NOTES FROM THE WORKBENCH

A few sparks to get you started.

New to the workshop or back with a new idea? Start here.

01

Follow the heart

A part needs a working connection to the heart to do its job. Before adding more, check that your existing pieces are powered.

02

Change one thing

Use the Comparison Bench to test two builds under the same conditions. One small change can be easier to understand than a complete rebuild.

03

Make room for a surprise

Rotate parts, explore unusual board spaces and try a different Rascal. A shape that seemed awkward might be the missing piece.

04

Keep your favorite idea

Save builds and export a backup from Settings. Purchase restoration and progress recovery are separate, so keep a copy of the progress you care about.

GOOD QUESTIONS

Before you open the toolbox.

Is Rivet Rascals free to play?

Yes. The full 60-mission campaign, all eight Rascals and all 66 functional blueprints are earned through free play. Optional purchases add cosmetics, story access and creative Workshop Club benefits, never combat power.

Can I play offline?

Yes. Local play works offline. Downloading the app, purchases, restoring purchases and optional iCloud features require an internet connection. Some Apple services also require the appropriate Apple Account.

Do I play against other people?

Battles are against authored workshop automata. There is no live matchmaking, public chat or public player feed, so you can tinker at your own pace.

Which devices can I use?

Rivet Rascals is a native game for iPhone and iPad running iOS or iPadOS 17 or later. Check the App Store listing for current device compatibility.

What happens when Workshop Club ends?

After ordinary expiry, legitimate permanent cosmetics and existing saved builds remain. Those builds stay editable and exportable. Creating new builds above the free 12-slot limit and starting membership-only activities require active Club. Refunds or revocations may remove the affected paid entitlement.

Are there accessibility options?

The game offers alternatives to drag placement, reduced decorative motion, readable battle reports and separate sound and haptic controls. Explore Settings to find what works for you.
