I've never been very good at challenges, but BaC really appealed to me, anyone interested in seeing how it goes can look here for updates. Not much there yet, but will update as I go along
While stuck in traffic I was looking for something to pass the time and discovered spinmama through a helpful comment. The interface is easy to navigate. After losing for a while I increased my bet slightly and hit a strong combination that covered everything. The result was pleasing. This has become my go-to casino.
