Guide to Bonus Abuse in iGaming: How to Detect & Prevent

The iGaming industry is booming, with billions participating in online betting and projections estimating its value will soar to $370 billion by 2032. While this growth presents incredible opportunities, it also brings significant challenges, particularly the rise of bonus abuse.

What Is Bonus Abuse?

Bonus abuse, often referred to in the context of online gaming or gambling, is the practice in which individuals exploit promotional offers intended for new users and provided by platforms to gain unfair advantages or profits. It is a sophisticated form of fraud that leverages vulnerabilities in operators’ processes that enable the exploitation of promotional incentives designed for new players.

This unethical behavior, also referred to promo abuse, multi-accounting or bonus hunting, targets various bonus offers, extra funds, sign-ups, free spins, no-deposit bonuses and other incentives designed to attract new users or reward loyal customers.

Bonus abusers manipulate these promotions through strategies like creating multiple accounts, collaborating with others or employing betting patterns that minimize risk while maximizing the benefit from these bonuses. Such activities violate the terms and conditions of the platforms and can lead to account suspension, forfeiture of winnings, and, in some cases, legal action. In essence, bonus abuse undermines the intended spirit of promotional offers, creating an uneven playing field and potentially causing financial and reputational damage to the service providers.

How Bonus Abuse Fraud Works in iGaming

Fraudsters often create multiple fake identities to repeatedly claim bonuses intended for first-time users or engage in practices such as multi-accounting and using advanced technologies like VPNs or Tor browsers to conceal their activities, making it challenging for operators to track and stop them.

While the methods of bonus abuse vary, including strategies like arbitrage betting, cross betting, bonus hunting and chip dumping, all of them threaten the financial stability of gaming platforms and the fairness of the industry. Central to the issue lies inadequate online identity verification processes that fail to detect signs of fraudulent activities, allowing abusers to exploit these systems repeatedly. 

Operators are countering this threat with stringent terms and conditions, keen surveillance of player activities and adherence to strict regulatory standards, as well as implementing complex bonus terms, conducting rigorous monitoring for unusual sign-up and cash-out patterns and performing thorough Know Your Customer (KYC) checks to prevent bonus abuse better but also to maintain the industry’s integrity and trust of genuine players.

Seven Types of Bonus Offers Fraudsters Target

Bonuses are a standard tool to attract and retain players, and each type carries its own abuse pattern.

1. Sign-Up Bonuses: offered to new players on account creation. Fraudsters open numerous fake accounts to claim the bonus repeatedly, a practice known as bonus hunting.
2. No-Deposit Bonuses: claimable without any deposit, which makes them a magnet for abuse. Individuals create multiple accounts to claim them with no intention of legitimate play.
3. Deposit Match Bonuses: the operator matches a player’s deposit up to a set percentage. Fraudsters use stolen card details to fund deposits and claim the matched funds, exposing the operator to chargeback fraud.
4. Free Spin Bonuses: a set number of free spins on slot games. Abusers exploit them through multiple accounts or bots that maximize winnings without genuine play.
5. Refer-a-Friend Bonuses: reward players for bringing in new players. Fraudsters refer fictitious players or use stolen identities to open the referred accounts.
6. Loyalty Bonuses: reward continued play and deposits. Players abuse them with schemes that minimize losses while maximizing rewards, often through coordinated play or multiple accounts.
7. High-Roller Bonuses: target players making large deposits. Abusers can use them to launder money, depositing large sums and withdrawing after minimal play across multiple accounts.

How to Detect and Prevent Bonus Abuse

Bonus abuse costs operators an average of 15% of annual gross revenues, so prevention works best as a system rather than a set of one-off checks. The strongest programs combine identity, device and behavioral signals into a single risk decision at sign-up and cash-out.

• Verify identity at onboarding: Confirm each new player is a real, unique person before releasing a bonus. Document checks, biometrics and proof of liveness raise the effort required to spin up fake accounts.
• Analyze the digital and device trail: Data tied to a user’s email, phone and IP, combined with device signals, exposes the VPNs, proxies and reused devices that link accounts one person controls. This is what makes multi-accounting visible.
• Monitor behavior in real time: Patterns in sign-ups, deposits and withdrawals reveal deviations from genuine play, and velocity rules flag unusual transaction frequency or amounts before a payout clears.
• Apply risk-based friction: Match the depth of Know Your Customer (KYC) checks to the risk of each user, so suspicious sign-ups face extra verification while genuine players pass through untouched.
• Use machine learning to scale: Models trained on historical abuse surface the patterns behind coordinated fraud and sharpen over time as new data arrives.

No single control catches everything, so operators that layer all five close the gaps a standalone check leaves open.

Strategies for Operators to Stay Ahead of Bonus Abuse

Operators must adopt cutting-edge strategies to counteract bonus abuse fraud, ensuring a secure and fair environment for players. Utilizing advanced analytics and machine learning, operators can detect and preempt fraudulent activities by identifying patterns indicative of abuse.

Industry collaboration can further enhance these efforts, creating a robust defense against fraud by sharing insights and best practices. Equally vital is educating players about the risks and signs of bonus abuse, turning them into informed participants who can aid in detecting suspicious activities. Operators can promote a healthy gaming ecosystem by integrating technological solutions, fostering industry cooperation and enhancing player awareness.
