These are the different game modes in Candy Crush Soda Saga:
Bubblegum
Rid the game board of Bubblegum. There are three levels of stickiness:
One layer of Bubblegum: Remove by matching the Candy on the Bubblegum with at least two candies of the same color.
Two layers of Bubblegum: this traps the Candy underneath it. Match the Candy under the Bubblegum with two or more candies of the same color to remove a layer. Repeat to fully remove the Bubblegum.
Three layers of Bubblegum (the thickest and stickiest stage): Remove in the same way as above. But watch out: this sticky stuff can spread, adding a single layer of Bubblegum to adjacent candies.
Honey
Your goal is to collect and free all the Bears that have been covered in Honey. Match beside the Honey to release the Bears. See the number of honeycombs on each space to know how many matches are needed to fully remove the Honey!
Jam
Fill the entire board with Jam! One Jam square appears behind a random Candy. Every time you switch that Candy in a successful match the Jam will spread to behind the matched Candies. Special Candies spread Jam on all squares they affect. For example a Striped Candy will put Jam on an entire row or column.
Chocolate
As sweet as it sounds, the Chocolate game mode can be seriously tricky. This Candy treat can spread like wildfire, covering all Candies in its path. Destroy the Chocolate pieces by matching Candies next to the Chocolate to make it disappear.
Soda
The goal is to get the Soda up to the top of the board. This is done by "popping" Bottles - when matched or by bursting them with a special Candy. The Bottles then raise the Soda level on the board.
Frosting
Save the Candy Bears! In this game mode, Candy Bears are trapped under the ice. Crush the ice covering the bears to free them. Make sure all of the Bears are saved to complete the level.
Bubble
Match the Soda Bottles with Candies of the same color to raise the Soda levels and bring the Candy Bears to the top. You must get the Candy Bears above the Candy Necklace to complete the level. Tip: Try matching as many bottles as you can, and clear the Candies above the Candy Bears to get them to the top!
Sweet Escape
Free the bear to complete the level. You must try to find the hidden path buried somewhere on the gameboard. Objective is to help the bear escape by matching and clearing candy blockers along the way to the end!
