# Blackjack 21! vs Blackjack Advisor

The clearest difference is ads: Blackjack Advisor at none against Blackjack 21!'s shown. Blackjack Advisor also leads on review sentiment (100% vs 72%) and rating (5.0 vs 4.6). Blackjack 21!'s advantage is ratings volume (6.1K vs 5) and device support (3 vs 1). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Blackjack 21! sells 5 one-off in-app purchases and Blackjack Advisor sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Blackjack Advisor holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Blackjack 21! has 6.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 72% of Blackjack 21!'s written reviews are positive against 100% of Blackjack Advisor's.

Blackjack 21! ships an update every 3 months, Blackjack Advisor every 3 weeks. The most recent releases landed on October 16, 2026 and October 2, 2026 respectively.
