Responsible Design Patterns for Gambling-Related Calculator Tools
Developers build calculators for all kinds of regulated or risky domains: loans, crypto, insurance, betting. The code is usually the easy part. The harder question is what the tool encourages people to do. A wagering requirement calculator, for example, can be built to help someone see that a bonus is expected to cost them money, or it can be built to make the bonus feel like a puzzle worth…
When developing calculators for gambling-related tools, it's crucial to consider the potential impact on users' decisions and wellbeing. Design patterns can help ensure these tools inform users rather than push them towards specific actions.
First, start by clearly stating the tool's purpose and what it's not for. For example, a wagering requirement calculator should help users understand the real cost of a bonus, not recommend offers or suggest strategies to clear requirements quickly.
Prioritize showing the required turnover and expected cost upfront. Avoid emphasizing the bonus amount, which can create an unrealistic impression. Use larger font sizes for the most impactful numbers - the required turnover and expected cost.
Avoid dark patterns in inputs, such as defaulting the wagering base to the bonus only or using high default RTP values. Be transparent about defaults and allow users to make explicit choices.
Make time visible by converting requirements into number of bets and bets per day. This makes the intensity of the requirement more tangible and encourages reflection on whether this level of play aligns with the user's limits.
Acknowledge the average outcome is not always representative by informing users that results are based on averages and many will not achieve the expected outcome. If available, show a distribution or simulation of potential outcomes.
Ensure age gating is clear and prominent. The tool should be restricted to adults and the age requirement should be stated prominently without playful styling. Avoid using game-like features that could encourage habit-forming behavior.
Always make responsible gambling resources visible, such as deposit limit options, self-exclusion information, and support contacts. This information should be easily accessible on every result screen, not buried in the footer.
Avoid placing promotional elements next to the calculator results. The tool should remain a neutral, informative resource, separate from any commercial content or operator promotions.
Lastly, use neutral, precise language. Avoid terminology that implies gambling is a way to make money or that simplifies the risks involved. Provide a glossary of terms to help users understand the offer's conditions. Finally, protect user privacy by not requiring personal data or tracking inputs with identifiers.
