Common questions

Why does the app say a different play than my chart?
Check the Table tab. The right play depends on the rules: number of decks, whether the dealer hits soft 17, doubling after splits, and surrender. Set them to match the game you play and the drills and charts update.

What does “Apply count deviations” do?
It turns on card-counting mode. Each hand comes with a Hi-Lo true count, and you are graded on the index play for that count (the Illustrious 18 and the Fab 4) instead of plain basic strategy.

How do I reset my stats?
Open the Stats tab and use the reset button at the bottom.

Does it need internet?
No. Everything works offline, and nothing you do leaves your phone. See the privacy policy.
