Verdict
The clearest difference is ads: Blackjack 21 at none against Blackjack's shown. Blackjack 21 also leads on review sentiment (55% vs 33%). Blackjack's advantage is ratings volume (331K vs 5.7K) and chart position (#17 vs #158). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Blackjack 21 sells 12 in-app purchases, starting at $4.99 per month and Blackjack sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Blackjack 21 against 4.7 for Blackjack. That said, the two scores are not equally well evidenced: Blackjack has 331K ratings behind it against 5.7K, so its average is the more settled of the two. Written reviews are what separate them: 55% of Blackjack 21's written reviews are positive against 33% of Blackjack's.
Blackjack 21 ships an update fortnightly, Blackjack every 3 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
