Train Link Slide Puzzle

This is a 3x3 sliding puzzle with a picture of a train.
There are 135 vehicles in total, including 42 Shinkansen trains, 10 linear motor cars, and 83 conventional trains.
The three cars of a three-car train are separated.
Connect them in the correct position according to the icons displayed on the left.
Once completed, the train will run.

Trains appear randomly in various combinations in the game,
so you can keep playing as long as you like.
The number of trains that are shuffled increases depending on the level. It gradually becomes more difficult.
You can also fix the number of shuffles according to the level you have cleared from the settings screen on the top right to prevent the difficulty from increasing.
