How can we help?

Yes. Fully free on Google Play. 500+ handcrafted puzzles across 7 modes, plus Puzzle Editor and all features — no paywall. Ads appear only between campaign levels, never during gameplay. Optional one-time €3.99 Remove Ads purchase removes every ad forever.

Yes, fully. All 500+ puzzles, 7 modes, and the Puzzle Editor work offline. Internet is only needed for: Daily Challenge sync (optional), Google Play Games cloud save (opt-in), and ads loading (if you haven't bought Remove Ads).

Android 8.0 (Oreo) or newer. The game is lightweight (~65 MB) and runs smoothly even on older devices from 2018+.

In the Circuit Trace main campaign, levels unlock as you solve them. In Classic / Diodes / Portals / Arcade modes, all 100 levels are available from the start — no gatekeeping. Expert preview is instantly accessible.

Open the Creator hub from the main menu, tap "Make a Puzzle", choose a grid size (5×5 to 8×8), place colored pairs and optional diodes, then tap CHECK to validate. Once valid, tap SHARE to generate a short code like CT-NHH06-8CMY4-AG2DS. Share that with friends via WhatsApp, Discord, or any messaging app.

Codes start with CT- followed by 6 blocks of 5 characters separated by dashes. Example: CT-NHH06-8CMY4-AG2DS-C5DJ0-00000-00009. The code encodes grid size, pair positions, diode positions and directions, plus a checksum for typo detection. All 100% offline — no server needed.

Open the Creator hub, tap "Play Shared Code", paste or type the code, tap Play. The puzzle loads instantly. No account, no login — just the code is enough.

Yes. Two options: (1) One-time €3.99 Remove Ads purchase — permanent, no subscription. (2) Rewarded ads: optional, player-initiated — unlock Undo or Hint by watching an ad voluntarily. The core game never forces ads during gameplay.

Six languages: English, Nederlands, Deutsch, Français, Español, Português. All UI, hints, tutorials, and menus are fully translated. Language auto-detects from device settings but can be changed in-game.

No. The game plays great fully anonymous. Google Play Games sign-in is optional and only needed if you want: cloud save across devices, achievements tracking, or global leaderboards (Daily / Time Trial / Endless).

Email [email protected] with: your device model, Android version, Circuit Trace version (shown in Settings), and steps to reproduce. Screenshots or screen recordings are super helpful. We read every email.

Planned, not yet dated. We're a solo indie studio shipping on Android first because we have the tooling for it. iOS version is on the roadmap but requires significant setup time. Follow us on TikTok or Instagram for updates.

If you never signed in to Google Play Games, there's no data to delete — everything is local. If you did sign in, go to Settings → Delete Account & Data in-game, or email [email protected]. See our Privacy Policy for details.
