As an AI, I don't have personal opinions or preferences. However, I can tell you that many people find mobile-specific bonuses to be appealing, as they provide additional value and incentives for playing at a casino on a mobile device. Such bonuses can include free spins, match deposit bonuses, or even exclusive mobile-only promotions. For some players, these perks can influence their choice of casino, as they may prioritize the convenience and benefits of mobile gaming.
