A guide to Scott Cawthon's free FNaF mashup: office systems, how scoring works, reliable counters for the most common animatronics, beginner presets, Faz-Coins and the Death Coin, challenges, the road to 50/20, and fixing crashes.
Researched September 2026 — current as of patch 1.032 (July 2018), the last gameplay update. Live games change; check the linked sources if something differs.
Status: Ultimate Custom Night released free on Steam on 27 June 2018 and has not had gameplay updates since the 1.03x patches in mid-2018. It is complete and still free to play.
From your office you manage two side doors, two vents, and two air hoses, plus the monitor and tools.
| System | What you do there |
|---|---|
| Cameras | Watch rooms, collect Faz-Coins, deal with camera-based characters |
| Vent system | Set laser traps (vent snares) to block vent crawlers |
| Duct system | Close one of two air ducts, and use the audio lure |
| Tool | Effect | Trade-off |
|---|---|---|
| Power Generator | Slows power drain | Raises noise |
| Silent Ventilation | Lowers noise | The office heats up faster while it runs |
| Heater | Raises temperature | Some characters are repelled by heat |
| Power A/C | Cools the office | Uses power |
| Global Music Box | Keeps music-sensitive characters calm | Uses power |
| Off | Nothing | Saves power |
You pick one tool mode at a time from the office panel, so you are always choosing a trade-off. Also keep an eye on the two Pirate Cove curtains on the cameras; the store page calls them out as a core check.
| Meter | Why it matters |
|---|---|
| Power | Everything uses it; at zero you are defenseless |
| Noise | Attracts noise-sensitive characters |
| Temperature | Too hot and some characters act up; also affects gameplay |
Grouping characters by where they attack makes large rosters manageable. Before a night, sort your roster into these buckets and build a checking routine around them.
| Threat type | What it looks like | Your tool |
|---|---|---|
| Door attackers | Come to the left or right door | Close the matching door at the right moment |
| Vent crawlers | Move through the vent system | Vent snares on the vent monitor |
| Duct crawlers | Travel through the two air ducts | Close a duct, use the audio lure |
| Camera characters | Must be watched or maintained on a specific camera | Regular camera checks |
| Office characters | Appear in the office itself | Mask, clicks, or specific actions |
| Meter characters | React to noise, heat, or power | Tool management |
| Wildcards | Random or disruptive effects | Adapt; save the Death Coin |
A useful habit: every time you pull up the monitor, go through the same order (music box, key cameras, vents, ducts), then drop it and scan the office. A consistent loop means nothing slips through as the roster grows.
Doors are your strongest defense but the most expensive. Close a door only after you hear or see the threat, and open it again as soon as the character leaves. Leaving doors shut "just in case" is the fastest way to run out of power before 6 AM.
Noise rises with active tools like the Power Generator and with some character mechanics. When a noise-sensitive character is in your roster, alternate between Silent Ventilation (quiet) and the A/C (cool, but uses power), since only one tool runs at a time. If both noise and heat matter, prioritize whichever character is more dangerous at your chosen levels.
Every character has a specific counter. These are the ones new players trip over the most, summarized from community play; the character card on the select screen is the authoritative version, so double-check it before a serious run.
| Animatronic | Counter |
|---|---|
| Puppet (Marionette) | Keep her music box wound on its camera |
| Toy Freddy | Watch his game of Five Nights with Mr. Hugs on camera; close the door on his game when the enemy is at it |
| Toy Bonnie / Toy Chica | Put on the Freddy mask when they appear |
| Chica | Keep her fed with music she likes; she gets bored of a song, so check her card for how to change it |
| Nightmarionne | Move your mouse away when it appears |
| Rockstar Freddy | Pay him 5 Faz-Coins or turn on the Heater |
| Rockstar Foxy | His parrot offers deals; click it |
| Phone Guy | Mute the call |
| Helpy | Click him before he blows the air horn |
| Bonnet | Click her nose |
| Lolbit | Type LOL |
| Music Man | Keep the noise low |
| Ballora | Listen for her music and close the door on that side |
| Vent crawlers (e.g. Molten Freddy, Scrap Baby, Afton) | Snare the vent they are in on the vent monitor; check each character's card for which system they use |
| Jack-O-Chica | Keep the temperature low |
| Dee Dee | Randomly adds extra characters to the night |
Some rewards give power-ups such as Frigid (cools the office), 3 Coins (start with coins), and DD Repel (keep Dee Dee away). Check the Prize Counter and challenge menu in your copy for exactly how each is unlocked.
