I searched Pinside and found no previous mention of this, so here goes:

I bought a refurbished Amazon Kindle Fire ($40 on woot.com that day) to use on the can, as my older tablet wouldn't run Pinball Arcade.

I was quite pleased to find that Amazon has its own version of the game in what's called the Amazon Underground, where Kindle users can download games that are actually free. (Maybe it mattered that I also belong to Amazon Prime, not sure about that...)

But the list of tables included for no additional charge just blew me away:

Attack from Mars
Big Shot
Black Hole
Black Knight
Bride of Pinbot
Cirqus Voltaire
Creature from the Black Lagoon
Elvira and the Party Monsters
FunHouse
Genie
Gorgar
Harley Davidson Third Edition
Medieval Madness
Monster Bash
No Good Gofers
Ripley's Believe It or Not
Scared Stiff
Star Trek the Next Generation
Tales of the Arabian Nights
Taxi
Theatre of Magic
Twilight Zone

Pretty awesome selection for free, I think! No way to add more titles, but still! The variety of top titles included should suffice!

If anyone knows whether other tablet owners can get this, with or without Prime, please enlighten us!

One self-enlightenment later, now I'm playing it on my Android phone too, just had to use the Amazon App Store. So the Underground must be a feature of having Prime.

And it dawns on me that the games included were the regular game's First Season plus the Launch Tables, all unlocked.
