 The primary physical difference with Lego bricks is that Tente brick's studs have a small central hole that allow an alternative connection method to accessory pieces.Additionally, although modeled on Lego with nearly identical brick and plate outer dimensions (including the fact that three stacked plates is equivalent in height to one brick), the studs of Tente pieces have a larger diameter than Lego pieces, resulting in them being incompatible.Hasbro marketed the toys in the United States and Japan.
