There are two ways to select multiple cards to place:

1. Tap all the desired cards and then tap the table.

2. Place your finger on the first card and hold down the screen. Drag your finger over the corresponding cards (including joker/wild card) and then directly to the table. If you let go now, all cards should be placed. Make sure you touch the top of the cards when making your selection. In the lower area you can move your hand for better visibility.
