• a plurality of pockets integrated into the board face, wherein:
• the plurality of pockets include a pocket wall defining an opening of a first magnitude, and
• the plurality of pockets are positioned in a grid on the board face;
• at least one peg including a first section and a second section;
• and
• a first end of the peg positioned on a distal end of the first section, wherein:
• the first section of the peg includes a first outer wall with a second magnitude,
• the second magnitude is less than the first magnitude,
• the pocket is configured to receive the first end of the peg,
• the first outer wall of the first section of the peg is indexed to the pocket wall;
• the first end of the peg is configured to press fit into the opening of the pockets,
• the second section of the peg includes a second outer wall with a third magnitude,
• the third magnitude is greater than first magnitude of the opening, and
• the second section of the peg includes a second end of the peg, configured to couple into a hole of an action figure or scene accessory, to be displayed on the board face;
• a stop surface located at an intersection of the first section of the peg and the second section of the peg;
