the aim of bubble trouble is to get a match of 3 or more bubbles in the same colour touching each other by shooting them upwards. once such a match is achieved, those bubbles fall - along with any others that are attached to just them bubbles (as they have nothing left to hold on to).

use the left and right arrow buttons on your keyboard to change direction of the shooter and press the up arrow button to shoot the bubble. you can use J, K and L instead if you prefer. heres a key to what each of the bubbles do:

  are regular bubbles
  knocks down the first bubble it touches
  is multicoloured - it matches any colour

the first 3 falling bubbles get 1 point each, every additional falling bubble gets 2 more points. you also get 5 points for every time the match-making bubble bounces off the sides.

the game has 10 levels. once a level is cleared, a bonus of 100 points will be added to the score. from level 3 onwards, there will be a time limit meaning that you have to shoot the bubble within 4 seconds otherwise it will shoot automatically wherever the shooter is positioned!

a base line is placed above the score board and if a bubble is touching this line once it has stopped, the game is over.

this game might look easy on the first few levels but it does get much harder! if your score makes it into the top 10 of the day, you will be asked to enter your name. then you can see how well you did compared to everyone else! can you make it into the top 10 of the day or even the top 10 of the month?
