Verdict

The call

The clearest difference is review sentiment: Castle Solitaire at 68% against Solitaire Uni's 25%. Castle Solitaire also leads on ratings volume (201K vs 816) and rating (4.8 vs 4.5). Solitaire Uni's advantage is update cadence (every 10 days vs monthly) and monetization model (ad-supported vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.
