A closer look at the trade-offs
Puzzle depth versus free invention
The finite challenge deck supplies direction. A free-building toy is the better choice when inventing the entire project matters more than reaching a specified target.
Setup, storage & first play
- Keep the cards and marbles together. Use a table where loose pieces can be recovered.
Try this first
