× crash game. You can browse every Nocturn Play title in one catalogue. Sweeps mode is switched on per operator, and the operator keeps its own rules, redemption and player checks.

2. SoftAggregator

   What it is: a casino game aggregator with a dedicated sweepstakes line. According to its sweepstakes casino games API page, the line covers slots, crash and instant games and a sportsbook on GC and SC, through "one dual-balance API that any sweepstakes casino platform can connect". It runs on its own API namespace, separate from the standard wallet, so existing operators keep their current integration and add the sweepstakes calls.

   On coin handling, the page states that GC and SC are separate balances; one balance call returns both (GC as a whole number, SC with two decimals); the chosen coin is passed at launch and on every bet; wins are credited in the round's coin; bonus features pay in the coin of the triggering round even if the player switches coins mid-feature; and rollbacks reference the original transaction. A bet above the chosen balance is refused. Free rounds can be configured per operator on request, and the sandbox tests both coins end to end. The sportsbook it lists for sweepstakes is Nocturn Sport, covering football, basketball, tennis, ice hockey, MMA and esports. The page says official rules, AMOE, redemption, play-through and KYC stay with the operator, and that the company never needs player documents. It gives no sweepstakes-specific game or provider count.

3. Alea

   What it is: a large aggregator (23,000+ games from 170+ providers overall). Alea describes its sweepstakes-ready portfolio as 5,000+ titles from 50+ providers, unveiled at SBC Summit Americas (date unverified), and has a partnership with CatoriTech. Best for operators who want the biggest sourced sweeps catalogue in one contract.

4. Hub88

   What it is: an aggregator with the clearest public sweeps reference in this list. Its US sweepstakes debut was with Legendz, a social casino and sportsbook, reported around December 2024 as live in 43 states with 1,000+ games, including titles from Playson, Kalamba and Booming.

5. SOFTSWISS Game Aggregator

   What it is: the largest raw library we found, 27,800+ games from 280+ providers according to sponsored SiGMA coverage that positions it for sweepstakes and social casinos. How many of those titles are cleared for coin play, and how coins are mapped, is not public.

6. Sweepium

   What it is: a white-label platform with a built-in game aggregator, aimed at US sweeps brands. Provider counts differ by source (50+ or 80+). Backed by Xanada Investments since June 2025. Best when you want the platform and the aggregator from one vendor; see our platform guide for that route.

Not ranked: Slotegrator, which a CB Insights listing describes as "expanding into sweepstakes casino solutions"; we found no sweepstakes product launch. EveryMatrix appears only in regulated US coverage in our research.

Integration steps with a sweepstakes aggregator

The order below reflects the call flows that Nocturn Play and SoftAggregator publish on their sweepstakes pages. Other aggregators may differ in naming, not in substance.

1. Request sweeps access. The supplier enables sweepstakes mode for your operator code. Until then, coin launches should be refused.
2. Balance. Your wallet returns GC as a whole number and SC with two decimals.
3. Launch. Your lobby passes player, game, language and coin. Decide what happens when coin is missing (GC is the safe default).
4. Bet and win. Each call carries player, round, amount, coin and a unique transaction ID.
5. Rollback. References the original transaction and returns the stake to its original coin.
6. Idempotence tests. Replay a bet, a win and a rollback with the same ID. Each must return the first result and change nothing.
7. Catalogue import. Pull the list of titles cleared for sweeps, by category, and map them into your lobby filters.

A practical tip: run step 6 against at least three different studios inside the aggregator, not just one. If the aggregator converts at the edge for some studios, that is where a difference will show.
