Drag one rock onto its neighbour to line up three of a kind. They blast, the rocks above fall in, and chains keep going on their own. Then drag Moss's ship into the gap, or tap a glowing square. Reach the glowing opening at the top to clear the quadrant.

For a refresher any time, open Settings and tap How to Play for a short demo board.

Every swap burns fuel. Fly through the gold stardust to fill the tank. If the tank runs dry, that trip stops. Stardust is only found in play and is never for sale.

Rocks and pirates dent the hull. While you're away, time mends the hull and tops up the tank a little every hour, up to 70%. The rest you earn in play, or you can repair the ship with credits at Galactic Trade.

Pirate ships open fire when you sit beside them. Keep moving and steer around them.

Open Settings and tap Story Mode to watch how Moss got here.

Open Settings and set Effects to LOW. Closing other apps can help too. If it keeps happening, email us with your iPhone model.

Yes. Settings, then Sound. It covers the music, effects and the films.

Yes. Everything is built into the app, so you can play without a connection.

No. DustDash is free, and credits can be earned in play by mining crystal and selling salvage. Credit packs are optional.

Make sure you have a connection when you buy, and keep the app open until it says the credits were added. If you were charged and the credits didn't arrive, email us with the date and the pack, or ask Apple for a refund at reportaproblem.apple.com.

DustDash has no account, so your game and credits are saved only on the phone you play on. If you move to a new iPhone by restoring from a backup of your old one, your game usually comes with it. If you set the new phone up fresh, DustDash starts a new run. Credits can't be restored by us, because we never hold a copy.

Use Apple's Screen Time (Content & Privacy Restrictions, iTunes & App Store Purchases) or Ask to Buy in Family Sharing.

App Store purchases are refunded by Apple. Go to reportaproblem.apple.com, sign in, and choose the purchase.

Sorry, we can't. Your game is saved only on your phone and we never hold a copy. Progress is lost if you tap NEW RUN, delete the app, or reset or replace your phone without restoring a backup. If you have an iPhone backup made before it went, restoring that backup may bring your game back.

Open Settings and tap NEW RUN, then TAP AGAIN to confirm. This wipes your run and everything bought, including credits, and starts a fresh game. It can't be undone.

Delete the DustDash app from your iPhone. That removes everything it saved. We don't hold any of your game data, so there's nothing for us to delete. If you've emailed us and want those emails deleted, just ask.

No. There's no account, no ads, no analytics and no tracking, and the app sends nothing about you to us. The privacy policy has the details.
