The Mixer is an optional feature in the Marketplace that lets you trade surplus Original cards for a fresh chance at more useful ones. You can access it in the Marketplace by swiping the top layer downward.
How it works: Choose exactly four Original cards from your collection, tap Mix, and pay €1.99 via Apple/Google Pay. You’ll then receive four new cards as if for a flight (2 City, 1 Airline, 1 Aircraft). From these, pick two to keep; the other two expire.
Rules & pool: Only Original cards are allowed as input; Non-Original (e.g., Welcome, Miles & More, or traded cards) are not accepted. Outputs come exclusively from the regular flight pool. There is a small Joker chance (~1%): if it triggers, a Joker replaces one of the four output cards and can be chosen like any other.
Usage & fairness: You can use the Mixer as often as you like. Randomization runs server-side and is logged; if the app closes during the process, your result will be restored when you reopen. Mix operations are final once confirmed.
