I'll get right to the point of everyone's question: yes, you do get to actually play the "pull the pin" level from the ads. But they're really just shoe-horned in to your typical resource-management gotcha game. If all you want to do is just sit down and straight solve some puzzles without the usual micro transaction "you've run out of energy/gems/resources, wait on a timer or give us money" nonsense, this isn't the promised land.
