Slider is a puzzle game similar to the well-known Tetris. The essence of the game is to move the appearing blocks of different lengths - so that one or more lines are filled with blocks. When a horizontal row of 8 cells is filled, it disappears and everything above it falls by one cell. When a line fills up, it "burns out" and new blocks appear in its place. The more lines you manage to complete, the more points you get.
In the game slider you need to move the blocks in a horizontal plane. Blocks have different lengths and must fill the free space of the same length. The block itself is moved either with a finger, if it is a mobile phone screen, or with a mouse, if it is a computer.
