Ever step off a plane and realize you have a pocket full of foreign change?

The Swedish Red Cross and airport operator, Swedavia, have come up with an idea to take care of those spare coins while supporting a good cause — and letting travelers have a little fun while waiting for buses or baggage.

They've turned the vintage arcade games, Ms. Pac-Man, Space Invaders and Galaga, into donation boxes at two airports, Stockholm Arlanda and Göteborg Landvetter. Visitors waiting at baggage claim areas can use their spare quarters and euros to set a new high score. People waiting for a flight can try to top that score while getting rid of unspent krona.

You can use whatever coins you have and every cent, euro, or yen goes straight to the Swedish Red Cross, which had traditional donation boxes in the airports for years.

Red Cross spokesman Morgan Olofsson told Euronews the idea of adding retro arcade games to the mix is "a fun new way to also reward people who make a donation – a win-win, so to speak."

Well, "win-win" until someone beats your high score.
