Fish games are actually very easy to understand and you have possibly already seen them in-person or online. This is essentially a product that is similar to “skill-based” gaming. In it, you are introduced to an Under the Seas theme where you have to shoot various sea life down with a disproportionately large cannon. The more wildlife you shoot down, the bigger your rewards get.
The skill element comes from the fact that the targets are constantly moving and you would normally want to balance between expense on bullets and the targets you hit.(來源 )
The goal is to ultimately get one of the big fish that will pay much better rewards. The levels are often spruced with various power-ups that will be triggered as part of the game and allow you to balance between aiming directly for the fish or trying to give yourself a leg-up first.(來源 )
Casino operators rely on tiny microchips known as number generators (RNGs) to ensure the unintended effect of spins on online slots. What is RNG technology? Simply put, RNG is a microchip designed to continue to generate numerical sequences, even if the slot game does not play. This set of numbers is fast-paced – and soon means faster than man, billions of times a second!
Random is the key to all kinds of casino games. That is why they are considered opportunity games. It is up to you to win or lose the spin of the reels. Of course, there are casino games where players can influence the outcome. Take blackjack as an example, with several strategies players can use to increase RTP percentages over time. The fact is that while blackjack players can make wise decisions using strategy, you cannot guarantee a winning hand. The shuffling and operation of the cards are unpredictable, as is the spinning of the reels inside the slot game.（原文出處：https://gamerules.com/rng-mechanisms-in-slot-machines-explained/ ）
