If you see a purple checkmark next to an item on your game board, it means that this item can be collected to complete a Daily Quest task.

‍

Open the main screen, click the purple chest icon and press the 'Collect' button to complete the related task. This action will remove the purple check-marked item from your game board and send the basket that you won to the bottom (item queue) of your board.
