Here is a guide about the Pockie Nijia, How to Unlock More Skill Slots in Pockie Nijia. Thank Anixian who posted it on urgametips.com. If you have any problem about it, just check below:

Normally, players can only use up to 6 free skill slots, but with the new chapter patch released for the online browser game Pockie Ninja, players can now use items to open 4 more skill slots besides the 6 original ones.

Important Note:
The guide below can also be applied to Pockie Ninja's (PN II Upgrade). All Main Functions can still be found and are still working.

The Rules
- Skill slots requires a number of Kakashi's Notebook and will expire after the validity period.
- When the next skill slot is opened, the previous one will exist forever and will never expire!
- To open the succeeding skill slots, you have to open the preceding skill slots first.

1st Skill Slot
- Requires 5 Kakashi's Notebook.
- Validity Period: 10 Days

2nd Skill Slot
- Requires 25 Kakashi's Notebook.
- Validity Period: 20 Days

3rd Skill Slot
- Requires 125 Kakashi's Notebook.
- Validity Period: 30 Days

4th Skill Slot
- Requires 300 Kakashi's Notebook.

Note: Skill placed in different skill slots will directly impact the release and effect of the skill!
