Why do IO games lag?

Some players inform that they experience lag when playing IO games. The most common reason is due to a slow Internet connection. Another reason is that the player’s device may not have enough memory or processing power to handle the demands, graphics, or visual effects of the game, especially when there are many players on the same server. Sometimes, it occurs when the server is too full or the ping is high. To reduce lag, players can try closing other programs that are running in the background or connecting to another server location that is closer to their current physical location.
