Verdict
The clearest difference is review sentiment: Slitherlink at 89% against Hitori's 27%. Slitherlink also leads on rating (4.8 vs 3.8) and ratings volume (461 vs 44). Hitori's advantage is update cadence (monthly vs every 4 months) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Slitherlink sells 13 one-off in-app purchases and Hitori sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Slitherlink holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Slitherlink has 461 ratings behind it against 44, so its average is the more settled of the two.

Slitherlink ships an update every 4 months, Hitori monthly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
