They reveal that 49% of you choose free spins no deposit as your favourite, followed by first deposit bonuses and, later down the line, no wagering bonuses.
All the data in this study was verified by Ionut Catalin Marin, founder of KingCasinoBonus and CEO of parent company Dopamine Gaming.

Free Bonuses Lead Industry Engagement
Free spins with no deposit are still dominating your preferences. Nearly half, more precisely 49%, of all bonus claims. This is a 7% increase from 12 months ago until now.
This showcases your familiarity and ease of use, since these bonuses do not require payments from you. Our data shows that 73% of those who claim free spins no deposit bonuses return to make a real money deposit within 30 days.
The most popular games for free spins remain classic slots like Book of Dead, Starburst, and Big Bass Bonanza, with these three titles accounting for 68% of all free spin redemptions. Interestingly, newer slot releases are gaining traction, with games launched in 2024 representing 15% of free spin usage.
Welcome Bonuses Grow in Popularity
Welcome bonuses, packages or first deposits are in the second most claimed category, as 27% of you use them.
The higher maximum cashout limits and a larger list of playable games are identified as the main reasons for your online casino bonus choice. These bonuses typically offer match percentages ranging from 100% to 200%, with the sweet spot being 150% match bonuses, which account for 34% of all welcome bonus claims.
What’s noteworthy is the evolution of welcome bonus structures across the years. Multi-tiered welcome packages spanning your first 3 to 5 deposits have become increasingly popular, with 62% preferring these extended offers over single-deposit bonuses. The average welcome package now extends across 3.2 deposits, compared to 2.1 deposits in 2023.
No Wagering Remain a Constant Preference
24% of you claim a no wagering bonus, a constant value as in the previous years.
Despite their rarity and sometimes stricter limits, they are still among your favourites, since they give you instant access to the cashout process, once your play is complete. The stability of this percentage masks an interesting trend: while the overall claim rate remains constant, the average value of no wagering bonuses has increased by 23% year-over-year.
Mobile Gambling Impact on Bonus Claims
More than 80% of all your gambling sessions are played and completed on smartphone devices. Out of these, 41% are using mobile exclusive bonuses, a trend 8% higher than in previous years (2023 and 2024).
iOS users are 12% more active when gambling as opposed to Android users. This disparity extends beyond simple usage patterns, as iOS users also demonstrate 19% higher average session values and 26% longer session durations.
Mobile bonus redemption patterns also show distinct behavioural differences from desktop users. You’re 43% more likely to claim bonuses during commuting hours (7-9 AM and 5-7 PM) and 67% more likely to engage with push notification-triggered promotions. Moreover, weekend mobile bonus activity peaks on Saturday evenings, with Friday showing the highest conversion rates from bonus claims to real money play.
Industry Experts’ Perspective on Bonus Gambling Preferences
“While it is no surprise that free spins no deposit bonuses are still the most popular, the newest data confirms that players are drawn to slot-based games and prefer choices that do not affect their gaming budget.”, comments Alexandra Camelia Dedu, casino bonus expert at KingCasinoBonus.
“Casino operators are taking note of player preferences and are constantly refining their slot games and bonus catalogues, while not ignoring the payment-based casino offers”, Antonia Catana, senior casino author at KingCasinoBonus, states.
“We’ve constantly updated our bonus portfolio and hands-on testing to reflect the needs of online gamblers around the world. 2025 is the year that requires simplicity and transparency from bonus auditors and casino operators alike”, concludes Ionut Catalin Marin, founder of KingCasinoBonus.
