# How to Play Tic Tac Toe on Cosmos Video

Tic Tac Toe on Cosmos Video is a 2-player head-to-head game played on an expanding infinite grid instead of the classic 3x3 board. Players race against a quick move timer to connect 5 in a row, which almost eliminates draws. It runs inside a Cosmos Video space at a game table with no extra setup.

## Rules

1. Two players alternate turns placing X or O on the grid.
2. A quick move timer runs each turn; play fast or forfeit your move.
3. The grid automatically expands as new moves are made, so the board never fills up.
4. The first player to connect 5 marks in a row, horizontally, vertically, or diagonally, wins.
5. The infinite grid means draws are extremely rare.

## Setup in Cosmos Video

1. Enter a public Cosmos Space or create your own.
2. Walk up to a game table with the gamified appearance.
3. Press X on the keyboard, or click Games in the toolbar.
4. Select Tic Tac Toe and invite an opponent to the other seat.

## Tips for Groups

- Think in multiple threats; set up two potential 5-in-a-rows at once.
- Block early, especially when your opponent gets 3 in a row open on both ends.
- Use the quick timer to your advantage by forcing hasty moves from your opponent.
- Great for a 5-minute tiebreaker after other games.
