[emoji][emoji]the right one--没有意思 ： boring ; meaningless

before 有，the Negative Word 没 is the only one should be used

不有意思 is actually the same as 没有意思. However, 不有意思 is often used as casual way. When you say "没" as "不", it sounds cute. All in all, the difference between 不有意思 and 没有意思 is like the difference between Yeah( you can also say it in exaggerate way) and yes.

Thanks so much, could you please tell me, which one is correct? 有点儿意思 一点儿意思

没有意思
