Can we stop adding extra words that aren't needed (In 1969 reads perfectly well, adding "the year" doesn't really help) and removing spaces from headers:
== Farm == to ==Farm==
Because that is also pointless, and seems to just be to get the badge. Thats not the idea of it. Please be constructive. - Kingcjc 17:24, September 8, 2011 (UTC)
Compatibility with Lego System
The page says "DUPLO is compatible with normal System bricks, but only on the underside of the brick, as the upper studs are all too large". This is incorrect: DUPLO is compatible with Lego System bricks whose width and height are multiples of two studs. They can be attached to both the top and bottom of DUPLO pieces.
The pillars in the (wide) Lego System bricks fit into the inside of the hollow studs of the DUPLO pieces. Bricks that are two studs wide but an odd number of studs long are not compatible due to the internal supports in the piece.
Lego System plates (i.e. 1/3 height pieces) can be attached to the bottom of DUPLO pieces only.
