You can find reviews and also long lists about gambling platforms in google, I think it depends on what you're looking for...
If you search on google then you will find a lot of sites and there will have a lot of review site of gambling but many of the listed gambling sites might be scam and/or their service might not be the same as on shown on the review site. For example 1xbit is a proven gambling site and they has been listed on the crypto gambling review site with positive review.
