## Most critical reviews (4 lowest-rated)

### 5/5 — Superior Stats

*2023-01-30, version 1.3.1*

This is the only 21 game I know of that accurately measures expected value. EV is the best way to measure your abilities as an advantage player and the only way to accurately compare your skill against other players.

### 5/5 — Great

*2022-12-07, version 1.3*

My uncle made this game. I like it because you can make money

### 5/5 — Ready for Vegas

*2022-12-06, version 1.3*

I am now much better at card counting. I hope that it pays off somehow. Thanks for the lesson bros.

### 5/5 — Cool way to learn advantage play

*2022-11-20, version 1.3*

This app scores you based on basic strategy and hi-lo card counting strategy. The stats it tracks are cool-it actually uses expected value. Super helpful for practicing for the real casinos.
