Classic Chuzzle is one of the five gamemodes in Chuzzle. In this game mode, there are two difficulty modes with Casual and Expert. When the player creates a new profile in Chuzzle, this mode will automatically be played in Casual difficulty.
The goal for the player is to match three or more Chuzzles in order to fill in the flusk. After the flusk is completely filled, the player advances to the next level with additional points depending on the level he/she is playing on (for example, completing level 11 will give the player 11,000 points). Depending on the difficulty, Puzzle Locks will randomly appear after a few levels in Casual difficulty or at any time in Expert difficulty, making the game mode harder. As the level increases, the flusk requires more Chuzzles to be matched in order to fill it and the frequency of Puzzle Locks increases slowly in Casual difficulty or at a increased rate in Expert difficulty.
If no more possible moves can be made, a Scramble option will appear in order to scramble the board as well as removing all Puzzle Locks from Chuzzles. This will use up a Scramble however and the player is given two Scrambles at the start of the game, with up to three additional Scrambles if the player manages to score certain amounts of points. The game ends if player ran out of possible moves and Scrambles.
