If you’re looking for an addicting iOS game, check out My Singing Monsters. My wife downloaded it a while back and I’ve recently become addicted.
Basically, you get to raise these cute little monsters that make music. Add more monsters and they make beautiful music together.
As you work through the game the monsters earn coins which you then collect to buy scenery or more monster eggs. You can breed them and buy them things that make them happy. Feed them and just enjoy them.
It’s quite a fun little game and it’s free. You can do in-app purchases of course, or you can just play for free and enjoy.
My Singing Monsters is my current iOS game addiction and you should check it out.
Oh, and I think it’s available on Android too.
