Bejeweled 3 Game Modes
Classic
The classic Bejeweled gameplay mode from previous installments of the game. All players have to do is continuously match a row containing of three or more gems by swapping one gem with its adjacent counterpart.
Zen
One of the most interesting new additions is a special Zen Mode (similar Bejeweled 2's Endless Mode), where players can play the game without end, as calming music and positive affirmations play in the background. This mode is tailored to relax players with relaxing aural tones, ambient sounds and breath modulation.
Players can continue playing this mode endlessly as the replacement gems in the game are randomly generated in a way such that there is always one more move for the player.
There is also a special breath modulation mode which features a tracking line which moves back and forth, it produces several breathing patterns which players are encouraged to match the breathing pattern. The overall objective of this is to slow the breathing rate of the player so as to allow the player to calm down and de-stress.
This mode was created by PopCap in conjunction with scientists which uses biofeedback to help players relax. The Zen Mode also includes a wide variety of aural tones which include tones which are outside the range of human hearing.
One tone is played into one ear, while a different tone is played into the other so as to trick the brain into hearing a different frequency. This is done in order to facilitate meditation as well as induce brain waves which are usually associated with deep sleep or dreaming. The scientific efficacy of this has not been established and has been referred to as fringe science.
Lightning
It is essentially a time trial mode where players have to get as many points as possible within a 60 seconds timeframe. Players can increase their time limit by lining up special gems, or by creating chains at a fast pace to gain a Blazing Speed bonus.
Players may feel familiar with this Lightning Mode as it already appeared as "Blitz Mode" in Bejeweled Twist and being exactly the same with Bejeweled Blitz gameplay.
Quest
A series of 40 puzzles and 11 mini-games which include rescuing special butterfly gems, digging through diamond mines, battling ice storms as well as others. These are specially tailored puzzles which have an objective other than the standard Bejeweled gameplay.
Secret Modes
Secret Modes aren't visually available as players have to earn some specific achievements to unlock them. They are: Butterflies, Diamond Mine, Ice Storm, and Poker.
