规则Rules：
标准数独基础上，对于在杠杆上的任一数字而言，其与该杠杆中心的距离（中心格的相邻格算作距离1），乘以其本身的大小称为其力矩。对于每一个杠杆，其两侧的所有力矩之和相等。
Classic rules applied. Additionally, for each number on a lever, its distance from the center of the lever multiplied by itself is called its torque. The cells adjacent to the center is counted as distance 1. For each lever, the sum of the torques on both sides is equal.
