■What kind of game?
It is a game like Tetris.

■Description of the game
There are 21 squares x 10 squares. Blocks are falling down, so please align the blocks so that they don't fill up. I think it is easier to understand if I explain about Tetris, so I will explain about Tetris below. Please read it for details.

What is Tetris?
Tetris is a puzzle game invented in 1984 by Alexey Pajitnov, a computer scientist in the Soviet Union. Players move square blocks falling from the bottom of the screen left and right, rotate them, and stack them on top of each other to erase them by aligning one line. New blocks will fall as they are erased, and the objective is to erase as many as possible. The game is over when the unaligned blocks reach the top of the screen.

Tetris is popular all over the world because of its simple rules and the high level of concentration required. It can also be played on a variety of platforms, making it popular among a wide range of people.

■Reviews from acquaintances
First of all, the graphics are very nice. Like retro Tetris, the blocks are just the right size and the entire screen is easy to see. And it is nostalgic.

The game play is also very comfortable, as no ads are displayed on the game screen.

All the elements of Tetris are present and the controls are smooth. And I find the game stages to be of the right difficulty level.

In addition, the sound is excellent. The nostalgic Tetris theme music plays very well.

I like this app very much.

■Disclaimer
Tetris is 20 squares by 10 squares, but this game is 21 squares by 10 squares. Therefore, it is not Tetris because the game elements are different.

The background music is free. It is not an arrangement of Nintendo's Tetris music, but an arrangement of the original Korobuchka.
