How to show respondents as many questions as they can answer for 90s?

Hello,

I am trying to figure out how to code in qualtrics a task such that respondents would have 90 seconds to solve as many matrices as possible. To solve a matrix, they have to count the number of 1s. Once an integer between 0 and 50 is entered, another matrix would appear and so on until the 90 seconds are up. I have been looking and it seems that I cannot implement this without using some javacript (but perhaps I am wrong?). I would be very thankful if someone knows how to do this either with or without having to code using javascript. 

This is what it would look like

Thank you,
