In the grand finale of the One Night at Flumpty's trilogy, Flumpty Bumpty has a new set of rules and a new frozen lair. You must manage your body temperature with the heater while using your limited camera flash to repel attackers. Featuring more monsters, multiple endings, and a secret 'Flumpty Night,' this entry is the most feature-rich and atmospheric of the series. Can you survive the cold and solve Flumpty's final puzzle?

Dinsun Expert Review

Our Expert Score

88/100

One Night at Flumpty's 3 is the definitive finale to the trilogy, and it goes out with a cold, terrifying bang. The introduction of the 'Camera Flash' and the 'Heater' mechanics adds a layer of resource management that feels fresh and incredibly stressful. Setting the game in a frozen environment allows for new environmental storytelling and a much darker color palette that heightens the dread.

What makes this entry special is the 'Intermission' segments and the multiple endings. The puzzles within the cameras are more intricate, and the AI of the new monsters is far more aggressive. The developer has truly mastered the 'point-and-click' horror loop here, providing a definitive end to Flumpty's story that is both narratively satisfying and mechanically brutal. It is a must-play for horror fans who appreciate high-quality 2D animation and clever gameplay design. It’s hard to believe this started as a fan project; the quality here rivals the best indie horror titles on the market.

This is how you end it wow! The beaver and the owl are merged, the Redman gets a better function with the Thermometer, and Golden Flumpty actually kind of does something for a change. It’s a great balance trying to keep yourself warm, making sure you don’t flash grunkfuss and making sure you don’t forget about one of the characters. But the best thing about this game is Flumpty Night. Holy crap it’s so cool. After Flumpty’s friends fail him again, he’s had enough and takes things into his own hands by brutally murdering his friends and showing you his true power. “I can transcend time and space” as he said in the first game and he wasn’t lying. Setting the time back to 12am and being in multiple places at the same time. It’s absolute chaos and I love it. No more funny stuff he’s serious this time and the music goes so well with it. He continuously multiplies himself and adds multiple mechanics (some being from the past games like the exposure meter) as the night goes on, just trying to mess with you and stress you out as much as possible. And then the music changes to Eleggtroswing which 1st off is a banger but also just stresses you out even more. And as if it couldn’t get even more chaotic, he starts messing with the time, the thermometer, the amount of pictures it’s absolutely insane how he shows you how crazy he really is. Without a doubt the best of the trilogy and one of the absolute best FNaF fan games out there!

I LOVE THIS GAME!!!!!!!!!!!

You see I’m a big ONAF fan. I when I found out that there was Third game I could not wait! And let me tell you it’s worth $1:99! I have beaten the game yet, but it’s still lot’s of fun! I only have one problem tho… you see there’s this clown and if you take his picture he kills you. But birthday boy blame you need to take his picture or he will kill you. So at first it seems easy one don’t take his picture another do take his picture. But sometimes both appear in your office. So if take a picture birthday boy blame runs a way and doesn’t kill you, but clown kills you. And if you don’t take a picture the clown won’t kill you, but birthday boy blame will. You see the problem you die either way. So that’s just my opinion. But if you ask me if you should play it I’ll say check it out if you’re interested. This is amazing and I’ll a lot even if not Halloween!

Pretty great game

I’m the biggest Onaf fan and I can say this is one of the best fnaf fan games however it’s not perfect night one is pretty meh birthday boy blam is fine along with red man and the beavowl also the beavowl is the best character to be in this game grunkfuss is ok he’s not bad but pretty annoying eyesaur is the worst character in this night and golden Flumpty is ok he has good hiding spots the fake 6 am is amazing along with Flumpty night I cannot believe that was in this game it was scary but amazing and the music is good but eleggoswing is a bop and fire I can listen to it for hours hard boiled mode is a nice way final night and the ending is a great ending however the best part of this game is Kevin jr.

Great but…

So this game is super bonkers. You have the normal night and then the flumpty night. The flumpty night is really hard for me bc I keep forgetting about characters and the song that plays when you’re about to beat flumpty night. I love it! But there is one problem though. How come I can’t play the song like the people do on pc? Like I can’t hear the song playing. Can you make the song go on iPad and iPhone? I would really appreciate it. Overall, awesome game!

This game is fun but it would be more fun if I can actually play it

I re-download it and download this game for like five times and it didn’t let me and I just kept kicking me out one time I actually got to play the game but it just kicked me out the time I got into the office I didn’t even get to see any characters know nothing you should really fix this or I’m never gonna play your games again I really hope you can see this developers and the worst part about it is that you’re like oh cool I knew one night at Flumpty’s game but all you do is enter the game see the company who made it and then you just get kicked out of it so I can’t play it I really hope that you can patch us so I can actually play the game or I will tell all of my friends to not like these games and I will never play it again OK?

One bug
Mon May 27 2024 GAMERZTOWN2638393929102038365

So this is a great game but whenever it’s 4am and when the Eyesaur comes out in the hallway, I die whenever I take the second picture of him because Grunkfuss is always there, This happened to me four tones on a row, So I guess I have bad luck or it’s just a bug, So what I am saying is this is basically impossible for me, Overall great game!

This game is the best
