common user could not decipher between the two games. Any differences between the two are slight and insignificant. If one has to squint to find distinctions only at a granular level, then the works are likely to be substantially similar. Reviewing the videos of the game play bolsters this conclusion as it is apparent that the overall look and feel of the two games is identical. There is such similarity between the visual expression of Tetris and Mino that it is akin to literal copying ... In particular, the style of the pieces is nearly indistinguishable, both in their look and in the manner they move, rotate, fall, and behave. Similar bright colors are used in each program, the pieces are composed of individually delineated bricks, each brick is given an interior border to suggest texture, and shading and gradation of color are used in substantially similar ways to suggest light is being cast onto the pieces.
In any case, what seemed decisive to the actual finding that Xio had infringed Tetris Holding’s copyright were the similarities in the look and feel of the two games (which were held to be tantamount to literal copying), rather than sole reliance on the idea/expression dichotomy.
