What is a streak of ten?

The Plants vs. Zombies achievement Better Off Dead requires that you

Get to a streak of 10 in I, Zombie Endless.

What does that mean?

I've searched & searched and can find nothing specific. I watched a couple of Youtube videos, and it was completely unclear as to what created a 'streak'.

I, Zombie Endless is a puzzle mode version of I, Zombie where any sun you have at the end of a level (eating all five brains) carries over to help you in the next level.

To get the achievement, you must clear ten levels in a row, without losing all your sun (and thus not being able to deploy any more zombies).
