みんなでNGワードゲーム is a free Android board game developed by yaburits. The game is a simple yet fun conversation game where each player is given a "No Go" (NG) word, and the goal is to avoid saying other players' NG words while engaging in a conversation. The first player to say someone else's NG word loses.

The game offers multiple ways to play with friends, whether you're in the same room or miles apart. You can use LINE or any other calling app to play with friends online while using the app. The game also features an in-app chat function for added convenience. You can also play with friends in the same room by showing each other your phones.

If you don't have anyone to play with, you can use the game's new feature that allows you to create a public room and play with strangers. The game is perfect for various occasions, such as hanging out with friends, waiting in line, or during a break.

Overall, みんなでNGワードゲーム is a great way to spend time with friends and make new ones while having fun.
