Hi @Garlic. This is a good start. One way to make the logic puzzle more challenging is to make it so the balls have to be dropped in a specific order to complete the path. I made a demo card below that shows a few ways to do that. In both cases if you hit the wrong ball first it will make it so B can't get to the win block. Spoiler: Ball Logic Demo
Totally agree with @MekaSage ... this was too straightforward but hey,is a start,sure you can do more challenging balls-pushing levels thanks for sharing @Garlic
