The Playing Board

Q-Bust              Game board

Object of the Game

  • Collect points and try to complete as many missions as possible.
  • A mission is considered to be completed once you have pieced together all of the pictured cube formations.
  • The mission panel is updated after each cube formation is successfully completed.
  • You are given 5 minutes to complete as many missions as possible.


You must complete one mission per level.

Q-Bust              Missions

The mission panel can be found on the right-hand side of the screen.
It displays the following:

  • How many cubes of each particular color still need to be formed. A cube formation is created by lining up at least 3 like-colored cubes in a row or around a corner.
  • How many star cubes still need to be cleared. Star cubes can be cleared by creating a cube formation that includes at least one star cube.

As soon as you have cleared all of the required cube formations and star cubes, you will reach the next level.

The difficulty increases with each level.

You will receive points for each successfully completed formation.

How to play

You have already learned how to arrange cubes in Tetris
but make no mistake: Q-Bust is all about becoming an expert in creating three dimensional cube formations.

How it works:

  • The playing board is square and has 7 rows that each have 7 spaces.
  • You can always slide your cube onto the playing board from 2 sides.
  • Each cube slides onto the playing board until it hits another one. If the one it hits is a single cube, then that cube will be shifted one position further.
  • If the current cube does not fit on the playing board, then the game will automatically end.

Rotating the playing board

Q-Bust              Rotating the playing board

By clicking this button, you can rotate the playing board by 90 degrees. This button can be found on the bottom, right-hand side of the playing board.

Normal Cubes

Q-Bust              Normal Cubes

There are blue, green, red, and purple cubes that can be used to create cube formations with one another.

The Gray Cube

Q-Bust              The Gray Cube

Gray cubes have a fixed position and cannot be moved. Gray cubes are not color cubes.

The Fire Cube

Q-Bust              The Fire Cube

By using the fire cube, you can melt away all movable cubes in a row. The fire cube is quite useful if the playing board is already very full and you barely have any room left to slide more cubes onto it.

The Color-Changing Cube

Q-Bust              The Color-Changing Cube

Color-changing cubes have the ability change the color of the cube that they slide into on the playing board.

Here is an example of how you can use them:

The Star Cube

Q-Bust              The Star Cube

If you clear a formation that contains a star cube, you will receive 25 bonus points as soon as you reach the next level. Be sure to pay attention to the mission panel, as it tells you how many star cubes still need to be cleared in order to complete the current mission. You are only given as many star cubes as there are lying on the playing board at the beginning of the game.

Game Scoring

In addition to the points that you are awarded for completing missions, you are also given further points for all other cube formations that you complete.

  • Q-Bust                      Game Scoring

    The amount of points you will receive depends on the length of the cleared cube formations as well as which level you are currently playing in when they are cleared. The amount of points you will receive per cleared formation is calculated as follows:

    Amount of cubes² x current level number

    A 5-cube formation, the longest cube formation possible, that is cleared in level 2 will be rewarded with a 50-point bonus. In level 5, the same formation would be much more difficult, and as such would be rewarded with 225 points.

  • Q-Bust                      Bonus

    As soon as you have reached the next level, you will receive bonus points . The amount of points you will receive depends entirely upon how well you have played in the level. The bonus points are calculated as follows:

    5 x current level number x amount of cubes in the longest formation cleared

    If you clear a 5-cube formation in the third level, you will be rewarded with 225 points.

    In addition, you are also given 25 bonus points for each star cube that is included in any cube formation.

    If you try to slide a cube onto an area where there is no room (the position is already occupied), then you will lose 5 points.

Strategy and the ability to plan cube formations are necessary skills in Q-Bust. Good luck!
