Junk Stack — Support

Pick bottles, cans and boxes out of the pile and stack them past the goal line before the clock runs out. When the tower falls it does not end the run — the debris becomes your new floor. Only the clock can beat you.

Frequently asked questions

My tower collapsed. Did I lose?

No. A collapse is never a failure in Junk Stack — the pieces stay on the field and you keep building on top of the wreckage. The only way to lose a level is to run out of time.

How do the stars work?

★1 for clearing the level. ★2 if you finish with at least a quarter of the time left. ★3 if you meet the ★2 time and finish half a metre above the goal. Stars unlock the later worlds.

A world is locked.

Each world opens at a star total, shown on its card as how many stars you still need. Replaying earlier levels for a better star rating counts.

The piece won't rotate.

Drag the wheel at the bottom right while you are holding a piece. Rotation snaps in small steps so the same placement can be repeated.

I bought Remove Ads but still see ads.

Open Settings → Restore Purchases. If that doesn't do it, check you're signed in with the Apple ID you bought it with. Note that rewarded ads stay available on purpose — they are optional and you only see one if you tap it.

Where did my Time Pack boosters go?

Boosters never expire. They are stored on the device, so they don't move with you to a new iPhone. If a purchase went through and no boosters appeared, email us with the date and we'll sort it out.

My progress disappeared.

Progress is stored on the device only, so deleting the app or moving to a new phone clears it. Purchases can be restored; level progress cannot.

How do I report an inappropriate ad?

Use Settings → Report an ad inside the game. It opens an email with the app version filled in, which helps us trace the ad with Google.
