Level 688

Difficulty

 * Clearing the cake bomb is the major issue at the start, since the candy bombs have 9 moves before detonation. Moreover, it has been shifted one row down, increasing the difficulty of clearing it even further.
 * There are double jellies underneath the cake bomb.
 * Once the cake bomb is gone, clearing the double isolated jellies is the major issue, even at a whopping 50 moves.
 * Now that the level has five colours, it is even more difficult than before to destroy the cake bomb and the jellies.
 * On web version, candy bombs actually explode before the cake bomb goes off, which means the game is still lost if any of the bombs reach zero, even with the cake bomb cleared. This is not an issue on mobile version however.
 * The jellies are worth 24,000 points. Hence, an additional 46,000 points is required for one star.

Strategy

 * Clear the cake bomb quickly.
 * If you are playing on mobile and find out that you cannot remove at least one cake slice on your first move, you can reset the board without losing a life, provided that you have not made your first move.
 * Once the cake bomb is gone, create special candies or their respective combinations to clear the isolated jellies. Colour bombs are helpful in this one.

Trivia

 * The level board is shaped like an alien, a reference to Space Invaders.
