Frequently asked questions
Is my progress backed up?
Progress is stored only on your device. Deleting the app erases your progress, so keep the app installed if you want to preserve it.
Do I need an account or internet connection?
No. Logic Gates works entirely offline and never asks you to sign in.
How do I connect gates?
Two ways: tap a source port and then a destination port, or drag from a source port and drop on a destination. Tapping a wired destination port unplugs that wire.
How do I turn sound off or adjust volume?
Open Settings from the gear icon on the home screen, or from the "More" menu in the workspace. Music and effects have separate volume sliders.
How do I earn three stars?
Complete the puzzle, meet its mastery objective, and solve it without using the tier-3 hint (the one that reveals part of the structure).
