I usually ignore the loyalty gimmicks but the gamification here is actually quite detailed with the jungle theme. They have a system where you collect masks and unlock achievements while you play. I saw on https://wazamba-ca.com/ that you can earn coins to spend in a shop which adds some value back to your turnover. It is more engaging than just a boring progress bar. Just do not get too obsessed with completing the collections if it makes you bet more than you planned.
