# Sudoku X4U vs Sudoku Mega Bundle

The clearest difference is ads: Sudoku X4U at none against Sudoku Mega Bundle's shown. Sudoku X4U also leads on review sentiment (86% vs 78%) and iOS requirement (6.1 vs 17.1). Sudoku Mega Bundle's advantage is ratings volume (2.9K vs 32). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Sudoku X4U sells 2 one-off in-app purchases and Sudoku Mega Bundle sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Sudoku X4U against 4.8 for Sudoku Mega Bundle. That said, the two scores are not equally well evidenced: Sudoku Mega Bundle has 2.9K ratings behind it against 32, so its average is the more settled of the two. Written reviews are what separate them: 86% of Sudoku X4U's written reviews are positive against 78% of Sudoku Mega Bundle's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 3, 2026 and October 13, 2026 respectively.
