Yes, you can. But no deposit bonuses will not give you anything but excitement from winnings (if there are any). Besides, there are many restrictions on available games, betting amounts, and other things when you play with a bonus. So if you want to use a bonus, use it. And if you want to practice casino games, it is better to play for free or with your own money.
Often, online casinos state in the terms of a refer-a-friend bonus that you are eligible for the bonus only after playing at the online casino for real money. In other words, you need to deposit at least once to get the link and associated rewards. However, this rule may vary for some online casinos. So, always check the bonus terms beforehand.
There are many slots tournaments on online casinos. Choose the one that you like best. Maybe you want to win a lot of money, then you need to look for tourneys with the biggest prize pools. But if you want to have fun, you can enjoy any free slot tournaments.
First of all, you should check with your no verification casino what payment methods it offers. Then, pick an e-wallet that you see on the site. Make sure its service suits your preferences (check out the fees, transaction limits, and so on). Aside from e-wallets, you can use a crypto-wallet as a payment method at a no verification casino. If you hold any cryptocurrency, especially bitcoin, it won’t be a problem to find an online casino that accepts cryptos and easy withdrawals.
As long as you want. In fact, online casino games are eternal, meaning they have no time limit for both real money and free mode. Basically, you can play until you run out of credits. When your free credits are over, you can just refresh the page and enjoy the free game again.
Low hit frequency means that you will win less frequently, but the payout will be big. But at the same time, it means that most times you will have losing spins more than winning ones. This is why you should not consider that low hit frequency slots will help you make bigger winnings.
