Some Trustpilot reviews can be disingenuous or fail to reflect a brand’s overall quality, which is why I don’t base our rankings solely on their scores. But the Trustpilot ratings are still useful to gauge how popular and worthwhile an online slot site is. I consider feedback from bettors when putting together my rankings for any article on slot apps and slots sites with Trustpilot scores being a good indicator of a worthwhile brand. I always prioritise responsible gambling in my reviews, which are fair and unbiased. During testing, I found that the best source of free spins at Paddy Power is the rewards club, which offers bettors the chance to claim 25 free spins each and every week. It would be nice to see a few more offers added to the promotions page with the Pinball Prize machine the only option for those seeking to unlock some free spins.
