In our case, there were 3 people (my daughter, my husband and I). My husband has several flash wallets on his phone, he decided to use coinos for his game character and WoS for the Bank. It was funny when the bank (himself) had to pay him, he would jump from one app to another to make the transactions. My daughter and I were careful that he didn't commit acts of corruption by being the bank and the player at the same time.
