Known Issues

Current version

The latest version of Zoombinis for Mac OS X is 1.0.2. Please make sure you’re running the latest version.

M1 Macs

We have not yet tested Zoombinis on Macs with Apple’s new M1 processor and cannot guarantee compatibility.

Not being able to move past a section or select a Zoombini.

Please try changing the graphics quality to a different (usually “faster”) setting. This has been noticed most frequently in OS X 10.10 (Yosemite).

Fleens – all the Fleens are off the branch but the Zoombinis can’t advance.

Please try changing the graphics quality. This is most commonly seen on “Beautiful” – please change to “Good.”

Some puzzles are unsolvable in a way that all Zoombinis can’t get through.

Some puzzles can just be really hard, but if you think you’ve spotted an issue in the logic, please email us at and include as much detail as possible including your device info and screenshots if possible.

Fleens Tree


The sounds were in our pre-release builds but we ran into technical issues and in scenes where multiple Zoombinis were moving it resulted in a cacophony. We still hope to bring them back someday.

We would like to do more Zoombinis games, but have no active plans to do so at this time.
