User reviews

Just download

Pretty good so far rated it a 4 so people can see I’m actually learning pretty fast if ur good at math u can def count

Response from developer

Hi Cfrgdwthcstbcsth! Thanks so much for the kind words, we're really glad you're enjoying Blackjack Guru and learning fast. Happy training!

Far from free……

Aside from the basic strategy chart which is free all over the internet, everything cost $6.99 a week after 50 questions just to see the app. Don’t bother downloading unless you like your time wasted.

App wants a review just for downloading it. Most of these “high star reviews” are from people who reviewed it before they found its $6.99 a week.

Response from developer

Hi Dredger17! Thanks for the feedback. The free version includes more than the strategy table: you can start training basic strategy with a limited number of hands, the first card counting lesson is free, and the full simulator is free without limits. Hope this helps 😊
