There are many games that can be addictive, and the ones that are often considered the most addicting tend to be ones that are easy to pick up, but difficult to put down. These games often have simple mechanics and a high level of replayability. Some examples of such most addicting games include Candy Crush, Temple Run, Flappy Bird, and Clash of Clans. These games are designed to keep players engaged with frequent rewards and a sense of progress, leading to a continuous desire to keep playing. However, it's important to keep in mind that excessive gaming can have negative consequences.
