In the game Hole.io you play online with other players as a ravenous black hole who devours everything in sight. Drag your finger to move the hole around a city scene as you consume everyday objects like garbage cans and cars, slowly growing to eat larger and larger items. As two minutes ticks off the clock, you'll go from humans to cars to eventually swallowing entire buildings. All you need to do is drag the hole around the map to dominate. The bigger the items you suck up, the more points you get and the larger your hole will become. Get the most points and you win the game.
Towards the end of the 20th century, mobile phone ownership became ubiquitous in the industrialised world - due to the establishment of industry standards, and the rapid fall in cost of handset ownership, and use driven by economies of scale. As a result of this explosion, technological advancement by handset manufacturers became rapid. With these technological advances, mobile phone games also became increasingly sophisticated, taking advantage of exponential improvements in display, processing, storage, interfaces, network bandwidth and operating system functionality.
