Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.

Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.

In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface.

Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

Cribbage, sometimes called cribbage pocket billiards, cribbage pool, fifteen points and pair pool, is a two-player pocket billiards game that, like its namesake card game, has a scoring system which awards points for pairing groups of balls (rather than playing cards) that total 15.

Played on a standard pool table, participants who a ball of a particular number are required to immediately pocket the companion ball that tallies to 15 when added to the prior ball's number.

The goal is to score 5 paired cribbages out of a possible 8, with the exception that the last ball, required to be the 15 ball, is not paired but alone counts as 1 cribbage.

A mobile device (or handheld computer) is a small computing device, typically, small enough to hold and operate in the hand and having an operating system capable of running mobile apps.

These may provide a diverse range of functions.

Typically, the device will have a display screen with a small numeric or alphanumeric keyboard or a touchscreen providing a virtual keyboard and buttons (icons) on-screen.

Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth or near field communication (NFC).

Integrated cameras, digital media players, mobile phone and GPS capabilities are common.

Power is typically provided by a lithium battery.

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.
