The Prison 1.91 is renowned as an exciting and tractable Breakout-style game featuring a wide assortment of power-ups, special bricks, and other oddities.

For the uninitiated, the object of the game is to destroy bricks by bouncing a ball (or in this case, a little man trapped in a ball) into them, while keeping the ball from falling off the bottom of the screen.
One of the (relatively) unique points in The Prison's gameplay is that you don't need to hit every brick to complete a level; instead you just need to hit the top border a few times.

Major Features:

1. 60 Internal Boards
2. Windows-Based Board Editor
3. Supports Color and Grayscale
4. OS 5 Compatible
5. Fully Customizable Controls
