There are sixteen playfields on each of the 40 levels. The last playfield
on every level is a Challenge Playfield – a bonus playfield designed
to reward you for fast puzzle solving skills. You will be awarded 50,000
bonus points for completing each Challenge Playfield within 30 seconds. However,
if you do not complete the Challenge Playfield you can either try again
or continue on to the next level. There is no penalty for not completing
the Challenge Playfields which in some cases are very difficult.
Remember that on many Challenge Playfields you will have to use the Gem
Drop feature several times. Also, you will find yourself using the
Undo feature often. In order to be most effective, you will need to
learn the shortcuts for the Gem Drop and Undo features:
You can play through all 40 Challenge Playfields in succession by turning
on the respective radio button in the Settings menu. That is, click
on the Settings button on the title page. Then, turn Challenge Playfields
Only to On. Press Done in the Settings menu. Now start a new game
from the title screen by selecting New Player. High scores and levels
reached will not be saved when Challenge Playfields Only is set
to On.
