Why can’t I download Spyjinx on iOS?

Like Fortnite and other Epic Games titles, Apple has disabled the option to download or re-install Spyjinx on iOS devices. 

The game remains playable for players that already have the app installed on their iOS device

How to get a refund: 

Apple doesn’t allow Epic Games to directly refund players for iOS purchases and instead requires players to ask Apple for a refund. Please follow these instructions to ask Apple for any refunds for your Spyjinx purchases: https://support.apple.com/en-us/HT204084
