# Slitherlink Mastery vs HexaDoku

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.

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.
