Hi, sorry for the ongoing interruption,  
could anyone help me with the level gem by gem? Im really stuck  
here is my code:

```python
# Connect gems to a linked list to open the door.

# Use that gems a base for the list.
baseGem = hero.findByType("root-gem")[0]
# Those gems are not linked yet.
freeGems = hero.findByType("gem")

# Use the property "next" to link elements to the list.
# Append an element before the base gem.
freeGems[0].next = baseGem
# And one more at the new head of the list:

# Next add more gems at the end.
baseGem.next = freeGems[2]
# Add two more gems one by one:

while True:
    if hero.isPathClear(hero.pos, {"x": 76, "y": 34}):
        hero.moveXY(76, 34)

```

Thanks,  
Mumbo\_6

You did not change the base code I see. Would you like for me to explain to you the logic of this level?

Ok then.

> [@Mumbo\_6](#):
>
> `baseGem.next = freeGems[2]`

This means that we have the elements in this order:  
baseGem, freeGems.  
You should have this order in order to complete the level:  
freeGems[1], freeGems[0], baseGem, freeGems[2], freeGems[3], freeGems[4].  
Do you understand?
