### Step 1: Understand the Level Requirements
– **Objective:** Bring down all ingredients and reach 142,000 points to complete the level.
– **Moves:** You have only 20 moves.
– **Ingredients:** There are 3 ingredients in this level.

### Step 2: Plan Your Strategy
– **Difficulty:** This level has a hard difficulty, so planning is crucial.
– **Focus Areas:** Play near to gums and blockers. These elements can be used to your advantage by clearing them to free up space and create opportunities for matches.

### Step 3: Initial Moves
1. **Clear Gums and Blockers:**
– Start by clearing any gums or blockers that are easily accessible. This will help in creating space and making it easier to move the ingredients.

2. **Create Striped Candy:**
– Focus on creating striped candies (vertical or horizontal) as they are powerful for clearing multiple candies at once and moving ingredients.

3. **Move Ingredients:**

– Combine striped candies with other special candies like color bombs or wrapped candies to maximize your points and clear the board efficiently.

### Step 5: Manage Your Moves
1. **Prioritize Ingredient Movement:**
– Always prioritize moving the ingredients towards the bottom of the board. Use striped candies to push them down.

2. **Clear Remaining Gums and Blockers:**
– Once the ingredients are in place, focus on clearing any remaining gums and blockers to free up space and create more opportunities for matches.

3. **Maximize Points:**
– Make sure to clear as many candies as possible in each move to maximize your points.

### Step 6: Final Moves
1. **Clear Remaining Ingredients:**
– In your final moves, focus on clearing any remaining ingredients that are still on the board.

2. **Maximize Final Points:**
– Use any remaining special candies or striped candies to clear as many candies as possible and reach the required 142,000 points.

### Additional Tips
