In-App Purchases
Cash packs, spins, chests, ore crates, scans and boosts in GrandRich Master are purchased through the Apple App Store or Google Play. If an item does not appear after payment, force-quit and reopen the App, then contact us with the approximate purchase time and product name.
Chest drop odds
Every chest sold in the Shop has an ⓘ button on its card. Tap it before buying to see the chance of each card rarity, the guaranteed rarity of the last card, and the bonus items included. The odds already include your pet's current luck.
Refunds
Apple processes App Store payments. Request refunds through Apple (reportaproblem.apple.com). For Google Play, use your Play order history. You may copy us on the request so we can check whether the item was delivered in GrandRich Master.
Saved progress
GrandRich Master has no accounts and stores progress only on your device. Uninstalling the App or clearing app data removes your save and it cannot be restored by us. To start over on purpose, use Reset game in your Profile.
Fortune machine
Spins refill for free over time, and extra spins are sold in the Shop. The machine pays in-game currency only. GrandRich Master does not offer real money gambling or any way to win real money or prizes.
