JumpStart Adventures 3rd Grade: Mystery Mountain is a personal computer game in Knowledge Adventure's JumpStart series of educational software. As the title suggests, the game is intended to teach a third grade curriculum. This is the only version of this game created and, unusually for Knowledge Adventure, is still being sold over fifteen years after its initial release in 1996. It is currently included as the 'Fundamentals' disc of JumpStart Advanced 3rd Grade.
Set in a retro-futuristic universe, the game concerns Polly Spark, the bratty daughter of an apparently very wealthy inventor, and her attempt to alter history so that her inane answers to a history quiz she failed will be correct. To do this, she sends twenty-five reprogrammed robots back in time and, with her father conveniently away on a business trip, she takes over Mystery Mountain, the literal 'mountain mansion' where she and her father live. The goal of the game is to help Botley, the robot assigned to keep Polly under control, save the world by retrieving each of the twenty-five robots and bringing them back to the present.
The characters from this game were later featured in JumpStart Typing.

guys i managed to installed it by following this instructions once I've downloaded it. I didnt use any virtual drive etc. I simply see the nature of the file and search for it on how to open. look this youtube vid below. https://www.youtube.com/watch?v=hu_URc7RNtA

Downloaded it worked then now it's telling me to insert disk why? Can anyone help?

SlowPoke2020-04-070 point

Great game, I got this for my son, because I have such fond memories of this game.
Easy to download, you will need an ISO drive, I like Virtual Clone Drive (FREE). Then you will mount the ISO (download) to the Clone Drive.

I bought the cd-rom for this game but can't figure out how to install it? Nothing happens when I put the disk in. I have Windows 10.

highlady2020-03-121 point

So I do what LadyAllen said, and I click the AUTORUN.EXE and the start-up menu comes up, and I click 'Install', I allow it via the pop-up for the system admin to do this, and then it closes and nothing happens, nothing installs. Help!

LadyAllen2020-02-091 point

Works perfectly, thanks! For those wondering how to run this on a Windows 10 machine, you can use the .iso file by right-clicking scroll to Open With select Windows Explorer. This will mount the .iso to a virtual drive on your computer so you can run it like an old-school CD-ROM. Just navigate to the drive (in my case, it was the E drive) and click AUTORUN.exe to install the game and get started. Enjoy!

I loved playing this game with my cousin! Such fond memories.

LOVED THIS GAME WHEN I WAS IN SCHOOL

Geolicious2019-10-031 point

I did not expect to see this many comments in 2019! I remember learning the origins of gum from some game in my childhood, after 20 minutes of research I found it! I can't wait to play it again! But I can see there are some issues with the download. I'll let y'all know if I'm successful. I don't know which version of the game I played, but it was probably the 2001 one. I probably got this game in 2007 when I was 8 years old.

jorp2019-09-203 points

instead of saying you got the game to work, please say how you got it to work or don't say anything at all. thanks

Apoc2019-09-080 point

Cant Believe this game still works on Windows 10.

Rachel2019-08-18-1 point

I'm having issues downloading this game and I would love to play. Can someone help me? I have a Dell

Jeff2019-08-150 point

@JDLMON3 I can confirm that this download is the 2001 version; the original 1996 version had more dialogue and different graphics. This one also contains online activities that I don't think were included in the original (I could be wrong about that one though).
If you were willing to upload your copy, I and others would greatly appreciate it.

jdlmon32019-08-030 point

TOUGHSUN14 I still have my original 1996 copy. What is the difference?

ToughSun142019-06-091 point

Okay, while this is a true copy of the game, one gripe I do have about it is it's not actually the version I remember. From what my research tells me, this is actually the 2001 version of the game, not the original 1996 version of the game. So, there's that. If someone could find a copy of the 1996 version, that would be appreciated.

Hi, I'm new to the world of playing older games on new devices/OS's. I have the latest version of Windows, and I'm not sure how to play this? Is there another software program I need to download in order to play the game I loved as a kid? Please help!

botly fan2019-03-06-1 point

hi plz disregard the my comment thats below this one. i found out how to use the iso file and got the game to work (welcome back botly,i missed you old friend.) ps im 18 so i am mostly playing for nostalgia,not for a challenge.

Photo Game Face, a new feature of Tiger Woods PGA Tour 08 for Playstation 3 and Xbox 360, lets you use photos of your face to create an ultra-realistic likeness. Tiger Woods PGA Tour 08 for Mac. May 14, 2007  Tiger Woods PGA Tour 2005 for Mac simply doesn't work. It stopped working a mere few months after its initial release when Apple's QuickTime stopped supporting a feature/function used by the game. Feb 13, 2014  Golf, Whenever You Want It - Tiger Woods PGA Tour Online is designed to work around your busy schedule! Fire up the game and squeeze in a few holes from the world's most legendary courses. Suspend your round and resume it the exact same point anytime. Jun 12, 2012  Tiger Woods PGA Tour 12: The Masters is a multiplayer golf game for Mac that allows players to step into the shoes of some of the greatest pro golfers on the PGA tour as they go for the ultimate prize in the sport, the Masters title. Play championship courses like Augusta National Golf Club, Royal Melbourne Golf Club (Australia), Atlanta Athletic Club, TPC San Antonio, St Andrews Link. Review Feb 02, 2014  The game could not be played effectively because of the mouse situation. I have Tiger Woods 12, and it has a 3 click mouse, so I assumed the new game would as well, but it didn't, and I could not begin to compete with a third grader. I ordered an 8 button game pad, but it would not work either. I wound up getting refunds on booting items.

botly fan2019-03-050 point

i downloaded this but all i got were 2 iso files. are they the game or do i need to do something else to play the game?

sebabstian2019-02-08-1 point

i've been looking for a good copy and download of this game for 5ever. I lost my copy of it well over a decade ago and have been itching to find a new copy since. I only ever got through like five robots as a child and as an adult, I'm ready for a speed run

Kayla2019-01-30-1 point

Molcrux2019-01-300 point

Does this come with other languages than English? I'm from Norway and played this a lot when I was younger, but I can not find it anywhere..

Bee2019-01-133 points
