Support
Mini Circuits is made by one person. Email goes to that person, and you will get a real reply — bug reports, ideas, or a board you are proud of are all welcome.
If you are reporting a problem, the three things that help most are: your device (for example iPhone 15 Pro or iPad Air), the voltage tier you were on, and a screenshot. If a run ended in a way that felt wrong, the week number is gold.
Playing
- How do I wire something?
- Drag across the board to lay a trace. Each segment costs 1 from your trace budget. Switch to erase and remove it and the budget refunds in full — changing your mind is always free.
- Why isn't my component lighting up?
- Power only flows between parts of the same colour. A source feeds the consumers on its own net, so check that the trace actually reaches a matching-colour source. The strongest habit is one shared bus per colour: every source on that net then pools to feed everything on it.
- What is the ring of pips around a part?
- That is its pending demand. LEDs sip; heating coils want roughly five times as much. If the ring fills and the part still has not been fed, it overloads and the run ends.
- My board went red and I lost.
- Two different colours ended up on the same line — a short. You have twelve seconds to clear it. Erase back to separate the nets, or drop a bridge so the two lines cross without touching.
- What is a bridge for?
- Two jobs: letting two lines cross each other cleanly, and routing a trace through a component instead of around it. They are limited, so spend them where the board is tightest.
- Can I try it before buying anything?
- Yes — and without the App Store at all. There is a playable board on the home page running the same simulation as the app.
Purchases
- What is free, and what costs money?
- The 12V bench is free, and it is the real game rather than a trial. A single one-time Full Unlock opens 48V and 400V together, plus every future mode. There is no subscription, no currency, no ads, and nothing that can be bought to make a run easier.
- I bought the Full Unlock and it's gone.
- Open Settings → Restore Purchases in the app. Purchases are tied to your Apple Account, so a reinstall or a new device restores them as long as you are signed in with the same account. If the restore message says anything other than that your purchases were restored, email us the exact wording and we will sort it out.
- Can I get a refund?
- Refunds are handled by Apple, not by us — we never see your payment details. Request one at reportaproblem.apple.com. Do tell us what went wrong as well, so it can be fixed.
Syncing and Game Center
- Do my best runs follow me between devices?
- Yes. With iCloud enabled, best scores and settings sync between your iPhone and iPad on the same Apple Account. The sync is through your own private iCloud storage — we have no access to it.
- My score didn't reach the leaderboard.
- Check that you are signed in to Game Center in iOS Settings, and that Mini Circuits is allowed to use it. Scores submitted while signed out are kept locally and are not backfilled to Apple's leaderboards later.
- Can I play without Game Center?
- Yes. Leaderboards and achievements are optional; the game plays exactly the same with Game Center turned off.
Accessibility
- I'm colour-blind. Is the game playable?
- It is designed so nothing depends on colour alone. Two independent toggles live in Settings: Colour-Blind Cues puts a distinct shape badge on every component, so net identity is carried by shape as well as hue; CVD-Safe Palette swaps the net colours for a colour-blind-friendly set. Use either, or both. Nets also carry their own trace dash patterns.
- What about VoiceOver, text size and motion?
- VoiceOver is supported during a run, the interface honours Dynamic Type, and Reduce Motion is respected — including on this website.
