How to Play (TL;DR Ver.):

Make pairs (can be played 2 or more players)
Rock, paper, scissors, winner goes first
Winner makes a sentence / says a word / whatever prompt you can come up with
Winner draws a line on the grid
Then it’s their partner's turn to do the same
The game continues until there are no more boxes to claim (or the game finishes until a player reaches an x amount of points first)
The player who gets the most points/reaches x points first wins
When the pair finishes one sheet, they come up to you to get a brand new sheet

Points:

There are some squares with bonus points, if the students can claim it by making a square, they can get the points.
- 2 Fingers = 2 points
- 3 Fingers = 3 points
- 5 Fingers = 5 points
- Poop = -1 point
- Claiming a blank box = 1 point

Attachments

15 different dots and boxes grids (Plain = no bonus points, Bonus = has bonus points)
Basic Grid + Instructions
Worksheet Templates (3 versions) Ver. A&B: Has a score tracker Ver. C: Has no score tracker, means there's more space to work with

NOTE:

Printing Dots and Boxes Worksheet is optional but it'll be helpful with keeping track of points for each round.
Dots and Boxes Board + Instructions is shared between one pair.
I got the bonus points idea from a user on this site but I can’t find their activity anymore. If this is you, please let me know so that I can properly credit you!
The PPT includes both an English and Japanese instructions tutorial straight from the game.
To save paper, you can laminate the sheets and have the students use texters or markers to write on it. When they finish a round, they can erase it and get a new grid from you or use the same sheet.
If you want the DOCX files, I'm more than happy to upload them!
