Before writing your own tetris, add 3 star and 5 star pattern, in order to simple limit the size of the 5 star patterns within 4 x4, each pattern is only 16 points, can be said that with uint16_t traverse from 0 XFFFF x0fff 0 after all the pattern out star number wrong, eliminate split into more than one piece design, eliminate repetition, and keep only in the patterns of the lower left corner, to get a complete set and do not repeat graphics, using the lower-left corner of 0 xf000 coding way, the bottom right hand corner of 0 x1000, the upper left corner of 0 x000f, top right corner of 0 x0001, so on the way, each row is the same graphics rotation when four direction, do not understand according to below to speculate:


I put the filter algorithm to 6 star and seven star (4 x4) still limit, all the results are as follows:
