<li>
For each one of the 9 categories of images, you will be presented with
the 15 possible image choices. The categories are shuffled at every
login. They will not always appear in the same order.
</li>
<li>
At each category, only one of the 15 displayed choices is the correct
image that belongs to your pazzle. Find it and tap or click on that one.
The 15 images are shuffled too, they will not appear at the same
position at each login. On a computer, you can also use the tab key on
your keyboard to move to the desired item on the screen, then press the
space bar to select each one.
</li>
<li>
Once you completed the last category, you will be presented with all the
images you have previously selected. Their order is displayed as it was
when you picked them. But this is not the correct order of the images in
your pazzle. You now have to order them correctly.
</li>
<li>
You must remember which image should be the first one in your pazzle.
Find it on the screen and click or tap on it. It will be greyed out and
the number 1 will appear on top of it.
</li>
<li>
Move on to the second image of your pazzle (that you memorized). Find it
on the screen and tap on it. Repeat this step until you reached the last
image.
</li>
<li>
Finally, your PIN code will be asked. enter it by clicking or tapping on
the digits.
