Bomb Disposer (Sachen 4-In-1 Vol. 6) - Gameboy Color - Puzzle, Action

If you've ever played Dr. Mario (or its more recent Wii U equivalent, Dr. Luigi) or similar games (Virus Buster in Brain Age), you probably already understand the main gameplay points of this game. Otherwise , here we go... Groups of bombs will fall from the top of the screen. These groups will always come in pairs and the individual bombs within them will be made of one of three colors: white, gray or black. Additionally, each level will have additional bombs already placed (indicated by a slightly fancier design than just white/gray/black). Your objective is to eliminate all these bombs by matching other groups of bombs with them. By placing bombs on top of bombs already placed - by you or by the game - you can line up four (or more) and remove them. By removing all the bombs that the game has already placed, you will advance to the next level. Each level has a number of blocks equal to this: (X * 4) + 4), where X = the number of the current level, as shown in the lower right corner of the screen. If you prefer a "real" level number (i.e. game level 00 = your level 1), the formula is ((X - 1) * 4) + 4. Essentially, it's four times the game level plus four additional. So that's 4 bombs at level 00, 8 at level 01, and 84 at level 20. However, levels 21 to 24 will still have 84 bombs.
