I've remade popular casual game Bubble Shooter in vanilla minecraft. Input is exactly as you would in the web game - just aim your mouse and click to send off a bubble!

Objective: Get high scores, clear out the board.

Mechanics: Shoot a bubble - they bounce off the walls and stop when they hit another bubble. A pairing of three bubbles or more of the same color eliminates those bubbles and gives 10 points per bubble. Any bubbles left floating in mid-air after that gives 100 points and is also eliminated.

Failing to eliminate any bubbles in a shot is a faul, and removes one of your faul boxes at the bottom. If you have none, you get penalized by bubbles falling down one step and new bubbles appearing at the top.

If any bubble reaches the bottom of the board, the game is lost.
