FNAF Ultimate Custom Night - Play Free Online Unblocked
The ultimate FNAF challenge with 50 animatronics. Free to play, no download required.
🎮What is FNAF Ultimate Custom Night?
Five Nights at Freddy's: Ultimate Custom Night (UCN) is the ultimate FNAF experience, developed by Scott Cawthon and released on June 27, 2018. This standalone game brings together 50 selectable animatronic characters from across the entire FNAF franchise into one intense survival experience.
Unlike other FNAF games, UCN is completely free to play and focuses purely on gameplay challenge rather than story progression. You can customize the difficulty of each animatronic from 0 to 20, creating billions of possible combinations. The infamous 50/20 mode — setting all 50 animatronics to maximum difficulty — is considered one of gaming's greatest challenges.
🤖All 50 Animatronics
UCN features characters from FNAF 1 through FNAF 6, each with unique mechanics and behaviors:
🐻 FNAF 1 Gang
Freddy, Bonnie, Chica, Foxy, Golden Freddy — The originals return with enhanced AI. Freddy approaches when you're not watching, Foxy charges from Pirate Cove, and Golden Freddy appears when you least expect it.
🎀 Toy Animatronics
Toy Freddy, Toy Bonnie, Toy Chica, Mangle, BB, JJ, The Puppet — Toy Freddy plays a game within the game. Fail his game, and he kills you. Mangle climbs through vents and attacks from above.
💀 Withered Animatronics
Withered Bonnie, Withered Chica, Withered Freddy, Withered Foxy — Damaged but deadly. Each requires different strategies to survive. Withered Bonnie disables your camera map.
👻 Phantom Animatronics
Phantom Mangle, Phantom Freddy, Phantom BB — They can't kill you directly but cause distractions, jumpscare effects, and disable your equipment at critical moments.
🎃 Nightmare Animatronics
Nightmare Freddy, Nightmare Bonnie, Nightmare Fredbear, Nightmare, Nightmarionne, Nightmare BB — The terrifying nightmare versions. Nightmare Freddy spawns Freddles that must be flashed away.
🎪 Funtime Animatronics
Circus Baby, Ballora, Funtime Freddy, Funtime Foxy, Ennard — From Sister Location. Funtime Foxy has a timer that counts down to an unavoidable attack unless you watch the show.
🔥 Rockstar Animatronics
Rockstar Freddy, Rockstar Bonnie, Rockstar Chica, Rockstar Foxy, Lefty — From FNAF 6. Rockstar Freddy demands coins or he attacks. Rockstar Foxy can help or hurt you randomly.
🗑️ Mediocre Melodies & Others
Mr. Hippo, Happy Frog, Pigpatch, Nedd Bear, Orville, Trash and the Gang, Helpy, Phone Guy — Even the minor characters get their moment. Mr. Hippo's death screen features endless rambling stories.
⚠️ Special Threats
Old Man Consequences, Dee Dee, XOR, Fredbear, Spring Bonnie — Dee Dee can randomly add extra animatronics to your night, including the secret XOR who adds multiple threats at once. Fredbear is one of the most dangerous, requiring precise timing to survive.
🎯Office Mechanics & Controls
Your office has multiple defense systems that must be managed simultaneously:
🚪 Two Doors
Close the left and right doors to block animatronics. But be careful — keeping doors closed drains your power quickly. Some animatronics like Nightmare Bonnie and Nightmare Mangle attack through the side vents instead.
🌀 Two Air Vents
The front vent (above you) and side vent require different defenses. Close the front vent to block characters like Mangle and Withered Chica. Use the vent snare for the side vent to catch Springtrap and others.
📹 Camera System
Monitor the cameras to track animatronic movements, reset the ventilation, turn on the heater, and wind the music box. But while you're in the cameras, you can't see what's approaching your office.
🎵 Music Box
The Puppet's music box must be wound regularly. If it stops, The Puppet will attack and there's no way to stop it. Find CAM 07 and wind it before it's too late.
🔦 Flashlight & Power
Use the flashlight to check hallways and ward off certain animatronics like Nightmare Freddy's Freddles. Power A/C and Global Music Box drain power — manage it carefully or face blackout attacks.
🏆Preset Challenges
UCN features 16 preset challenges with increasing difficulty:
💡Survival Tips for 50/20 Mode
- 1.
Master the camera pattern: Develop a consistent routine — check Foxy's camera, wind the music box, monitor vents. Timing is everything in 50/20 mode.
- 2.
Use the Power A/C wisely: Only turn it on when temperature gets critical. Overusing it drains power fast and leaves you vulnerable to Freddy.
- 3.
Learn audio cues: Many animatronics have unique sounds. Rockstar Bonnie plays guitar, Ballora hums, Nightmare Fredbear laughs. Use audio to track threats without cameras.
- 4.
Pray Dee Dee is merciful: Dee Dee can randomly add extra animatronics. Use the Death Coin power-up (if you have it) to eliminate one threat, but save it for the worst situations.
- 5.
Don't panic: When multiple threats converge, stay calm and follow your routine. Panic leads to mistakes, and mistakes lead to jumpscares.
🎬Cutscenes & Lore
Completing challenges unlocks special cutscenes that expand FNAF lore:
🐻 The One You Should Not Have Killed
Multiple cutscenes show a mysterious entity tormenting the player. Many theorize this is Golden Freddy/Cassidy keeping William Afton trapped in a personal hell — unable to die, forever hunted by his victims.
🎣 Old Man Consequences
A secret minigame featuring a fishing bear. The cryptic message "Leave the demon to his demons. Rest your own soul. There is nothing else" hints at the game's deeper meaning about letting go.
🔥 Hell Theory
Popular fan theory suggests UCN is William Afton's personal purgatory — eternally tormented by the animatronics he created and the children he murdered. The game never ends; the suffering is eternal.
