31 questions. Free, and just for fun.
SBTI is a playful internet personality quiz. Its 31 questions score you on 15 traits across five areas (self, emotions, attitude, action and social life), then find which of 27 types you're closest to. It's made for laughing at yourself and comparing with friends.
BaZi mode looks at the Ten Gods in your birth chart, converts them into the same 15 traits, and matches you to an SBTI type. Use it when you don't feel like answering questions, or compare it with your quiz result.
SBTI is a for-fun test. It's good for thinking about yourself and chatting with friends, not for making career or relationship decisions.
There are 27: 25 standard types plus 2 hidden ones. If no standard type matches you well enough (below 60%), you get HHHH. Picking a certain drinking answer unlocks DRUNK.
MBTI sorts people into 16 types using four pairs of preferences. SBTI scores 15 traits across five areas and matches you to one of 27 types, with an internet-meme sense of humor. It's built for fun and self-mockery.
Yes, it's free with no signup. Answer the 31 questions or use BaZi mode with your birth date. Either way you see the full result: your type, your 15 trait scores and your 5 closest types.
