If you're a gamer, then you certainly must have a gaming console or a PC that is equipped to handle graphic-intensive games. However, not everyone has the time to sit tethered to a TV all the time. While portable gaming consoles such as the Nintendo Switch and the Steam Deck do exist, they become yet another gadget that needs to be charged and carried around wherever you go. This is where mobile gaming comes in. Gaming smartphones not only fulfill the purpose of a smartphone such as calls and texts, but they are also powerful enough to run mobile games, allowing you to take a breather during the break while at work or even the airport. Whether you're on the train, flight or even passing time in the office, you can play a variety of games to pass the time.
