Often any cash winnings from free spins may have to be played through before they turn into withdrawable cash. Check the terms and conditions to make sure you understand how these winnings are treated.You should also be sure that the free spins are genuinely free. In many cases, a deposit of real cash will need to be applied to a newly registered account for the free spins to be awarded. Therefore, often, free spins are not free per se.
A turnover requirement means you have to wager a multiplied amount of the bonus offered.
These can range from 10 to even more than 100 times. Usually, you will find the higher the bonus offered, the higher the multiplier will be.
Again, there may be another clause that even if you manage to make a profit after completing the wagering requirement, there will be a limit to how much you can win from bonus funds.
An example would be something like a maximum £500. So if you were to finish your turnover requirement and have £700 balance won from bonus funds, you would only be able to take £500 as cash.
What happens to the extra £200 is again depending on terms; in some cases, they will be wiped off; if you are fortunate they may be converted to more bonus funds.
This is a fundamental process in any form of gambling. You should have an overarching figure that you are prepared to lose.
Do not go beyond that figure and empty your bank chasing losses.
How long you stop for is up to you, but once you are ahead the only way you can lose is if you take the decision to carry on gambling
The online slots that payout the most could be those with the highest return to player percentages, but they could also be those that are included in huge progressive jackpots. So, for day to day play, high RTP slots are recommended, but if you are looking for a huge Jackpot, go for the progressives.
