A majority of online casinos in Singapore provide players with two options for accessing their games on mobile devices: an instant-play web version or a dedicated casino mobile app. While there isn't a significant difference between the two options, opting for the instant-play version allows you to start playing right away without the need to download or install any software. On the other hand, the casino app may offer a wider selection of games, but this varies from casino to casino. To make an informed decision, it's best to preview the games available on each platform and choose the one that suits your preferences.
