# Fubuki vs Puzzle IO

The clearest difference is in-app purchases: Fubuki at none against Puzzle IO's 1. Fubuki also leads on ads (none vs shown) and rating (5.0 vs 4.6). Puzzle IO's advantage is update cadence (every 3 weeks vs every 52 months) and ratings volume (362 vs 1). On price, review sentiment and device support there is nothing between them.

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

Fubuki holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Puzzle IO has 362 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 75% and 74% positive.

Fubuki ships an update every 52 months, Puzzle IO every 3 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
