Verdict
The clearest difference is ads: Takuzu at none against Puzzle IO's shown. Takuzu also leads on rating (5.0 vs 4.6) and iOS requirement (9.0 vs 13.0). Puzzle IO's advantage is update cadence (every 3 weeks vs every 31 months) and ratings volume (362 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Takuzu sells 4 one-off in-app purchases and Puzzle IO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Takuzu 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 complicate that: 56% of Takuzu's written reviews are positive against 74% of Puzzle IO's, so the app with the better star average is not the one people write more warmly about.
Takuzu ships an update every 31 months, Puzzle IO every 3 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
