Comparing welcome bonuses

We’ve tested and analyzed all the offers of online casinos. Out of all these promotions, only the most profitable have been selected. We prioritized the first bonus offered, as well as the combined total of the offers made by each casino. By doing this, we are sure to list only the most profitable bonuses on this page. Furthermore, all these offers work on the Mega Moolah slot machine.

Bonus or free spins – Which one to choose?

Wondering whether it’s better to opt for a deposit bonus offer or free spins? Knowing which of these two options is more profitable is important. The difference is in the amount payable on the first deposit. With deposit bonuses you have to deposit more money, while with free spins a few dollars are enough. The deposit bonus offers are a great opportunity to play a much larger number of free spins on the Mega Moolah game.
