■ What is Lights Out?
Lights Out is an old classic logic puzzle game.
This puzzle game is perfect for brain training that you can enjoy as many times as you like in a short time.
The game will be cleared if all the blocks shining blue on the board can be changed to gray blocks.
When you tap the block once, the color of the block in the cross direction changes from the tapped position.
There is no rule except to make all non-grey blocks. Very easy.
Since there is no game over, you can play as many times as you want.
You can always clear it, so let's challenge again and again.

■ Function explanation
We have prepared a gentle stage with a small number of blocks to a difficult stage with a large number of blocks so that brain training is possible.
There are 100 stages in total.
The stage shape will grow as the game progresses.
Use the reset button and the back button if you can't get to the clear on the way.
