It is similar to poker, although it lacks the social dynamics that make it fascinating.
Instead, you have some cards are dealt with passive effects, all aimed at maximizing your score (big numbers = happy brain). It's fun at first, but soon becomes a repetitive cycle. Each game feels like a rehash of the last until you run into a bind boss that turns your strategy upside down and leaves you unable to adapt. There came a point where, if I didn't defeat the first bind on the first hand and no decent card appeared in the store, I would restart the entire run, because otherwise it was a waste of time. That's when I realized that the game wasn't worth playing.
