I've started playing a picture search game called 'Pearls's Peril', where each time you find the list of (somewhat random) item, you get points towards achievements, and sometimes objects that can be used in other parts of the game. There is also a decorate the space aspect (build things, put in gardens), which the coins and objects from the searches are used for.
i know I'm not explaining it very well, but what I'm interested in is whether there are other games that might be a bit like this, that run on ipad? This one has the limitation that you have to have 'energy' to do a search, and this regenerates at one per twenty minutes to a max of ten. Which means that every two and a half hours I can spend between five and ten minutes playing, and then nothing.
I've found one that looked similar, but was awful (so far - haven't made it out of the interminable tutorial): "Letter Mystery".
