Hmmm.... reading other answers I might have misinterpreted what was required in this challenge. What is it exactly? For example, if num1 = 121 and num2 = 141, would they be triple troubled numbers?

To achieve that, the only change would be in the if statement. Instead of doing x*3 and x*2, it would be ''+x+x+x and ''+x+x respectively:

if (strNum1.indexOf(''+x+x+x) > -1 && strNum2.indexOf(''+x+x) > -1) {
