Nocturn Sport for Sweepstakes: the Sweepstakes Sportsbook

A sweepstakes casino with only slots leaves its sports fans with nowhere to go. Nocturn Sport for Sweepstakes adds a full social sportsbook that runs on Gold Coins and Sweep Coins, ticket by ticket.

Updated October 29, 2026

Sweepstakes brands have grown fast on casino content, but sports betting has mostly stayed out of reach for them. Standard sportsbooks expect one cash wallet per player; sweepstakes players hold two coins and choose which one to play. Nocturn Sport for Sweepstakes is a separate product line built around that second model. The odds, markets and live betting are the same ones operators already get from Nocturn Sport. The difference is how a ticket is paid for and paid out.

This page walks through the whole picture from the operator's side: what the two coins mean on a bet slip, how a ticket is priced and settled with real numbers, which sports and markets players can open, how the sweepstakes betting software plugs into an existing platform, and which parts of the sweepstakes rules stay with the brand. If you only need the short version, the FAQ at the bottom covers the questions operators ask first.

Gold Coins and Sweep Coins: two coins, one bet slip

• Gold Coins (GC) are the entertainment coin. They have no cash value and are never exchanged. Each brand decides how many Gold Coins come with a pack.
• Sweep Coins (SC) are the promotional coin. A pack bought for 20 USD comes with 20.00 SC: always one Sweep Coin per US dollar paid. Brands can also give them away through mail-in requests and daily bonuses, and set their own rules for prize redemption.

Before confirming a ticket, the player picks Gold Coins or Sweep Coins in the bet slip. A ticket is always in one coin only. Combos can't mix a GC selection with an SC selection, and the whole stake comes from the chosen balance.

In practice the switch sits right above the stake field. A player who taps GC sees the Gold Coin balance and Gold Coin limits; tapping SC swaps both to the Sweep Coin figures. The odds on the slip do not change with the coin, because the price of an outcome has nothing to do with what the player stakes on it. What changes is the balance that gets debited, the limits that apply and the coin in which the ticket will come back.

How a ticket works in GC and SC, with numbers

The mechanics are easiest to follow on a few concrete tickets. All odds below are decimal, and the figures are illustrations, not live prices.

A single in Gold Coins

A player holds 40,000 GC and 12.50 SC. They back the home side in a Premier League match at 2.40 and stake 5,000 GC. On confirmation the Gold Coin balance drops to 35,000 GC; the Sweep Coin balance stays at 12.50 SC and is not even read. If the home side wins, the ticket returns 5,000 × 2.40 = 12,000 GC, and the Gold Coin balance goes to 47,000 GC. If they lose, nothing more happens: the 5,000 GC were already taken when the ticket was placed.

A single in Sweep Coins

The same player now places a 2.00 SC ticket on an NBA total, over 221.5 points at 1.85. The Sweep Coin balance goes from 12.50 to 10.50 SC. A winning ticket returns 2.00 × 1.85 = 3.70 SC, which brings the balance to 14.20 SC. Sweep Coin amounts are handled to two decimals, the same precision the brand already uses for packs and redemption, so there is no rounding surprise between the slip and the balance.

A parlay in Sweep Coins

Three legs on a Sunday of NFL: a moneyline at 1.90, a spread at 1.75 and a total at 2.10. The combined price is 1.90 × 1.75 × 2.10 = 6.98, shown on the slip before the player confirms. A 1.00 SC parlay returns 6.98 SC if all three legs win. If any leg loses, the ticket loses. Every leg is in Sweep Coins because the ticket is; the slip simply will not accept a Gold Coin leg on an SC parlay.

A void, inside and outside a parlay

Say the game behind the 1.75 leg is postponed and voided. The parlay is not lost: the voided leg drops out and the ticket carries on as a two-leg parlay at 1.90 × 2.10 = 3.99, so a win now returns 3.99 SC, still in Sweep Coins. On a single, a void is simpler. The 5,000 GC stake from the first example would go straight back to the Gold Coin balance, and the Sweep Coin side would not move.

A resettlement

Occasionally a result is corrected after the ticket has been settled, for example when the official result of a match is amended. The ticket is then settled again on the corrected result, and any difference is posted in the coin of the ticket. If the 2.00 SC NBA ticket had been paid 3.70 SC and the correction turns it into a loser, the 3.70 SC are taken back from the Sweep Coin balance; Gold Coins are never used to balance a Sweep Coin correction, and the reverse holds too.

Settlement in the coin of the ticket

This is the rule that keeps a sweepstakes sportsbook clean: a ticket settles in the coin it was placed in, whatever happens to it.

• Won: the return is credited in Gold Coins for a GC ticket, in Sweep Coins for an SC ticket.
• Void or cancelled event: the stake goes back to the same balance it came from.
• Result corrected after settlement: the resettlement follows the same rule; nothing is ever moved from one coin to the other.

For the operator, this means every Sweep Coin in a player's balance can be traced back to a pack, a giveaway or a settled SC ticket, and every Gold Coin to a pack, a bonus or a GC ticket. When the redemption team reviews an account, the sportsbook history reads like the casino history: one line per movement, each tagged with its coin.

Sports and markets in the sweeps coins sportsbook

The full Nocturn Sport offer is available in GC/SC mode: football, basketball, tennis, ice hockey, American football, MMA and esports, among others. Markets include match result, handicaps, totals and correct score, with live betting where the event allows it. The full list of competitions is on the leagues page, and every market type is explained in betting markets explained.

