Read full descriptionHide full description
This is a puzzle game where the goal is to make the number of stones (black circles) on the board just one. Each stone can jump over another stone next to it in the vertical and horizontal directions. The stone that is jumped over disappears, reducing the number of stones on the board by one. Keep doing this until there is only one stone left on the board.

Verdict
The clearest difference is price: Mono at Free against SEQ's $1.99. Mono also leads on in-app purchases (none vs 1) and update cadence (every 4 days vs every 6 weeks). SEQ's advantage is ads (none vs shown) and ratings volume (2.6K vs 1). On device support there is nothing between them.

Mono is free to download; SEQ costs $1.99 up front. SEQ sells 1 one-off in-app purchase. Mono asks for nothing beyond the download.
Mono holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SEQ has 2.6K ratings behind it against 1, so its average is the more settled of the two.
SEQ ships an update every 6 weeks, Mono every 4 days. The most recent releases landed on November 10, 2026 and November 4, 2026 respectively.
