# Senkai Puzzle vs ONO

The clearest difference is rating: ONO at 5.0 against Senkai Puzzle's 3.0. ONO also leads on update cadence (every 2 months vs every 14 months) and ratings volume (9 vs 1). Senkai Puzzle's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. ONO sells 1 one-off in-app purchase. Senkai Puzzle asks for nothing beyond the download.

ONO holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: ONO has 9 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.

Senkai Puzzle ships an update every 14 months, ONO every 2 months. Both last shipped on October 14, 2026.
