The top of the board holds five rows of coloured bubbles, and the shooter at the bottom holds the next one to fire. Aim, click, and the bubble flies until it touches the ceiling or another bubble, then snaps into the nearest free space. If it joins a group of three or more of the same colour, the whole group pops. Clear every bubble to win.
Popping a group scores 10 points per bubble removed, so a group of three is worth 30 and a group of six is worth 60. A shot that lands without making a group of three scores nothing but still adds one to the Shots counter, which tracks how efficiently you are playing rather than limiting you. Clearing the board ends the game with a win; if a bubble has nowhere left to snap into, the board is declared full and the game is over.
Three of the same colour connected together, counting the one you just fired. Two will not pop.
No. It only shows the initial direction, so you have to judge the angle off the wall yourself.
Yes. On a touch screen the game shows on-screen buttons, and games played with a mouse work by tapping.
