Many casino games have this format, with a representative of the house playing as the banker. These games also work, and are most often played, with one banker and several players. The players have unequal roles: one is the 'banker' and the other the 'player'. The players must play against each other - one against one - and there are no 'partnership' or 'alliance' games. With only two players, there is no possibility of forming teams.
