Welcome to Bubbos TD! The object of Bubbos TD is to 'pop' all the 'bubbos' before they reach the end of the track. You start with 100 lives and you lose lives for each bubbo that reaches the end.
Place towers that pop the bubbos. Towers cost money. They cannot be moved once they have been placed. Towers can be removed, but not sold. Towers cannot be placed on the path and cannot be overlapping another tower. Drag a tower from the menu on the right to place it. You will lose money when you drop it, and it will be permanently placed.
There are four types of towers you can use. The plain circular towers cost $100. The plain circular towers shoot at bubbos in their range. The eight-toothed gear shaped towers cost $200. They shoot in eight directions (up, down, right, left, and the four diagonals). The towers with an S (for Sniper) on them cost $200. They have a range 6 times that of the other towers. The towers with a dollar sign ($) on them cost $200 each. They give you one extra money for each pop in their range.
The bubbos come in five colors in this order: red, blue, green, gray, and pink. Red bubbos are destroyed when popped. The higher levels of bubbos become one level lower when popped. The higher level a bubbo is, the faster it moves.
In this game there are three difficulty levels and three tracks. The only difference between the difficulty levels is the which and when bubbos come. Harder difficulty levels actually have less bubbos at first and have more bubbos nearer to the end, since you get money for popping bubbos. The tracks have different shapes. They are shown in the order of their difficulty. I have proven it possible to beat impoppable level on S Curve.
