DIAL SCALE INSTRUCTIONS

The object of this game is to supply 10 portions of nectar to a bee as quickly as you can. The bee moves around the clock a lot, but we can help feed him by moving the flower.

After pressing the <Start> button the bee will come onto the dial, taking nectar from the flower. He will then move to another position on the dial. You can help by moving the flower to the new bee position. This is done by clicking on any one of the characters on the platform. This will cause the character to jump onto the scale, moving the flower clockwise.

When the flower reaches the bee, it will release a small amount of nectar. Your score will increase by one(1) each time the flower reaches the bee. To move the flower counter-clockwise, click on a character that is on the scale.

The bee will not leave the dial until 10 portions of nectar are taken from the flower. After a score of 10 you will be given a score per minute. This is the average number of times the bee can be fed in one minute. Try to achieve a score of 3 or better. A score of 5 or more in one minute will make you a Dial Scale Expert.

This image shows the dial markings between 0 and 1.

Dial Section

Notice that the bee's abdomen falls between 5/8 and 3/4, which is 11/16. The blossom is already at 1/8 (2/16) so you would have to move the blossom another 1/2 (8/16) and then another 1/16. Click on the RABBIT to move 1/2 and the BUTTERFLY to move 1/16 (1/2 +1/8 + 1/16 = 11/16).

Become an EXPERT DIAL SCALE OPERATOR by feeding the bee 5 or more times per minute.

Become a CHAMPION DIAL SCALE OPERATOR by feeding the bee 7 or more times per minute.
