What is best to use when summoning- single or multi? I have read about people saying single is best

If you have enough experience in single summon, you can try for multi summon. I got many 6* characters from free multi summon. If you perform well in multi summon,you can get 3 or 4, 6* characters.

Yeah singles are better

Single summons are just better you have might have higher chances to summon more and get gold more because you have higher chances of summoning.

Single is better

I think single summons are easily better because they cost around the same as a normal multi for 10 characters and you might have higher chance of getting gold on single. Singles you can do it everyday when you get 5 ninja pearls and multi just gives you so many silver and bornze.

In Multi i always get up to 6 5stars and its easy to farm stones so just make Multis

In Naruto Blazing, no difference in summon rate between single and multi is confirmed yet. I would say you can save time by doing multi.
