Our Game Board templates have been broken for a while and we have been meaning to fix and replace those links, but COVID-19 put that on the back burner unfortunately.
In the meantime game board set up is very simple and a template is technically not required. Just create a file that is 18"x18" as its overall size and have the resolution set to 300DPI. Then account for 0.25" of bleed on each edge so your actual workable artwork will be sized at 17.5"x17.5" on the board. We can tweak the artwork slightly while we are setting them up for print so as long as you are around these specs you will be good to go.
The same applies to the larger 17"x22" game board, just with the overall numbers adjusted accordingly.
If you have any questions or concerns about that just let us know!
