Sweepstakes
Gold Coin & Sweeps Coin platforms
Sweepstakes-model platforms give away free Gold Coins for play and separately award Sweeps Coins that can be redeemed for cash or prizes without a purchase. That "free to enter, real prize" structure is exactly what draws multi-accounting: every new account is a fresh allotment of Sweeps Coins, and unlike a deposit-funded casino account, there's no payment friction stopping someone from opening a dozen of them.
In practice, this shows up as a small number of real operators running many accounts through referral bonuses, daily login bonuses, and no-purchase-necessary mail-in entries, then routing the redemptions to a handful of shared destinations. The individual accounts rarely look suspicious in isolation — each one plays a plausible amount, claims a plausible number of bonuses, and waits a plausible interval before redeeming. The tell is only visible once you connect the accounts to each other.
What we watch for
- Redemption requests from otherwise-unconnected accounts converging on the same payout method, prepaid card, or mailing address
- Referral chains that loop back to a small seed set of accounts within two or three hops
- Daily-bonus claim timing that's synchronized to the second across accounts with no other visible connection
- Mail-in "alternate method of entry" submissions arriving in batches with near-identical formatting or handwriting patterns

iGaming
Casino & sportsbook operators
Licensed iGaming operators compete hard on welcome bonuses and reload offers, which makes bonus economics the main attack surface. The two patterns we see most: bonus cycling, where a group of linked accounts each claim a welcome bonus, satisfy the wagering requirement with minimal-variance bets, and withdraw the residual value; and matched betting, where an abuser backs and lays the same outcome across a bonus account and a linked exchange or sportsbook account to extract close to risk-free value from free-bet promotions.
Affiliate fraud is a distinct third pattern worth calling out separately: an affiliate refers accounts to themselves, or to a small ring they control, to collect CPA payouts on players who were never going to be organic depositors.
What we watch for
- Minimal-variance bet patterns immediately following a bonus credit, repeated identically across a cluster
- Opposing bets on the same event placed from accounts sharing a device or payment instrument
- Affiliate-referred accounts whose device and network fingerprints overlap with the affiliate's own login history
- Deposit-then-immediate-bonus-claim sequences with no organic play in between, repeated across many "new" accounts

Skill-gaming
Real-money skill-based platforms
Skill-gaming abuse tends to center on the entry fee and the matchmaking pool rather than a deposit bonus. Smurf accounts — new accounts deliberately built to look like beginners — are used to get matched against genuinely weaker opponents and win disproportionately. Collusion is the inverse problem: two accounts that are actually the same operator or a coordinated pair, "competing" against each other in a way engineered to guarantee one side wins, often to launder entry fees or extract a promotional match bonus.
Entry-fee bonus abuse — opening disposable accounts purely to claim a first-entry-free or deposit-match promotion, playing the minimum required, and abandoning the account — rounds out the pattern set, and is often the highest-volume of the three even though it's the least sophisticated.
What we watch for
- Win-rate anomalies concentrated against a small set of "opponent" accounts rather than distributed across the matchmaking pool
- Session timing overlap between paired accounts that's inconsistent with two independent players
- New accounts whose skill rating trajectory doesn't match typical beginner progression curves
- Entry-fee promotional claims followed by immediate account inactivity, repeated at volume from related devices

DFS
Daily fantasy sports operators
Daily fantasy sports adds a wrinkle the other verticals don't have: information sharing between accounts that are formally "competing" against each other in the same guaranteed prize pool contest. A lineup syndicate — a group of accounts controlled by, or coordinating with, the same operator — can split entries across many overlapping lineups to dramatically increase the odds that at least one of them lands in the money, then share the pooled winnings afterward. That's a different problem from deposit-bonus stacking, where the goal is simply extracting promotional value across linked accounts rather than gaming the contest structure itself.
Multi-entry abuse compounds this in large-field guaranteed prize pool contests, where platform rules typically cap entries per person but a syndicate can exceed that cap by distributing entries across accounts that look, individually, like ordinary single-entry players.
What we watch for
- Lineup construction that's suspiciously complementary across "unrelated" accounts in the same contest, rather than independently optimized
- Entry counts per real-world identity that exceed platform caps once accounts are correctly clustered
- Deposit-bonus claims distributed evenly across a cluster with no corresponding independent play pattern
- Prize withdrawals from multiple "competing" accounts converging on one payout destination after a contest resolves
