Moola

Moola.com is a safe website where you can play games to make money. It is not a scam; however, it requires a huge amount of luck to make a lot of money off of it.

How it works:
Moola is a game site where each new member is given $0.01, and you play games. You are put up against another player on moola. If you win the game, you double your money. If you lose the game, you go back to $0.01. That means that if you win 30 times in a row, you get over $10,000,000 ($10,737,418.24 to be exact). You can cash out when you reach the $10 minimum balance. This seems great, but it really is not as good as it seems. First of all, the odds of winning 30 times in a row are less than 1 in 1,000,000,000. Also, you have to win 7 times in a row (the odds of that are 1 in 128) just to get above $1.

How moola makes money:
Moola is advertising supported. You have to watch a video advertisement before every game that you play. You can skip advertisements, but you have to pay moola every time you skip an advertisement. So, moola basically makes money by paying you to watch advertisements. They must make quite a bit of money off of this because technically they only have to pay about $0.005 for every advertisement watched. How I figured this out: two people watch an ad to play a game against each other. The winner takes all of the loser's money. Moola pays the loser a penny to play again. Therefore, moola only has to pay about $0.005 for each ad watched, while they make far more than $0.005 per ad watched from their advertisers.

Moola's Referral System:
Moola has a multi-tier referral program. You get 4% of what your referrals earn. You then get 3% of what their referrals earn and so on until the fourth level.
