A studio that bolts a real-money storefront onto its game inherits a problem it never signed up for. The moment players can buy currency, trade items, and cash value back out, the game looks like a small casino to fraudsters, and the same attacks that hit gambling operators arrive at the studio’s door. Most game teams have no fraud function ready for that. Studios can borrow the defenses casinos already built.
The New Fraud Surface
Casino-style mechanics create casino-style risk. Loot boxes, in-game currency, and item trading turn a game into a place where money moves in and back out, which is exactly the environment fraud networks target. Fraud against gaming and gambling platforms rose by more than 60% in early 2024, and the iGaming sector averaged 64% year-over-year growth in fraud between 2022 and 2024. For studios, fraud and abuse can eat 10% to 20% of a marketing budget through stolen-card purchases and bonus abuse.
A storefront that moves real money is a financial product. Fraudsters treat it as one immediately, and it needs active defense for as long as it runs, well beyond launch day. Regulators and banks now treat studios with cash-out economies much like gambling operators, which raises the compliance stakes alongside the fraud ones.
Account Takeover and Stolen Credentials
The most direct attack is the account takeover. A fraudster who buys leaked passwords logs into a real player’s account, then spends the stored card or sells the account’s items for cash. The player blames the studio, files a chargeback, and warns other players. One breach somewhere else becomes the studio’s fraud loss, because players reuse passwords across sites and a leak at an unrelated service hands attackers working logins for the game.
Stored payment details make gaming accounts a rich target. The defense starts with login security, step-up authentication on risky logins and an alert when an account is reached from a new device, the same controls a bank uses to guard a balance.
Borrowing the Casino Stack
Many studios skip building fraud tooling from scratch and adopt the same infrastructure casinos run. A payment gateway for online gambling already bundles card processing with fraud scoring and dispute handling tuned for high-risk, high-frequency play. Plugging into that kind of stack gives a game studio defenses that took the gambling industry years to refine.
A shared fraud network is part of the value. A card or device flagged at one operator on the same platform is flagged for everyone, so a new studio benefits from years of other companies’ data on its first day. The cost is some loss of control and a revenue share with the provider. The gain is a fraud operation on day one instead of after the first expensive attack.
Bonus Abuse and Multi-Accounting
Promotions are a magnet for abuse. Fraudsters use emulators and scripts to spin up dozens of fake accounts, each claiming a sign-up bonus or referral reward, then funnel the proceeds into one wallet. The studio pays out real money for players who do not exist.
Two cheap controls blunt most of this. A challenge test at account creation stops the simplest bots, and velocity checks count how many accounts or charges come from one device in a short window, so a script opening account after account trips a limit. A device fingerprint then ties those accounts back to a single machine even when the emails and cards differ.
Laundering Through In-Game Currency
Laundering is the quieter and often larger risk. A criminal buys in-game currency or loot boxes with stolen cards. The assets then move between accounts and sell on third-party markets for clean cash. Small purchases keep each step under the radar, and randomized loot boxes help because their contents make values hard to trace. The route crosses borders easily and leaves little trace, which is why financial-crime researchers now track gaming as a laundering vector.
The control here is the one gambling adopted against money laundering: know-your-customer checks and transaction monitoring. Verifying identity at the cash-out stage and watching for the buy-transfer-sell pattern turns an open route into a closed one.
The Secondary Market Problem
Fraud follows liquidity. Stolen game currency and rare items only matter to a thief if there is somewhere to sell them, and a large secondary market does exactly that. Third-party sites buy and resell accounts and in-game currency for real money, usually outside the game’s own rules. That market sets the price of every hacked account and every laundered loot box, and it is why a game with a thin economy attracts little fraud while a game with a deep one attracts a lot. Studios that allow or ignore real-money trading are funding their own attackers. The ones that fight it choke off the demand that makes the rest of the fraud worth attempting.
Layered Fraud Defenses
No single check stops fraud, so casinos stack several. Device fingerprinting links suspicious activity back to one machine and exposes the credential stuffing runs that feed account takeover, since the same device keeps appearing across stolen logins.
Behavioral biometrics add another layer by reading keystroke dynamics and mouse movement to tell a real returning player from an impostor on the same login. Velocity rules catch the automation. Each layer is weak alone and strong in combination, because a legitimate player passes all of them while a fraudster fails at least one.
Layering matters for a second reason. A single strict rule blocks fraud and frustrates real buyers in equal measure, while combined signals let a known, well-behaved account through and reserve friction for the accounts that earn it. Over-blocking is its own cost, because a good player wrongly refused at checkout rarely comes back.
A Question of Friction and Trust
The hard part is deciding how much friction to spend. Every check that stops a fraudster also asks something of an honest player, and a game that feels like a bank at checkout loses the casual buyer it depends on. Casinos have spent years tuning that balance, and studios now adopting casino-style payments inherit the same problem. The studios that handle it well treat fraud control as a product decision and measure the good players they keep as carefully as the fraud they block. The question they have to keep answering is easy to ask and hard to meet: how do you hold the doors open to real players while closing them to everyone else?
