LEV     TREN        

TREN is a logical puzzle invented by Shinichi Aoki (Japan). The Japanese name of this puzzle means "parking". Every digit is a part of a car and the grid is a parking space.

The goal is to extend the cell with a digit to cars of size 1x2-cells or 1x3-cells. The digit indicates the number of possible movements of the car.

Cars can drive forwards and backwards.
