It is a game of demon killing that is based on a storybook called "Momotaro" of Japanese old tales. I will erase and disassemble three or more demons of the same color.The time limit is 60 seconds. By exchanging with the next demon, we will arrange three demons. Replace with dragging. If you do not line up even if you exchange demons, you will return to the original position. When the demon is gone, the upper demon falls. At this time, when colors are lined up a chain will occur. The score changes depending on the number of stones disappeared and the chain. There are scores and bonuses depending on the number of demons erased at the same time and the number of chains.
