This is actually a web port of Space Cadet for Win 9x which has sort of a prerendered 3d look but is still basically a 2d table, as opposed to stuff like Pinball Arcade or the FX compilations by Zen.

There's a set of lights in the lower left-hand edge and on the very upper right-hand edge. When it's time to select a mission look for the yellow arrow near those lights. Hitting the lights lets you select a mission. Sending the ball up the ramp confirms the mission. I don't quite remember what the missions were - typically "hit some combination of things" - but they were worth a lot of extra points and/or an extra ball.

I am of the impression that the mission is defined by having the pin ball hit the places where the blue arrow points within a set amount of time.

It's a bit of a shame that Microsoft only licensed Space Cadet Pinball from Cinematronics for Windows 95 and XP [0].

Do you see the flashing arrow? You have to hit one of those tiles, and then launch the ball up the ramp.

Where did you see missions?

Definitely did - that MIDI file is etched into everyone's soul who played Space Cadet but this was early days, maybe it's possible the win9x machine you played on didn't have a sound card?

EDIT: From what others have said it sounds like it's off by default. It's been decades so I don't remember.

Apparently it did, but it was turned off by default since it could have a performance impact on slower machines.

Yes. It's original.

Does x help you avoid that deadspot in the middle, where the flaps cant reach?

Does the shaking even do anything in this game?

Exactly what I was looking for for my non-US keyboard :)

if you're playing on a phone, the right side of the window might be cut off. you could rotate the screen, or you could select the desktop version in Chrome options (but it will be very small).
