在游戏开始前，按下clear键开始点阵像素的扫描，每次显示一个点，在1.6s的时间内将用到的点阵的16个点扫描一遍以检查好坏；

Re(复位键)重新开始，按下时数码管显示分数清0，重新产生第一个方块；

le键实现左移，ri键实现右移；

由于资源限制，采用一个数码管显示分数，每消一行时，数码管分数加一，加到10时重新自动变为0；

用一个拨码开关控制下落的速度，置1时快速0.6s，置0时慢速1s

-Lattice pixel scanned each time a point before the start of the game, press the clear key 16 points of the lattice to be used in the 1.6s time scan again to check for good or bad　Re (reset button) start again, press the digital display scores of clear re-produce the first box　le key to achieve the left, ri, key to achieve shifted to the right　due to resource constraints, the use of a digital display scores, each eliminate a line, the digital control plus a fraction, automatically re-added to 10 to 0　quickly set using a DIP switch to control the falling speed, 0.6 s 0:00 set slow 1s
