# Smart Sudoku vs Memory Game Retro Puzzle

The clearest difference is rating: Smart Sudoku at 5.0 against Memory Game Retro Puzzle's 4.4. Smart Sudoku also leads on iOS requirement (12.0 vs 15.0). Memory Game Retro Puzzle's advantage is review sentiment (100% vs 60%) and monetization model (free vs paid). On price, ads, in-app purchases and device support there is nothing between them.

Smart Sudoku costs $0.99 and Memory Game Retro Puzzle $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Smart Sudoku holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Memory Game Retro Puzzle has 163 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 60% of Smart Sudoku's written reviews are positive against 100% of Memory Game Retro Puzzle's, so the app with the better star average is not the one people write more warmly about.

Smart Sudoku ships an update every 9 months, Memory Game Retro Puzzle every 3 months. Both last shipped on November 10, 2026.
