The game released on Windows in 1995 is the reference version for the table rules and PC cheat codes below. The playable version here is Luis Russo's later JavaScript and WebAssembly port, based on the SpaceCadetPinball reverse-engineering work. It presents the Space Cadet table rather than the complete three-table Full Tilt! Pinball package.
The browser port keeps the table and scoring logic but changes the surrounding program: music is disabled, the original game menu is hidden, the table resizes with the window, and R, C, and T were added for restart, the right flipper, and sound effects.
To start a mission, hit one of the three mission targets above the left flipper, then send the ball up the launch ramp to accept the selected objective. Completed missions light the 18-lamp progress ring; filling it promotes you through nine ranks, from Cadet to Fleet Admiral. Available missions and their required shots change as your rank rises.
Scoring is not only about random bumper hits. Repeatedly clear the three field-multiplier drop targets in the upper-left area to move through 2x, 3x, 5x, and 10x. The highest lit multiplier steps down after 60 seconds, so a valuable multiplier should change which targets you pursue.
Extra balls and table advantages come from deliberate target sets. Completing the medal bank for a third commendation awards an extra ball, while repeated hyperspace shots can activate the center post, light extra-ball lanes, and eventually turn on the gravity well. Active missions require fuel, which can be restored through the fuel chute or by lighting the fuel targets.
