King2 is an Android card game developed by Vadim Usov. It is a free game that falls under the category of Card games. The game offers two variants, where you can either play alone against your phone or online with live partners. The online game allows you to play with friends via invitation or anonymously with unfamiliar players at the first free table (quick start). To play online, you need to log in to Google+.

The game consists of 14 parties, divided into two parts. The first seven parties require you to avoid taking certain cards, while the remaining seven parties require you to win those same cards. The game is played with a deck of 32 cards (7 to ACE), which is dealt to four players, eight cards each. The game rules are simple and easy to understand. The first move in the game is randomly assigned, and the first move in the party shifts from one party to another in a clockwise direction. The party ends when all selected meaningful cards are collected. The player with the most points at the end of the game wins.
