Easy ranks:
-----------
In story mode you can only gain one rank per game. Once you go up one rank
(usually after reaching the goal within two minutes for a second time) just
top out, watch the scenery change, and start again to gain another rank.
Indefinite flips:
-----------------
When a piece reaches the bottom, you can turn it indefinitely, giving you
more time to think.
