Pull the Pins is a pin-removal puzzle with a rescue framing: each level holds a boy apart from his brother, and pulling the pins in the right sequence is what gets them back together.
Everything is visible before you start, so it's pure logic — trace what each pin is holding and what will happen when it's gone, because a wrong order fails the level immediately.
Each pin holds something back, and removing it releases whatever it was holding. The puzzle is the sequence — the same pins in a different order produce completely different results.
Yes — a gentle logic puzzle with a rescue theme and no violence.
Yes — tap the pins. Nothing to install.
