Fight Your Zombie Machine Tier List
Which plot machines deserve coins first — farms, synthesizers, and starter automation.
Machines automate the brain pipeline in Fight Your Zombie. Simple Bricks Zombies gates them behind the same incremental curve as brain tanks: starter tools first, advanced farms mid-game, synthesizers when rarities matter for prestige. This tier list ranks machine categories and purchase timing S/A/B/C based on coins and brains per hour — not visual flair.
Pair with Machines guide, Upgrade Order, and Machine tier hub context. Exact in-game names may shift after updates; tiers describe roles.
Tier criteria
- S — Core automation; buy immediately when unlocked if zombie/tank baselines exist
- A — Strong multipliers; next purchases after S-tier
- B — Event-dependent or luxury; buy with spare coins
- C — Trap or cosmetic until late Void layers
S tier machines
Auto-collect starter unit
The first machine that pulls brains from tanks without manual clicks. S tier because it prevents AFK overflow cap — especially with offline growth. Buy right after first zombie upgrade wave (Getting Started).
Primary advanced farm
The first advanced farm that buffs multiple tank slots or doubles Normal output. Defines mid-game brain salary. Delay only if zombie multipliers are critically underleveled.
Core synthesizer (mid unlock)
First synthesizer that converts Normal surplus into Shiny value or boosts Rainbow proc. S tier once you regularly overflow Normal brains after feeding. Synergizes with Lucky Blocks during 2x luck.
A tier machines
Secondary farm chain upgrade
Next farm tier expanding slot coverage or offline capacity. A tier — essential but after primary S farm and tank capacity upgrades.
Feed routing / conveyor tools
Machines that speed feed loops between storage and zombie. A tier for active players who fight long sessions; B tier if you log in briefly and rely on offline tanks.
Advanced synthesizer tier two
Pushes Rainbow output for Void pushes. A tier before luxury weapons.
Super Machine pass synergy nodes
In-game machine tiers that multiply if you own Super Machine (999 R$) — see Game Passes. Rank A tier when pass owned; skip until then.
B tier machines
Cosmetic plot decorations with minor buffs
Small stat bumps tied to visuals. Buy during coin floods or when completionists prestiging.
Event-only machines
Limited banners from Updates — B tier during event, C tier after expiry unless permanents.
Duplicate farm on secondary plot corner
Low coverage layouts — upgrade primary farm first per Upgrade Priority.
Luck-only machines outside 2x weekends
Underperform without Updates luck flag.
C tier machines (early game traps)
Weapon-linked machines before zombie stats
Any machine package tied to sword DPS while fights still pay poorly — classic trap breaking upgrade order.
Remote lucky block opener gadget
Saves walking during events but wastes keys at normal odds — manual hoard strategy wins (Lucky Blocks guide).
Pre-prestige luxury synthesizer
Top-tier synthesizer bought hours before reset without using output — finish Prestige guide math first.

Pass and script notes
Super Machine pass elevates farm tiers half a letter when owned. Scripts advertising auto farm plot zombie bypass this tier list and risk bans — Scripts Safety. Codes do not unlock machines — Codes Hub confirms none exist.

Buy S farms before shiny swords. The tier list exists because that sentence is true every patch.
