Overview

About this game

"Lateral Thinking Together" is a cooperative and competitive online multiplayer game that challenges your knowledge and deductive reasoning to uncover the correct answer.

What is Lateral Thinking Together?

It’s a detective-style quiz game where players unravel incomprehensible stories by asking "YES" or "NO" questions.

One player acts as the storyteller (host), while the others take on the role of solvers.

Can be played solo!

The Game Master (GM) can be set as either an AI or a player.

By letting the AI take on the role of GM, the game can be played solo.

With two or more players, one of the players can also act as the GM.

Can I ask any kind of question?

Ask questions that can be answered with "YES" or "NO"!

Example: Is he a human? ⇒ NO

Cooperate and compete with friends!

Players compete against each other to achieve the highest accuracy rate. Your skills in reasoning and questioning are the key!

How to Play

1. Create or Join a Room
The player who creates the room becomes the host and can assign the role of the questioner to either a player or an AI.

Players who join the room can choose to play as the questioner or as solvers.

2. Select a Problem and Set the Rules

Players can choose a problem from the problem set to start the game.

Additionally, you can set the answering time limit, lives (answer attempts), and the number of players required to win.

3. Ask Questions and Provide Answers

Players can individually ask questions, and the content of these questions will be visible to all players.

Once a player figures out the answer, they can submit their response individually.

When the number of winners reaches the set goal, or when all players have submitted their answers, the game moves on to the next problem.

Overview

  • Private Sessions: Only players with the room information can join. Enjoy a private experience with friends or acquaintances. You can choose the questioner to be either an AI or a player.

  • Customizable Game Settings: Adjust the challenge level by freely setting time limits and selecting problems.
