7ThirtyWorld Puzzle Studio

One offline app. Two classic pencil games. Seventeen 100-puzzle packs.

Puzzle Studio is a complete puzzle magazine in a single file — no installation, no account, no subscription, and it keeps working with the internet off. Buy the app once, then add whichever packs you like. Every pack is 100 puzzles for $6.99 and stays in your library forever.

Free sample puzzles for both games are built into the app, so you can try before you add a single pack.
