HiLo count is maxed out at 10 on hand analyzer but it’s very common to have counts up to 20 towards the end of the shoe and it would be great if this can be adjusted. Also, the session simulator could use a bet spread as people rarely flat bet ### 5/5 — Great app!! *2018-10-29* Unique way to learn and improvised your game skills 😎 ### 5/5 — Great training tool *2018-10-28* Perfect tool to practice every iteration that you might encounter at a casino. Makes practicing far more fun than reading a standard cheat sheet and has a tool to understand more complex scenarios. Important investment to look smarter than your friends next time you visit Vegas. ### 5/5 — Great Blackjack aid; Basic strategy and much more *2018-10-28* I wish I had had this app when I first visited Vegas in the 90s. Back then you could buy a Basic Strategy wallet card from a gas station and do pretty well as the 21 tables. But this is on a whole new level. It has flash-card like capabilities and lets you tune the rules to match the variant you’ll play at the casino. What’s extra cool is the odds calculation. It does it in real time apparently using a Monte Carlo simulation. This shows your or the house’s edge and verifies adages like “never take insurance” (almost never) and other advice (spilt aces, never split 10s, etc.). Next time I go to the casino I’ll be sure to bone-up with this app beforehand. ### 5/5 — Love flash card mode! *2018-10-28* I like how I can quickly blast through flash cards, practicing what I know and learning along the way. It is smart about how it trains as well, repeating what I don't know. Great training app! ### 5/5 — Nice! *2018-10-28* This is the best app I found that is actually serious about training you to lay blackjack in real life circumstances. You can check the math on all possible situations in detail and go into why a given play is optimal. Highly recommended! ### 5/5 — Very Helpful! *2018-10-28* Maybe I will finally be able to beat my brother! ### 5/5 — The math and science behind blackjack *2018-10-27* Playing Blackjack in the casinos is one my favorite games. So often I see people making the wrong call based on probabilities, giving the house even more advantage than they should get. This app rights that to a degree and precision I have never seen before. Instantly turning you into the best blackjack player the Bellagio has ever seen. This app is not even the price of a buy-in and could easily save you money buy helping you learn, understand, and make the right call based on science and math. ### 5/5 — Fantastic app!! *2018-10-26* Awesome app, very clean and easy to use! 👍🏻 ### 5/5 — Best blackjack odds calculator out there *2018-10-26* Must download for anyone who plays blackjack! ## Frequently asked questions about Blackjack Shark ### What is Blackjack Shark?
