Chess Die Net - D20 icosahedron - A4

This Chess Die Net, D20 icosahedron, can be enlarged or reduced as required.

The use of card for printing and assembly is recommended, but normal paper can also be used and then glued on card for extra solidity.

Chess Dice is a popular chess variant, and can be used as a fun and didactic activity in chess lessons.
This A4 resource can also provide a rich cross-curricular activity, where chess, maths, origami, art, physics, design and technology are present.
The figurines and backgrounds can be decorated, if required.

Instructions for assembly.
Cut around the net along solid lines.
Scoring along dotted lines is recommended to make folding easier. The use of a sharp blade is not recommended for scoring, as it can easily over-score and cut through card.
The following tools can be used for scoring safely: the edge of a plastic spatula, the lid of a Bic pen, a pen-shaped staple remover…
Fold, glue and hold together till attached.

Rules of Chess Dice for D20.
All moves must be legal.

If you get black, you can choose what to play (John Foley rule).

Original basic version: roll the die and play what you get. if you can’t make a legal move, you roll again. If you wish to castle, you need a king, or a rook, or black.

Advanced John Foley version: roll the die and play what you get. if you can’t make a legal move, you can choose what to play.

I published the concept of Chess Dice Nets on 6th April 2021.
The figurine drawings, sizes, their distribution and orientations are my own work.
The requirement to create D12 and D20 chess dice was requested by John Foley.
The optimal frequency of figurines for D12 and D20 was calculated by WIM Rita Atkins.
