A little help from the lab

Hints and circuit connections

Use the bulb on the board for a free hint. The wand below Back offers an extra hint through an optional video, or immediately if Remove Ads is active. Connect silver snaps into a complete loop from the battery and back. Use Undo to try another route.

Restore Remove Ads

Open Settings and choose Restore Purchases while signed into the store account used for the original purchase. Restoring ownership does not restore puzzle progress. Apple and Google purchases are tied to their respective stores; the app does not have a player login for transferring ownership between platforms.

A purchase or price is unavailable

Check your internet connection and try loading the price again in the app. Store products must be available for your region and account. If a payment appears on your store receipt but ownership is missing, contact us with the order reference. Do not include payment-card details.

An ad or video will not load

Ads need a network connection and may not always be available. You can continue playing and use free board hints. With a verified Remove Ads purchase, banners and between-level ads are hidden and extra hints do not need a video.

Music, voice and haptics

Open Settings to change background music, circuit sounds, read-aloud hints and haptics. Device settings and silent-mode behavior may also affect playback. Some simulators and tablets do not provide phone-style haptics.

Progress and daily challenges

Stars, preferences and Free Build projects are saved on your device. The Daily Spark is based on your device’s calendar date. Uninstalling or clearing storage can remove local progress. We do not run a cloud-save service that can retrieve it.
