How it works is you race around the board... first one to the finish line wins... you always move 0 to 3 spaces on each turn... so your objective is to move as many spaces as you can (3 being the best, 2 second best, etc)
An example trivia card is:
HOW MANY SPACES DO YOU WANT TO MOVE?
A. The number of hearts in an Octopus
B. The number of countries that border the Sargasso Sea
C. The number of dogs that survived the Titanic
D. The number of people named Oscar to have won an Oscar
One of those are 0, one is 1, one is 2, and one is 3. You only have to answer A, B, C or D -- find out the answer and move that number of spaces!
Part of the educational experience is using knowledge you have to find out what you believe will give the most spaces. You might say well I know an octopus has to have at least one heart, so that one can't be zero... etc etc... and rationalize which one might be the higher number.
If you choose A, the card reader reveals that there are THREE hearts in an octopus and you move 3 spaces! Plus you just learned something.
Had you chose B, you would have learned that the Sargasso Sea floats in the middle of the ocean, and thus no countries border it. You wouldn't have moved any spaces, but you did learn some geography!
Had you chose C, you would have got to move 2 spaces when revealed that two dogs survived the Titanic... or choosing D would have gained you one space in the game and you would have learned that Oscar Hammerstein is the only person named Oscar to win one.
