It is a game that you boil an egg to collective an ossan (an old man in Japanese). It only has 2 steps to play: boil an egg, pell off the shelf. There are different kinds of salt and eggs which will affect the result. Once you have 12 boiled ossan eggs, you will get a new pot. Each ossan egg has its own character setting, like a stabber office worker or a shy restaurant owner.
I like it because it is simply to play. I don’t need to spend a lot of time on it but it’s still fun. This game is similar to Mushroom Garden App which came out few years ago. Also, it has nice graphic design. I think the only weak point is you have to understand Japanese.
