# Blackjack Masters vs Double Down

The clearest difference is rating: Double Down at 4.9 against Blackjack Masters's 4.4. Double Down also leads on update cadence (weekly vs every 5 weeks). Blackjack Masters's advantage is ratings volume (301 vs 7) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blackjack Masters sells 8 one-off in-app purchases and Double Down sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Double Down holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Blackjack Masters has 301 ratings behind it against 7, so its average is the more settled of the two.

Blackjack Masters ships an update every 5 weeks, Double Down weekly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
