The Launch of 'Ninuki Renju': A New Online Game for 2–4 Players

The Release of 'Ninuki Renju'

Qdan, a leading company in the online party game sector with approximately 360,000 monthly active users as of April 2026, has just added a new title to its lineup. Launched on May 20, 2026, 'Ninuki Renju' becomes the 39th game featured in the popular party game app 'Dokopa'. As a unique take on the classic board game Gomoku, this game allows 2 to 4 players to engage in witty competitive play in both individual and team formats.

About 'Ninuki Renju'

'Ninuki Renju' is a strategic board game that builds on the fundamental mechanics of Gomoku, which is widely recognized for its five-in-a-row gameplay. This modern version, however, introduces a clever twist: players can capture their opponent's stones. The winner is determined either by lining up five of their own stones or capturing ten of their opponent's stones. The added element of capture creates a new depth of strategy, transforming the game into a captivating brain challenge.

Key Features of 'Ninuki Renju'

1. Enhanced Tactical Gameplay
The core aspect of 'Ninuki Renju' is its capture rule. Players can eliminate an opponent's stones by sandwiching them between their own. This means that simply trying to create a line of five isn't sufficient for victory; players must balance offensive strategies with defensive maneuvers. The game offers a straightforward look but opens the door to intricate strategic possibilities.

2. From Two Players to Four
Traditionally enjoyed as a two-player game, 'Ninuki Renju' now accommodates 2 to 4 players through rules adapted from the American game 'Pente'. This means players can engage in one-on-one battles or team-oriented matches, much like doubles in table tennis. Teams will alternate turns to strike, making for an engaging and collaborative gaming experience.

3. Customizable Gameplay
Players can tailor their game settings according to their preferences, choosing from board sizes (15 or 19 lines), the option of forbidden moves, mandatory or optional captures, and the handling of long connections (six or more stones in a row). This flexibility allows for both classic and relaxed play styles, catering to all skill levels and preferences.

Historical Significance of 'Ninuki Renju'

Originating during the Taisho era, 'Ninuki Renju' reflects Japan's rich history of traditional board games. Evolving into the popular American game 'Pente' after World War II, it highlights the game’s international journey. Despite its lesser-known status in Japan, 'Ninuki Renju' has gained recognition abroad, being a significant game in the context of popular board gaming.

In 1977, the game 'Pente' took inspiration from 'Ninuki Renju', becoming a sensation in American gaming circles, dubbed the 'Backgammon of the 1980s'. However, 'Ninuki Renju' itself rarely found online popularity, until now, when 'Dokopa' presents it as a fun and accessible option for players worldwide.

'Dokopa' and Its Expansion

'Dokopa' is not just a casual gaming platform; it's an environment where various types of games—including classic board games and newer party games—are available to players. With the addition of 'Ninuki Renju', the app continues to diversify its game offerings, enriching its catalog of traditional gaming experiences.

For those who are new to 'Dokopa', the app allows friends and family to connect and play various games together in a safe and secure setting. As of April 2026, the app has garnered considerable popularity, with an active user base reflecting its appeal.
