100% Deposit bonus wagering varies from one online slot site to another and free spin winnings are subject to wagering requirements.

300% Deposit Bonus
300% First deposit bonuses are not the norm although the huge percentage does attract the attention of big bonus seekers.

TERMS AND CONDITIONS OF A 200 WELCOMER BONUS
The key to using your 200 Welcome Bonus to its full potential lies in the terms and conditions. The better you understand the T&C part of the bonus, the easier it is to claim huge payouts. One of the big confusions is part of wagering requirements, which is the number of times you need to wager the bonus. More specifically, wagering requirements can be on the bonus amount only or include both the activating first deposit and the amount of the bonus.
The percentage that each game type contributes towards wagering varies, generally, slots contribute 100%, although several high volatility slots are excluded. The titles of the slots not contributing towards wagering are listed in the bonus terms section and almost always include progressive jackpots.
The wagering period differs from one casino to another, at some casinos you have 14 days for example to reach the playthrough requirements and at others 30 days. The longer the wagering period the higher your chance of reaching it before the bonus funds expire.
Wagering requirements also vary in terms of the number of times you need to wager the bonus or the bonus and qualifying deposit. This could range from 30x to 35x up to 40 times and higher, which is why it is important to read the T&C to find out the real bonus value before accepting a bonus.
The minimum deposit to activate the bonus is important, if you deposit an amount lower, you won’t qualify for the deposit bonus. Some casinos require you to use the bonus code to activate your bonus, others offer activation via a pop-up screen. At most United Kingdom casinos the bonus activates automatically via your initial deposit.
Maximum winning caps show the highest amount you will be able to withdraw, regardless of the amount you win. The max winning amount is paid once you’ve completed wagering within the specified period and if your winnings are equal to the maximum or higher.
Best Payment Method to use Claiming a 200 casino Bonus offer
Payment methods contribute hugely to the actual value of claiming the best bonus offers such as the 200 Casino first deposit bonus.

This means PayPal is one of the most preferred payment methods when it comes to claiming the exceptional 200 casino bonus offer.
Paysafecard – The main benefit of Paysafecard is that the prepaid payment service makes it possible to fund your casino account or activate the 200 deposit bonus via cash. Only the voucher number is shared with the casino and funds clear instantly, while Paysafecard is accepted at all the best online casinos. One of the biggest benefits is that the prepaid voucher enables users to keep track of their spending and remain within their entertainment budget.
Trustly – Trustly is one of the most trusted payment methods in the UK and offers safe and secure instant transactions. Perfect to use on mobile devices, Trustly makes it possible to fund casino accounts in multiple currencies and no financial details such as bank account numbers or debit card details need to be shared with the casino.

For example, if the bonus spins are added at 20 per day, the first 20 is available instantly and the remaining 80 at 20 per day across the next four days.
The winnings achieved via a free spins bonus are subject to wagering requirements noted in the bonus terms. The bonus spins winnings are generally added to the bonus funds separate from the cash funds.

200% DEPOSIT BONUS UK – FREQUENTLY ASKED QUESTIONS
HOW MUCH ADDITIONAL FUNDS CAN I CLAIM BY ACCEPTING A 200% DEPOSIT BONUS?
The only way to find out exactly how much you can claim in additional bonus funds by accepting a 200% deposit bonus is to read the bonus terms and conditions. The maximum bonus amount offered by a 200% welcome bonus is normally determent by the amount a new player deposits. For example, an initial deposit of £200 unlocks a 200% match bonus of £400, which means the newly registered member starts playing with a bankroll worth £600.
The terms and conditions section normally states the maximum value of the 200% bonus, which could be £200 for example. If the maximum bonus is set at £200, that is the highest bonus amount the casino will add to the player account. Even if the initial deposit is £200, the 200% maximum bonus is £200, and the new member will start with a bankroll worth £400.
It is also important to remember that if you pay the minimum required deposit, for example. £20, the first deposit bonus will match the deposit by 200%, which equals £40, and provides a start-up bankroll worth £60.
CAN AN ONLINE CASINO CANCEL MY FIRST DEPOSIT BONUS?
Yes, online casinos can cancel a 200% first deposit bonus even if you qualified for the bonus in terms of registering and paying the minimum required deposit. The main reason why any online casino will cancel your welcome bonus is when you breach the terms and conditions. Although, the online casino or slot site could also permanently suspend your account.
The main or most general reason why a bonus could get cancelled by an online casino is when the bonus expires. If you fail to complete the wagering and other bonus requirements within the stipulated period, the bonus is removed from your account.
Odd behaviour or any suspicious activity can result in cancelling a bonus, although, each online casino identifies such activities differently. Most only casinos might consider larger deposits followed by quick withdrawing, without wagering funds as money laundering.
Logging in constantly from a large number of devices could make it appear as if different people share the same login details. Creating more than one account at the same casino is not allowed, although stricter identity verification rules have eliminated such actions.
The use of VPN software is not permitted while registering, depositing, or playing at online casinos. In most cases, players that use VPNs are from jurisdictions the casino can not offer legal gambling services, and therefore the bonus and all winnings from the bonus are cancelled instantly.
CAN I CLAIM A 200% BONUS WITHOUT AGREEING WITH THE TERMS AND CONDITIONS?
By accepting a 200% deposit bonus you agree to the full terms and conditions part of the welcome offers. This includes paying the minimum deposit, activating the bonus via a special bonus code, or accepting the bonus via a pop-up screen.
At some casinos, the first deposit bonus is added automatically to the new player’s account, unless the player contacts support before depositing to cancel the bonus. Although cancelling or not accepting a massive 200% bonus is extremely rare, the reason for such action could only be high wagering requirements. The welcome bonus provides UK players with three times the amount deposited and triple the chances of winning during prolonged play.
Is there a strategy that ensures meeting the wagering requirements of a 200% deposit bonus?
A 200% deposit bonus does not necessarily come with high wagering requirements, UK Gambling Commission licensed online slot sites only require wagering on the bonus. While both the activating deposit and the 200% bonus amount are subject to wagering at other casinos.
Even when the offer comes with reasonable wagering and other bonus requirements, which is one of the main benefits of playing at the best UK online slot sites. Tackling the required wagering with some sort of strategy could allow you to claim your winnings quicker.
The best way to meet wagering within the allowed period is to focus on game types contributing the highest percentage toward the playthrough requirements. At most top 200% deposit bonus casinos, slots could contribute 100%, while table games might only contribute 10%. Study the terms and conditions, play games that contribute the most and do not play any slots that are excluded from contributing towards bonus wagering.
