Wahoo (Aggravation) Board Dimensions: Standard 12×12 Hole Grid

The standard Wahoo (also known as Aggravation) game board is a 12×12 hole grid—meaning 12 rows and 12 columns of playing holes (144 total holes).

Physical Dimensions (Typical)

• Board Size: ~18–20 inches (45–50 cm) square.
• Hole Diameter: ~0.5–0.6 inches (1.3–1.5 cm) for standard marbles (9/16" or 14mm).
• Track Layout: The 12×12 grid forms a cross-shaped track. Each arm has a "start" area (4 holes), a "home" stretch (4 holes), and the main circuit uses the perimeter and center rows.

Variations

• Vintage/Handmade Boards: May be 16×16 or 20×20 holes for 6–8 players (more marbles per player).
• Travel/Magnetic Versions: Smaller (10–12 inches), smaller marbles.
• Deluxe Wooden Boards: Often 18–22 inches with carved wells for captured marbles.

Key Point: The 12×12 hole grid is the defining standard for classic 4-player Wahoo/Aggravation. If you're building one, space holes 1.25" center-to-center for comfortable marble handling.
