Verdict
The clearest difference is review sentiment: Slitherlink Mastery at 80% against HexaDoku's 23%. HexaDoku's advantage is in-app purchases (none vs 1) and rating (4.8 vs 4.4). On price, update cadence, ads 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. Slitherlink Mastery sells 1 one-off in-app purchase. HexaDoku asks for nothing beyond the download.
HexaDoku holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: HexaDoku has 373 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 80% of Slitherlink Mastery's written reviews are positive against 23% of HexaDoku's, so the app with the better star average is not the one people write more warmly about.
Slitherlink Mastery ships an update weekly, HexaDoku every 5 days. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
