Just click on a red card, keep the left mouse button pressed and drag it over the gap (marked by "...") where it should fit. Then release the left mouse button.

After all gaps are filled, click on "correct?". The color of the cards that have been correctly inserted will be changed to green.

Incorrectly inserted cards remain red and must be moved to the correct gap. As long as a card is red, you can still take it from the gap and put it anywhere.

Double click a card to hear the word in German.

Remix the cards by clicking on "restart".
