**TLDR -** Readers guessing your plot twist doesn't have to mean it's ruined, there are ways to make it satisfying

linksassin's answer is good, but I'll offer an alternate idea :

**Anticipated plot twists can work if they're executed well**

Take the famous Star Wars example. The twist that Darth Vader is Luke's father isn't a twist for present day first-time viewers. It didn't make it any less satisfying for me, because

 1. Watching the movies with the twist in mind **added a layer of depth to the characters' actions** (Obi-Wan says Vader killed Luke's father - in a way, I guess he did. Knowing that Obi-Wan and Vader used to be friends makes Obi-Wan's death even sadder) 

 2. I knew what would happen, but **I didn't know *how* it would happen**. The characters' reactions to the twist were enjoyable and  consistent with their development so far.

Another well-done plot twist was in *Gravity Falls* -
>! The reveal that Stan Pines had a long-lost twin

By the time the reveal episode aired, most of the fans had come up with this theory and had lots of evidence to back up their claims.

What made it so satisfying was - 
 
1. The execution - it was a tense, emotional scene, and although the fans had guessed the main idea, there were **a lot of additional details that were new** (and twisty in their own rights)

2. This depends on the kind of story you're writing, I suppose, but the work that fans put in to come up with this theory was... intense, is one word for it. The creator dropped some **well-hidden hints and foreshadowing**, but also lampshaded the idea in some other episodes (to try to throw fans off track? I don't know)

Those are two plot twists that people saw coming, but still remain enjoyable. 

An infamous example of an unexpected and widely disliked plot twist was the ending of Game Of Thrones - 

>! Danaerys's descent into madness was barely foreshadowed, and more importantly, other things which *were* foreshadowed were not fulfilled. 

Once you make a contract with the reader, you have to fulfill it, or risk leaving the readers feeling cheated. 

If you have a prophecy, for example, you can either play it straight and fulfill it in the expected manner, or twist the words for some surprises (*Percy Jackson* does this quite often). 

What you *can't* * do is, in your penultimate or climax chapter, have your MC say 'Screw this prophecy, lets go do our own thing' - at least, you can't do it without previously establishing that your MC doesn't believe in prophecy, is tired of being pushed around by oracles, etc. If your MC has been totally fine with the prophecy so far, then this isn't a plot twist, it's an inconsistency. 

IMO, a predictable yet satisfying plot twist is better than a 'smart' or bizarre one (like you said in your question)

*'Can't' in writing is subjective - it usually means 'you shouldn't do this unless you're very confident in your work because usually when this is done it doesn't turn out well'