The challenge menu has 16 themed challenges with preset animatronic groups. They are good practice for specific mechanics.
| Preset | Characters | Why |
|---|---|---|
| Learn systems | Puppet, Toy Freddy, Phone Guy, Chica | Simple mechanics, teaches monitor use |
| Office management | Toy Bonnie, Toy Chica, Rockstar Freddy, Helpy | Mask, coins, clicks |
| Vent control | Molten Freddy, Afton, Scrap Baby | Vent snares |
| Audio | Ballora, Music Man | Listening |
Raise levels once each preset feels easy.
| Step | Target | What you are learning |
|---|---|---|
| 1 | Each beginner preset at low levels | One mechanic at a time |
| 2 | Two presets combined, low levels | Multitasking between monitor and office |
| 3 | 15-20 characters at mid levels | Routines, power budgeting |
| 4 | Challenges from the challenge menu | Themed stress tests |
| 5 | 30+ characters, gradually raising levels | Endurance and prioritization |
| 6 | 8,000+ points (bronze statue) | High-level consistency |
| 7 | 9,000+ points (silver statue) | Near-max play |
| 8 | 50/20 (gold statue) | The ultimate test |
When a run fails, note which character ended it. Nearly every loss comes from one or two characters you are not handling consistently. Drop everything else to low levels and drill those until they feel automatic.
Patch 1.025 added an option to disable visual effects: on the character select menu, un-check the "visual effects" box. Patch 1.031 adjusted a visual effect that may improve performance. If the game stutters on an older PC, try the visual effects toggle first.
System requirements are tiny (the Steam page lists a 2 GHz CPU, 2 GB of RAM, a 1 GB graphics card and 500 MB of storage). Note that the page still lists Windows XP through 10, but the Steam client itself has only supported Windows 10 and later since 1 January 2024.
The game got a quick run of balance and bug-fix patches in the weeks after launch, then stopped. The notes that matter for strategy:
| Patch | What changed |
|---|---|
| 1.024 to 1.030 | Fixes for vent-crawler behaviour, inconsistent Ballora attack timing, and assorted animatronic bugs |
| 1.025 | Option to turn off visual effects |
| 1.031 | Bonnet no longer gets stuck on screen or repeats nights incorrectly; Toy Chica mirror glitch and Lefty fixed; 50/20 time tracking corrected; Toy Chica and Toy Bonnie appearance rates rebalanced (fewer Toy Bonnie spawns); the block sound effect is louder; a visual effect tuned for performance |
| 1.032 | Menu statues for high scores: bronze Freddy (8,000+), silver (9,000+) and gold (50/20) |
If an old video shows a character behaving differently, it may predate these fixes.
In August 2018, Scott Cawthon noted crash reports linked to anti-virus programs flagging the game or its save files. If the game crashes:
Is Ultimate Custom Night free? Yes. It is free on Steam.
How many characters are there? 50, from seven FNaF games.
What's the maximum score? 10,000 points (all 50 characters at level 20).
What is 50/20? All 50 animatronics at level 20 — the hardest possible night.
Why does my game crash? Often anti-virus software; allow the game in your anti-virus.
Is there a story? There are unlockable cutscenes and voice acting that hint at the lore.
How do I turn off visual effects? On the character select menu, un-check the "visual effects" box (added in patch 1.025).
What do the statues on the menu mean? Patch 1.032 added a bronze Freddy statue for 8,000+ points, silver for 9,000+, and gold for beating 50/20.
