Hello everyone!

Suddenly, do you remember slide puzzles?
I think everyone has done it once.
Using the place where only one square is vacant, move the pieces in a snap and arrange the numbers in order.

That's interesting. I'm just crazy about it.
Even though it was finished once, the board is messed up again, and it is said that they are re-arranged from the beginning. That feeling that never ends.
However, isn't it a puzzle that you can play silently by yourself?

Have you ever wondered?
The next person! If you start with, which one can you clear faster? What?

Yes, the "25 puzzle" is what made it into a shape.
With someone all over the world! I tried to fight in.

There has never been an online competitive slide puzzle.
Please enjoy it!
(It's pretty funny)
