Gomoku
Gomoku, also called "Five in a Row", is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board, using 15×15 of the 19×19 grid intersections. Because pieces are not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
Pokémon Go
Although the game is free to play, it supports in-app purchases, where players can purchase additional Poké Balls and other in-game items. These items include Incense (which attract Pokémon to you as you move for thirty minutes), Lure Modules, to attract Pokémon to a fixed location, and Lucky Eggs, which double experience points gained for a thirty-minute period from use. All Pokémon are displayed with a Combat Power. A Pokémon's Combat Power is a rough measure of how powerful that Pokémon is in battle. Generally, as players level up, they catch Pokémon with higher CP.
