They are individual high qualtity original art tiles. The numbered 1 to 6 trap door pieces are seperate squares. Each tile is felt backed on durable board game material.

There are 20 different board tiles (including two pieces that can be used as endzones). There is a 21st piece to use to add a gaping pit to any room. Pieces 22 to 27 are the numbered trapdoors.
A great set that I have heavy doubts if more will be made.
Auction ends tomorrow.
