Puzzle has been released in version V2.0.3.
Puzzle is a free, ad-free and offline collection of more than 300 brain training games built with Flutter, bundling logic, math, word and memory challenges in a single minimalist app.
This update follows shortly after version 2.0.2. Phones can now request the removal of the titlebar, a contribution from SimonSchubert - the project’s first external contributor.
