# Einstein Sudoku vs Bloom Sort

The clearest difference is ads: Einstein Sudoku at none against Bloom Sort's shown. Einstein Sudoku also leads on review sentiment (50% vs 16%). Bloom Sort's advantage is rating (4.5 vs 4.2) and ratings volume (2.8K vs 12). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Einstein Sudoku sells 3 one-off in-app purchases and Bloom Sort sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bloom Sort holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Bloom Sort has 2.8K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 50% of Einstein Sudoku's written reviews are positive against 16% of Bloom Sort's, so the app with the better star average is not the one people write more warmly about.

Einstein Sudoku ships an update every 5 days, Bloom Sort every 4 days. The most recent releases landed on October 18, 2026 and October 22, 2026 respectively.
