# Sudoku Challenges vs FlipSight

The clearest difference is in-app purchases: FlipSight at none against Sudoku Challenges's 1. FlipSight also leads on ads (none vs shown) and rating (5.0 vs 4.6). Sudoku Challenges's advantage is ratings volume (18 vs 1) and update cadence (daily vs every 3 days). On price, review sentiment, monetization model and device support there is nothing between them.

Both are free to download. Sudoku Challenges sells 1 one-off in-app purchase. FlipSight asks for nothing beyond the download.

FlipSight holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Sudoku Challenges has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
