Cut the Rope Level 423 — Underground Box Walkthrough (3 Stars)
Level 423★★★★★
Guide by LevelWalks
If Level 422 of Cut the Rope felt routine, Level 423 is the kind that breaks the pattern. The devs schedule these on purpose — usually right where players start solving on autopilot.
## Cut the Rope — Underground Box, Level 23
**Box:** Underground Box | **Level:** 423 (Underground Box #23)
## Walkthrough
This level uses anti-gravity, bubbles, rocket boosters, air cushions and time reversals. The candy starts from the top and Om Nom is waiting at the bottom.
### Step-by-Step Solution
1. **First, observe the layout.** Look at where the candy hangs and trace a path to Om Nom. Note every rope, bubble, and obstacle.
2. **Cut the first rope** — the one holding the candy closest to the top. This drops the candy toward the first star.
3. **Use the anti-gravity** to redirect the candy toward the second star. Timing is important here — wait until the candy swings to its peak before activating.
4. **Collect the final star** by popping the bubble at the right moment.
5. **Guide the candy to Om Nom.** If you miss a star, the candy should still reach Om Nom — just replay for a perfect score.
### Getting All 3 Stars
- Star 1: Drops naturally when you cut the first rope.
- Star 2: Requires precise timing with the anti-gravity.
- Star 3: The hardest one — you need to use the bubble to float up before the candy falls past it.
## Tips for This Level
The Underground Box introduces anti-gravity which add a new dimension to your puzzle-solving. Don't rush — watch the candy's momentum and plan two moves ahead.
## Why This Level Is Tricky
Maximum difficulty Cut the Rope levels are precision instruments — every element is placed to create exactly one three-star solution with extremely tight timing requirements. The margin for error shrinks to the point where understanding the physics equations behind the game engine provides a genuine advantage.
## Common Mistakes
Players frequently make these errors on Level 423:
- Rushing to feed Om Nom and skipping the hardest star — getting 2 stars is easy, but the third requires a specific trick.
- Cutting a rope when the candy is at the bottom of its swing instead of the top, resulting in a shorter arc.
- Ignoring the visual hint lines that some levels display briefly at the start, showing the intended cut order.
Tips
- Cut ropes in order from top to bottom for the most control over candy movement.
- In the Underground Box, anti-gravity are key — learn their timing patterns.
- You don't need all 3 stars to progress, but replay levels later for a perfect score.
