Crafty Marbles

Marble-run sandbox

Crafty Marbles is a PC sandbox game about building marble runs from tracks, interactive gadgets and logic-driven contraptions. You snap parts together, set up how marbles behave, then watch the machines run and adjust them to see what happens.

Runs can be calm or hazardous. Splitters, teleporters and traps shape the routes, while logic gates can direct marbles according to properties such as color, size or race position. You can make a blue marble go left, enlarge a tiny one or send the last marble into a hammer.
