Ninja Factor top tip:

Slashing factors of “2” can be really fun since they are the easiest to remember of them all.

Remember this easy tips to quickly increase your score with four digit combos:
- A combo is a factor of “2” when the last digit is an even number (0, 2, 4, 6, or 8).
- When forming a combo try to slash the “2” last.

In simple words: “Slash the biggest number first and try to cut a 2 or a 0 last”

Easy as pie right ;)
