Tri Towers Solitaire

Okay, so here's the deal - you've got a bunch of cards and some towers hidden away. Your mission, should you choose to accept it, is to get rid of all those cards and reveal the towers. How do you do that, you ask? Simple! Just click on any cards that are 1 higher or 1 lower in value than the one at the bottom. And if you need a new card to work with, just click on that closed stack and bam, you've got a fresh one! Easy peasy, right? Let me know if you need any other tips to tackle this challenge.
