About Lateral Thinking Together
Lateral Thinking Together is an online multiplayer quiz game where players deduce hidden answers by asking only yes‑or‑no questions. One participant acts as the storyteller (the Game Master), which can be an AI or a human, allowing both solo and group play.
Rooms are private, letting friends join with a code, and the host can tweak time limits, lives, and win conditions. The game blends cooperative questioning with competitive scoring, rewarding quick, accurate reasoning.
01 / THE GUIDE
Creating and Joining Rooms
The player who creates a room automatically becomes the host and can assign the questioner role to a player or the AI. Other players join using the room information, ensuring a private session.
All participants see each other's questions, and the host controls settings such as time limits and required winners. This structure supports both cooperative discussion and competitive play within the same match.
- Try setting a short time limit for faster rounds and more intense competition.
- Use the private room code to invite only friends for a focused experience.

Game Master (GM) Choices
The GM can be an AI, enabling solo play, or a human player when two or more people are present. Selecting an AI GM removes the need for a dedicated host, letting anyone act as a solver.
When a human GM is used, they present the story and answer yes‑or‑no questions, while solvers focus on deduction. This flexibility accommodates different group sizes and preferences.
- Experiment with AI GM for quick solo sessions before gathering a group.
- Rotate the human GM role in longer sessions to keep perspectives fresh.

Yes/No Question Mechanics
All questions must be answerable with a simple "YES" or "NO". The content of each question is visible to every player, fostering shared reasoning.
When a player believes they know the answer, they submit it individually. Correct answers contribute to the accuracy score, which determines competitive ranking among solvers.
- Focus questions on broad categories first to eliminate large groups of possibilities.
- Watch the visible question list for clues about what others are considering.

Adjustable Game Settings
Hosts can select a problem from the provided set and modify parameters such as answering time limit, lives (answer attempts), and the number of players required to win. These options let players raise or lower difficulty.
Changing lives adds a penalty for incorrect guesses, while altering the win‑count changes how many solvers must succeed before the round ends, influencing the competitive pace.
- Lower the lives count for a high‑stakes challenge that rewards careful questioning.
- Increase the win‑count to extend rounds and give more players a chance to solve.

Supported Platforms and Modes
Lateral Thinking Together runs on Windows and macOS via Steam, offering both single‑player and multiplayer modes, including PvP and co‑op. Online play is required for room creation and joining.

- Enable family sharing to let multiple accounts access the game on the same machine.
- Aim for Steam achievements as a secondary goal while focusing on deduction.
