The digital version of the wooden number tiles. Make various numbers and calculations by dragging numbers and processing possibilities to the designated squares.
Press the cursor button in the toolbar to control the tool. Drag the number cards to one of the boxes with a dotted line. Once a number card is placed in one of the fields you can pick it up and move it to another field. You can also place number cards on top of each other.
The number card will be deleted if you drop it outside of the field.
Click on 'Reset' to clear all the squares with dotted lines.
