## Game Board

Blockout - Polypad - Mathigon

## Rules

- Players take turns rolling two dice, and creating a rectangle on the game board with side lengths given by the two numbers they rolled. For example, if you roll a 3 and a 6, place a 3 by 6 rectangle on the gird
- Rectangles cannot intersect or be contained in any previously drawn rectangles. If a player cannot add a rectangle to the board on their turn, the next player takes their turn. If all players pass in a row, the game is over.
- Players get a point for each square they’ve drawn a rectangle around. For example, a 3 by 4 rectangle is worth 12 points. Whoever boxes the most squares wins.

Blockout can be played individually or in groups.
