Unfortunately, we're not sure exactly what that means. We'd love for it to mean 15 full energy refills, but if you look inside the game, a 30 Energy pot of coffee costs a whopping 30 Adventure Cash. Now, I don't know about you, but that doesn't seem like something Zynga would just give away for free, especially in bulk. This leaves us with another option, the single cup of coffee, which gives you just five energy points. This would be a decent boost, since we're talking about a "free" prize after all, but even then, it still likely won't take you long to burn through all of those bonus energy points.
What's worse, there's yet another option for energy refills: a Bolt that gives you just one energy point. Surely this isn't the "Energy Packs" Zynga is talking about, but it's something to keep in mind all the same. We're working on discovering just which kind of "Energy Pack" you'll receive when redeeming a Zynga Game Card, but for now, why not take a look at our tools upgrade guide, so you'll be able to upgrade your tools to do more work for less energy to make all of your points go that much further.
Will you redeem a Zynga Game Card to earn 15 free Energy Packs? If you have, which specific kind of pack did you receive? Sound off in the comments.
