# Threes! vs Zachtronics Solitaire

The clearest difference is rating: Zachtronics Solitaire at 4.4 against Threes!'s 4.0. Zachtronics Solitaire also leads on update cadence (every 4 days vs every 3 weeks) and price ($4.99 vs $5.99). Threes!'s advantage is ratings volume (3K vs 47). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Threes! costs $5.99 and Zachtronics Solitaire $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Zachtronics Solitaire holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Threes! has 3K ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 79% of Threes!'s written reviews are positive against 77% of Zachtronics Solitaire's, so the app with the better star average is not the one people write more warmly about.

Threes! ships an update every 3 weeks, Zachtronics Solitaire every 4 days. Both last shipped on October 15, 2026.
