# 21 Pro vs Blackjack 21!

The most recent releases landed on October 23, 2026 and October 26, 2026 respectively. ## The numbers | Metric | 21 Pro | Blackjack 21! | | --- | --- | --- | | Price | Free | Free | | Rating | **[4.7 (676 ratings)](https://appshunter.io/ios/app/21-pro-blackjack-multi-hand/id289075847/reviews)** | [4.6 (6.1K ratings)](https://appshunter.io/ios/app/blackjack-21/id1001387844/reviews) | | Number of ratings | 676 | **6.1K** | | Positive reviews | **71.9% of reviews** | 71.7% of reviews | | In-app purchases | Yes | Yes | | Ads | **No** | Yes | | Update frequency | **Every 2 weeks** | Every 3 months | | Monetization | Free with in-app purchases | Free with in-app purchases | | Size | 85 MB | 209 MB | | Requires iOS | **9.0** | 15.0 | | Devices | iPhone, iPad, iPod | iPhone, iPad, iPod | | Age rating | 17+ | 17+ | | Developer | [Avalinx LLC](https://appshunter.io/developer/288162168) | [Do More Mobile, LLC.](https://appshunter.io/developer/318729104) | ## What reviewers say ### 21 Pro [App page](https://appshunter.io/ios/app/21-pro-blackjack-multi-hand/id289075847) Experience the thrill of Blackjack 21 on your mobile device.