For brands with a mostly American audience, the calendar is built around the big four and combat sports. The NFL carries the weekend from September, with spreads, totals and moneylines on every game. The NBA and the NHL fill weeknights through the winter, and the MLB season keeps a full slate of games running through the summer, when the other leagues are quiet. UFC cards add fight-night peaks on Saturdays. Baseball and boxing outside those leagues are covered as well, so the board never goes empty between seasons.

Live betting follows the same coin rules as pre-match. A player who opens an in-play market on a hockey game picks GC or SC on the slip exactly as before the puck drop; prices move with the game, and the coin chosen on the slip is the coin the ticket settles in. How in-play pricing behaves is covered in the live betting guide, and the maths of multi-leg tickets in the accumulator guide.

Stake limits are set per sport and per coin, so a brand can keep Sweep Coin tickets more conservative than Gold Coin play.

Sweepstakes betting software: API integration step by step

Sweepstakes betting uses its own API namespace and its own wallet calls, separate from the standard sportsbook integration. An operator already running Nocturn Sport keeps everything as it is and adds the sweepstakes calls on top:

• a balance call that returns Gold Coins and Sweep Coins together;
• packs configured by the brand, with the Sweep Coin amount always equal to the price in US dollars;
• bet, settlement and rollback calls that carry the coin of the ticket, with a unique transaction id so that a repeated call never pays twice;
• a clear refusal when the chosen balance is too low, without touching the other coin.

Here is the order in which a typical integration comes together.

1. Balance. When the sportsbook opens for a player, it asks the operator's wallet for both balances in one call. The answer carries the Gold Coin figure and the Sweep Coin figure side by side, and the bet slip shows whichever coin the player has selected.
2. Bet. On confirmation, the sportsbook sends a bet call with the stake, the coin of the ticket and a transaction id. The wallet debits that one balance and confirms. If the selected balance cannot cover the stake, the wallet refuses, the ticket is not placed, and the other coin is left exactly as it was.
3. Settlement. When the result is in, a settlement call carries the return and the same coin. A losing ticket settles at zero; a winner credits the amount to the balance named in the call; a void credits the original stake back.
4. Rollback. If a bet call is not confirmed, for instance after a timeout, a rollback call cancels it and restores the stake to its coin. Resettlements after a corrected result arrive as their own movements, again tagged with the coin.
5. Idempotence. Every call has a unique transaction id. The wallet stores it and answers a repeated call with the first result instead of debiting or crediting a second time. Networks drop packets on busy Sunday afternoons; this is what stops a retry from becoming a double payout.
6. Limits. Minimum and maximum stakes are configured per sport and per coin. A brand might allow large Gold Coin tickets on any football match while capping Sweep Coin parlays on lower-tier competitions.

The one rule that runs through every step is one coin per ticket. The coin is fixed when the ticket is created and travels with every later call for that ticket, so the wallet never has to guess where money belongs.

Identity checks, redemption minimums and play-through rules stay in the operator's back office. The same sportsbook can also be delivered as a white-label sportsbook or through the sportsbook API.

How sweepstakes rules are handled

Nocturn Sport provides the betting side: odds, markets, ticket acceptance and settlement in the right coin. Everything that makes the promotion a sweepstakes stays with the brand that runs it, and the sportsbook is designed so those pieces fit around it without changes.

• Official rules. Each operator publishes its own sweepstakes rules: how Sweep Coins are obtained, how they can be used and how prizes are claimed. The sportsbook follows the coin logic; the rules document belongs to the operator.
• Free entry. Players can receive Sweep Coins without buying anything, typically through a mail-in request (often called AMOE, alternative method of entry) or daily bonuses. Those coins are credited by the operator to the Sweep Coin balance and can then be used on SC tickets like any other Sweep Coin.
• Redemption. Turning Sweep Coins into prizes is handled entirely by the operator: minimum amounts, play-through, payout methods and timing. The sportsbook never redeems anything; it only reports SC stakes and returns to the wallet.
• Identity verification. Know-your-customer checks before a redemption are run by the operator, in the tools it already uses for the casino side.

Casino and sportsbook on the same two coins

Most sweepstakes brands want slots and sports under one account. Through SoftAggregator's sweepstakes catalogue, the casino side runs on the same Gold Coins and Sweep Coins, so players move from a slot to a football ticket without switching balance.

Who uses a social sportsbook on GC and SC

The same product fits several kinds of operator. What differs is mostly where they start from.

• A sweepstakes casino adding sports. The most common case. The coin wallet, packs and redemption flow already exist; the sportsbook connects to them through the sweepstakes calls, and the sports tab appears next to the slots lobby. Players who left on Sunday to watch football now have a reason to stay.
• A social casino. A brand running a Gold Coin economy can open the sportsbook in GC only, letting players follow their teams with entertainment coins, and add Sweep Coins later on the same integration if it chooses to run a sweepstakes promotion.
• A sweepstakes platform. Platform providers serving several brands can connect once and give each brand its own pack sizes, limits per sport and per coin, and branding. Every brand keeps its own wallet and rules.
• A new sports-first sweepstakes brand. A team launching a brand built around sport rather than slots can start from the white-label sportsbook, plug in the two-coin wallet, and add casino content from the shared catalogue when the brand is ready.
