Right now I'm up to nearly stage 50 and have caught more than 30 Pokemon and I haven't run into that trouble yet. But I do know what you mean. A lot of free-to-play tablet games make it impossible to progress unless you spend money. Luckily I haven't gotten to that point in Shuffle yet, so for a free game, I've gotten my money's worth out of it and am still enjoying it in short bursts.
