This is an improved game with added game elements. The interest rate is variable between 1% to 10% depending on balance growth so timing of withdrawals are more important than other similar games. There is no commission or referrals. 100% goes back to the players. For fairness on high interest days, a maximum of 10% of total deposit can be accrued in interest (eg. one full day's worth at 10% interest) for each withdrawal so make sure to withdraw before that point so as not to lose the difference.
