Bookmakers With the Best Bonuses
Why Do Bonuses Matter?
Bonuses are an essential part of the online betting experience, adding value for both new and seasoned players. They provide extra funds or free bets that boost your bankroll, giving you the opportunity to explore different markets with less personal risk.
Boosts Your Bankroll
Bonuses give you extra capital—through free bets or bonus funds—that lets you take higher risks without using your own money. This extra boost allows you to try different strategies and enjoy betting with a financial safety net.
Great for Newcomers
For newcomers, bonuses offer an accessible entry point to a bookmaker’s platform. They ease the initial learning curve and help you become familiar with the betting process without a significant upfront investment.
Rewards Loyalty
For regular customers, ongoing promotions provide added value that acknowledges your continued support. These rewards ensure that you feel appreciated and incentivised to stick with a bookmaker over the long term.
Always remember to review the terms and conditions attached to any bonus offer, including wagering requirements and restrictions, to fully benefit from the deal.
Our "Bonuses Rating" Explained
Our Bonuses rating measures the quality of a bookmaker’s leading sports welcome package and the ongoing value offered to existing players. In our evaluation, the welcome package is given extra weight to better assist newcomers.
Part of the score is derived using an “average case” scenario for the welcome package, based on a few key assumptions:
- Representative Odds: We assume the random odds collected at the bookmaker accurately reflect the overall value offered by the site (see Highest Odds Rating for more details).
- Qualifying Bets: Qualifying bets are assumed to be placed at the minimum required odds for the promotion (e.g. 2.0).
- Free Bet Placement: Unless otherwise stated, free bets are assumed to be placed at decimal odds of 3.5, representing “medium-risk” outcomes, often found in popular sports like football and tennis.
These assumptions are applied consistently across all betting site reviews on Punter2Pro, ensuring that free bets and promotions are compared in a fair and standardised manner.
This process highlights valuable promotions while also identifying cases where a typical bettor might not benefit.
