A 400% deposit bonus casino means either a single deposit or a package bonus that gifts players a boost up to 400%, usually on their transactions to the site. These types of promotions are a registration incentive for new players, who simply need to make a top-up or several consecutive ones through the eligible payment methods. Sometimes, it can also be included in VIP schemes as a reload deal, in which case only higher-tier players will qualify. A promo code could be necessary to activate it, but not always. Rouge Casino is not new and is very well-known among players. Make a deposit and you’ll get a 400% bonus as well as 100 FS on the Narcos slot. This Malta-licensed casino allows you to make a low deposit of just £15, as opposed to the average of £20 among the various casinos, which makes it more attractive.
