Ddakji

Ddakji is a traditional Korean game in which players fold paper tiles and throw them to flip their opponent’s tile placed on the ground. The game’s origins trace back to the Joseon period (1392–1897).^【1】

Definition and General Features

Ddakji is a game played by two or more players using folded paper tiles called ddakji. The objective is for one player to flip their opponent’s ddakji placed on the ground by throwing their own ddakji. Its use of simple materials has made it especially popular among children.

Materials

The basic materials needed to make ddakji are:

• Thick paper or cardstock (200–300 gsm)
• Square origami paper or any paper cut into a square shape
• Scissors (optional) to create the square shape

Manufacturing Steps

1. Forming the Square

If the paper is not square, fold one corner to form a triangle and cut off the excess to create a perfect square.

2. Folding the Paper into Thirds

Fold the paper horizontally into three equal parts. This can be done by eye or with a ruler.

3. Folding the Corners

Fold the left corner upward and the right corner downward.

4. Preparing the Second Unit

Repeat the same steps on a second sheet of paper to create two identical units.

5. Assembling the Units

Place the two prepared units side by side in a specific arrangement and interlock them.

6. Closing the Flaps

Fold the left and right flaps inward. Then tuck the top flap under the right flap and the bottom flap under the left flap to complete the structure.

7. Result

When correctly assembled, the ddakji holds its shape without adhesive, making it an example of modular origami.

How to Play

Basic Rules

1. One player places their ddakji on the ground.
2. The other player throws their ddakji in an attempt to flip the one on the ground.
3. The player who successfully flips the opponent’s ddakji wins it.
4. If the attempt fails, the turn passes to the other player.
5. The game continues until all ddakji are collected.
6. The player with the most ddakji at the end wins.

Starting the Game

The player who throws first is usually determined by rock-paper-scissors.

Technique and Strategy

• The angle and force of the throw directly affect the outcome.
• It is recommended to aim for ddakji with fuller surfaces.
• Experimenting with ddakji of different sizes helps determine the optimal weight and durability.

Shapes and Game Variants

Ddakji can be manufactured in various geometric shapes. Common shapes include:

• Square
• Round
• Hexagonal
• Pentagonal

There are also traditional variants of the game based on different rules:

• Neomgyeomeokgi: The flipping game
• Nallyeomeokgi: Long-distance throwing
• Byeokchigi: Playing by bouncing off a wall
• Mireonaegi: Push-based game

Educational and Social Dimensions

Ddakji helps children develop:

• Fine motor skills
• Hand-eye coordination
• Turn-taking, sharing, and social communication skills

The folding process teaches basic origami techniques, while the gameplay encourages strategic thinking.

Modern Adaptations

The game has been adapted to digital environments. Online multiplayer versions have been developed incorporating modern gamification elements such as global matchmaking, leaderboards, and daily challenges. While preserving traditional ddakji mechanics, these adaptations emphasize competitive and multiplayer systems.
