Compatibility of maxi sized Mega Bloks Maxi-size Mega Bloks are larger than Duplo. As far as I can tell they have two times the stud pitch and much larger studs:



What, if any, compatibility is there between the maxi-sized Mega Bloks and either Lego elements or the smaller sizes of Mega Bloks?
Yes, maxi sized mega bloks are compatible with LEGO duplo and LEGO system pieces, but only if the duplo piece is 2x2 studs or larger or the LEGO piece is 4x4 or larger. Also, you can only connect LEGO system pieces and duplo pieces to the undersides of maxi size mega bloks.
