Simply Gomoku is a board game available for Android platform, developed by Richard L. It is a lightweight version of the classic board game where the aim is to make a row of five before your opponent. The game offers various features including a number of AI with varying playing strength, player vs AI, AI vs AI, and player vs player (hotseat) modes.

The game offers an undo function and pinch to zoom feature. It has sharp and crisp visuals, even on tablets. The game also offers statistics tracking such as win ratio, and has a small memory footprint. The game comes with multiple colors for pieces and interface.

However, there are some limitations to the game. Overlines are not allowed, meaning 6+ stones doesn't count as a win. Additionally, the game currently does not enforce move restricting rules such as three-and-three. The game contains ads but only on menus, none during gameplay. It is important to note that network permission is used only for ads and this app doesn't collect any user data whatsoever.

Overall, Simply Gomoku is a decent lightweight version of the classic board game that offers various features and modes. However, there are some limitations to the game that may affect the user experience.
