Help me out with the math on this...a std pinball playfield is about 20 x 45 for 900 sq inches. These use a 24" LCD, which would yield dimensions of 12 x 20 for 240 sq inches. So a std playfield is about 4 times the area. How do they come up with these being 3/4 size? I assume it is the cabinet dimensions, but the game is played on the playfield, not the cabinet. I mean, could I take a std cabinet, bolt an ipad running virtual pin to it and call it a full sized?
