Terms and Conditions for Welcome Bonuses for Slots

Furthermore, finding the most favourable terms and lowest wagering requirements will increase your chance of making a cash out.
Wagering requirements vary, where one site will offer a welcome bonus of 100% up to £100 with a wagering requirement of 35x the bonus funds (35x£100 and a total of £3500 wager). Another casino may set the wagering requirement as 30x the deposit and bonus.

What are wagering terms and conditions for welcome bonuses for slots
Wagering terms can also vary between casinos and we suggest these are read and understood before signing up and making your deposit.
Make yourself familiar with these bonus terms and some of the most important rules applied to the bonus funds. There will be minimum and maximum bet sizes you can play. As an example, one casino site may set the maximum bet for each spin at £5, where another casino may set the maximum to £2.
These terms should be understood and taken into account when signing up and claiming welcome bonuses for slots, as breaking these terms can result in forfeiting the promotional funds and any wins associated with it.
Restricted games when using bonus funds
Some games maybe prohibited from playing whilst bonus funds are active. These games will be stated in the bonus terms and conditions.
The games which are typically restricted from promotions include; progressive feature slots, very high RTP games and occasionally jackpot slots.
What are progressive feature slots?
A progressive feature slot will include a free games or jackpot feature round which can be triggered after a certain amount of spins. This can also be awarded for collecting a specific symbol on the reels each spin.
Why are progressive slots restricted from welcome bonuses for slots
These slots are restricted due to avoid bonus abuse, where players can use bonus funds to fill the meter or progressive jackpot with their bonus funds, only to return later to collect the feature with a cash balance. Casinos will add restricted games under their bonus terms for welcome bonuses for slots.
Why are high RTP games restricted from bonus funds?
Due to the wagering requirement added to bonus funds, some high RTP games may not be included in the available slots to play with your bonus, this is to avoid bonus abuse.
Slots with high RTP could be played over a long period just to convert the bonus balance to cash, this is why you will find some slots are restricted when you have an active welcome bonus.
Always check if there are games which you are restricted from playing when claiming welcome bonuses for slots as this could break the bonus terms and conditions.
