If you want to calculate your potential payout in the long term, you need to know the RTP. You can easily find it in the game rules. Just open the game and head to the rules. Or you can also find a game review and read the RTP percentage there.
Of course, you can. Online casinos let their player try the game for free, first. So, feel free to open a slot in the demo version. You will have free credits to bet on each spin. Practice the game, look at how much you can potentially win, and decide for yourself.
Mirax casino offers players up to 5 BTC. This bonus has no cap on winnings and withdrawals. It means that no matter how much you win, you can cash it all out. However, the winnings from 150 free spins that come on top of 5 BTC let you cash out no more than 0.005 BTC from each set. A set of free spins includes 50 spins.
If you don’t want to receive your free bonus, you can easily cancel it. Contact the customer support manager via live chat and ask them to forfeit your bonus. Or you can just ignore the bonus till it expires itself.
Online slots with the nudge feature are available at nearly all casinos. Even Microgaming-only casinos offer games with the nudge feature. But if you join a site partnered with multiple developers, you will have more options with the nudge feature.
Usually, online casinos mention what slots qualify for the races. Some casinos can allow you to play any slots, while others select one slot and give you points for playing only that slot. So, pay attention to what they say in the terms and conditions of the slot races.
