The marbles must cooperate in order to survive and not lose lives.
Marbles start with 10 lives, and gain/lose lives. Points are awarded
to the marbles based on performance in marble races. Last one
standing wins! Watch out, as if a marble runs out of lives, then
they are ELIMINATED!!! =D Also, there is a hall of fame for
5-digit scores, so look forward to your marble reaching it!

This starter package comes with:
- 20 Marbles
- 1 Kilometer Track
- Hall of Fame at the end of the track
- Marble Pairing Machine to pair marbles up with each other
- 26 Life Boxes for 0, 1, 2, 3...22, 23, 24, or 25 lives
Courses are not included, but you can customize them however you'd like!
You can make the courses and run the competition yourself, have a go at
it! Anyway, this sure will be a blast! Have fun by clicking the play button.
