用于检索游戏“俄罗斯方块”中，前8块块效率可以达到1.125的所有摆法。

块效率计算公式为

块效率= 总攻击行数/(总块数/3)

注：一次消3行或者4行为攻击行数-Used to retrieve game " Tetris"　in the first eight horizontal efficiency can reach 1.125 of the pendulum method. Block efficiency is calculated as the block efficiency = total attack of the number of rows/(the total number of blocks/3) Note: A destructive attack line of line 3 or 4 acts
