Abstract
Currently, social games that are easy to do with smartphone are prevalent. Basically they can be played for free, but players need to use “Gacha (Gasha)” when strong characters or cards are needed. In order to use Gacha players need to prepare in-game currency. In-game currencies are sometimes distributed free of charge, but they usually need to be charged. From various investigations, there is no gender difference in the percentage of people who are charging, but it is known that there is a gender difference in the amount of charge. Therefore, the authors thought that there might be some difference between the game for men and the game for women. As a survey method, men's game and women's game were prepared for each of the four genres and compared and verified. As a result, it was found that there is no big difference between the game for men and the game for women, even if there is a gender difference in billing amount.
