Spot the difference

Your audience can compare two images and spot the differences between them. Upload an original and a compare image, then place hotspots on the differences. When your audience taps correctly, the hotspot is revealed.
Setup
- Click on ADD A BLOCK and select Spot the difference.

- Insert a question into the Title field.

- Insert an image into the Original image box.

- Insert an image into the Compare image box. A circular hotspot will appear which you can click and drag to the right place in one of the images for a correct answer. The corresponding hotspot in the other picture will move with it automatically.

- Click on Add a hotspot and repeat the process for as many points on the picture as you like. To delete a hotspot, click on the three dots next to the hotspot and then DELETE.

- Change the hotspot from a circle to a rectangle by selecting Rectangle from the dropdown menu under the image.

- Insert explanations into the Answer explanations field(s) (optional).
