Note:This only work on Hero Quests. This works like a charm, however when you turn your WiFi back on and play the game again your gem count will be reset back to what it was before you started doing the cheat. I'd imagine this also applies to sparks as well. I'd imagine you'd have to be online to buy packs (at least the gem ones) and even then I'm pretty sure the game won't allow you to anyway.

It's probably just something you'd do once, comment "Oh, that's neat." and then switch WiFi back on because there's no point in continuing.
