There are 20 blocks in the game board, arranged in a 4x5 grid, with 4 different colored shapes:

1. Red block
2. Yellow block
3. Green horizontal rectangle block
4. Blue vertical rectangle block
At the beginning of each game, a red block will always appear, while the quantities of the other three shapes may vary. Additionally, there are two empty spaces outside the shapes.
The objective of the game is to slide the shapes in order to move the red block to the queen position at the center-bottom of the game board. Once achieved, the game progresses to the next level.
There are two game modes: Random Mode and Challenge Mode.

In Random Mode, clicking the left arrow or right arrow button will randomly select a level and generate a new game, resetting the timer and step counter.
In Challenge Mode, clicking the left arrow button will go back one level in the current game, resetting the timer and step counter, and decrementing the level number. Clicking the right arrow button will advance one level in the current game, resetting the timer and step counter, and incrementing the level number.
The Reset button will reset the current game scene, resetting the timer and step counter, while keeping the level unchanged.
