Conversion from Captivate to Storyline 360

I wonder whether there's any mileage in having a question bank linked to each of the tiles (8 question banks). You could put whatever you want on to the slides, no need to have a question, but simply use the random draw to serve up a different slide each time. 

It's certainly possible to do it without JavaScript using Storyline triggers too, but it's quite a complex piece to build. The general jist would be:

• Create a scene for each tile/category and add relevant slides to each scene
• Click a tile on the main screen that generates a random number 
• Depending on the random number generated, jump to slide XYZ. For example, click tile 1 > random number generated = 1 > jump to scene 1, slide 1

Hopefully this gives some idea of how to solve the problem.
