Solution? Play and win another game of any type (I played Beginner on Classic mode) and the achievement will pop.
This seems to just be a common problem to begin with. I did the entire thing legit and still had no achievement unlock for me (legit took 120 tries). I played one more on easy and the achievement unlocked thankfully. You should update the guide with this as well as making the achievement difficulty higher than a 2. This game's speed mode and luck based system makes it a bit higher in my opinion. I have more confidence to beat most games on hard mode than to beat that speed level ever again. Also I think once you "dashboard" the timer will not add time anymore. This is what some other threads are talking about. I was wondering why I was losing so bad. Once I stopped using that trick I got it normally.
