Twenty One Welcome Bonus Code

Terms and Conditions

The Twenty One Welcome bonus currently consists of a bonus of 121% up to £100. The minimum deposit that will trigger the bonus is £10. This bonus has a wagering requirement of 35xbonus for the deposit bonus. The bonus is structured so that only wagering with bonus funds, which are stacked beneath the deposited funds, counts towards the wagering requirement. This also means that bonus restrictions, do not apply while you are wagering with your deposited funds. In other words as long as you are only using deposited funds you can withdraw at any time you like. (The standard bonus structure where all funds are locked until wagering requirements have been completed are used for non-UK players.) The maximum allowed bet is £5 on any single round of play. There is no maximum win on the deposit bonus. Bonus funds and associated winnings will expire after 30 days if the wagering requirements are not completed. The bonus is cashable. Players depositing via Neteller or Skrill are not eligible for this bonus. Bonus funds and any associated winnings will expire after 30 days if the wagering requirement has not been completed.

Simulations

Our review will provide a value for Low Rollers, Mid Rollers and High Rollers. Each category will use the same slots game (Thunderstruck) for accurate comparison. Low Rollers will use the minimum possible bet size (£0.09/spin) and a low deposit value of £30. Mid Rollers will use an average player bet size (£0.54/spin) and an average deposit value of £50. High Rollers will use a player bet size (£4.95/spin) and a deposit value of £100.

 

 

Deposit Bonuses Due to the structure of the Twenty Once Casino bonus where wagers with deposited funds do not count towards the wagering requirement the bonus has to be assessed in two parts: the pre-bonus wagering and the value of the bonus. Once we have conducted these simulations we work out the value of the bonus as follows: [Expected Loss from pre-bonus play] -([Value of the bonus]x[Chance of using the bonus]) = [Average Expected Value for the bonus] Low Roller Bonus Using a deposit of £30 with a bonus of £36.30, with a wagering requirement of 36.30x35 = £1270.50 and a bet size of £0.09/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus: Average Expected Value for the bonus = -£22.88 + (£13.47x0.9562) = -£10.00. Mid Roller Bonus Using a deposit of £50 with a bonus of £60.5, with a wagering requirement of 60.50x35 = £2117.50 and a bet size of £0.54/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus: Average Expected Value for the bonus = -£18.26 + (£33.42x0.8950) = £11.65 High Roller Bonus Using a deposit of £100 with a bonus of £121, with a wagering requirement of 121x35 = £4235 and a bet size of £4.95/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus: Average Expected Value for the bonus = -£16.48 + (£87.32x0.8871) = £60.98
