Even though both Keno and slot games in online casinos are chance-based games built around the concept of Random Number Generation, they are generally categorized as different types of casino games due to differences in gameplay. In the online casino Keno, you pick numbers and click “Play” to start the draw, placing a bet on your chosen numbers being selected. This can be compared to a slot game, where you place a bet, and then the game’s RNG determines the outcome of your spin. So, in essence, while the core mechanics of chance and betting are similar, the presentation and player interaction differ.
