What is the Fifteen Puzzle Application?

What is the Fifteen Puzzle Application?

The Hidden Gems Screencast series was created for developers who are passionate about using Cincom Smalltalk. These screencasts give the viewer live coding examples while sharing valuable insight into the product and informing them about things they may not know.

This month’s new Hidden Gems Screencast demonstrates the design and construction of the Fifteen Puzzle application built in Smalltalk. We use this application as a fun and fast way to learn object-oriented programming and Smalltalk in our new “Quick-Start Guide.”

As an experienced Smalltalker, you may appreciate how clean, simple and small the implementation is for this application. As an experienced Smalltalk developer, you may have colleagues and friends who you wish could learn and experience the power of Smalltalk. Send them here:

If you have questions, comments or ideas for other Smalltalk examples or suggestions for future Hidden Gems, please email the Cincom Smalltalk Product Team at
