I used to get lost with the number of casinos too and realized that the most important thing is to read the bonus and withdrawal terms, not just look at the design. A couple of times I got free spins with such a crazy wager that there was no way to win anything, so now I always check the rules before signing up. Once, to double-check the terms, I opened https://no-deposit-bonuses.co.nz/free-spins/ and noticed they explain the restrictions and activation steps really well, which a lot of people skip. After that, I play less often but feel calmer, and I set withdrawal limits in advance.
