‘thrufour’ is a 20 piece packing puzzle/brainteaser.

The recommended age is 8 years to Adult but may be played by all ages (except for children under the age of 3 years old due to small parts).

The object of the game is to pack all 20 pieces into the included tray (5 layers, 4 pieces per layer).

However, the pieces also have holes which when aligned may form a pattern where you can see clearly though each of the puzzle layers. There are more than 700 available patterns to solve.

Considering there are 20 pieces with 20 holes… the ultimate goal is to pack all 20 pieces into the included tray so that you can clearly see through 4 holes, hence the name ‘thrufour’.

thrufour may be played in a variety of ways;

Solo - Chill with a cuppa and solve patterns at your leisure.
Head to Head - Challenge an opponent to be the first to solve a chosen pattern.
Collaborative Play - Family members/Friends may collaborate to solve a chosen pattern.
Team Challenge - A team may collaborate to solve a chosen pattern while competing against another team.

thrufour is 3D printed in a range of stunning colours. (There are currently 14 colours available.)
