Pinball

Pinball is a computer simulation of the titular game where you control two small paddles at the bottom of a rectangular playfield. A ball rolls around, bouncing off obstacles and bumpers. Your goal is to keep the ball in play as long as possible, striking it with the flippers to send it back upward, earning points whenever it collides with certain targets. There is a gap between the two flippers and two more gaps at the far left and right sides on the lower part of the table. If the ball in play rolls off one of those, it’s lost. If you lose all five balls provided, you lose the game.
Unlike what is customary, the player’s score is not represented by digits. Instead, on the left side of the table is a guauge marked with letters, from A to Z. As your score increases, a bar fills the guauge and when “Z ” is reached, the game pauses, your stock of balls is replenished and a the counter goes back to “A”. Each successive successful run is indicated at the center section of the field by the letter “G”, followed by a number and counting incrementally (G1, G2, G3, G4 and so on), while the table layout remains otherwise unchanged.
The game doesn’t provide a way to adjust the power when you launch the ball upon starting, but instead, the trajectory is slightly randomized each time, to feel less repetitive.
