Terms of Use
Last updated: September 2026
Educational purpose
Blackjack Master teaches basic strategy and expected values. No real money is wagered, no winnings are paid, and nothing in the app is an invitation to gamble.
Accuracy of the calculations
The practice shoe uses six decks. The expected-value model uses infinite-deck probabilities with the rule settings selected in the app; it does not perform card counting. Under different casino rules the optimal play may differ. Figures are provided for study and without warranty.
Age requirement
The app is intended for users aged 18 or older, in line with the age restrictions that apply to gambling-themed content.
Responsible play
Even perfect basic strategy leaves the house with a small mathematical edge. Blackjack cannot be beaten in the long run through strategy alone, and the app makes no promise of profit.
Availability and changes
The app is provided free of charge and may be updated, changed, or withdrawn at any time. Continued use after an update means you accept the revised terms.
