• Danger: Appears in later rounds; only elite setups survive
• Understanding these monsters is the first step. Now let’s talk about how to beat each one.

How to Beat the Red Ghost

• Best Turret: Machine Gun Turret
• Strategy: Place turrets at room entrances and near your bed
• Trap Support: Use slow traps and walls to delay its movement
• Tip: Upgrade your door early speed is its biggest threat

How to Beat the Blue Ghost

• Best Turret: Laser Turret or Motion Detector Turret
• Strategy: Spread turrets evenly across the map
• Trap Support: Use motion-sensing traps
• Tip: Watch movement paths blue ghosts sneak in from uncommon angles

How to Beat the Black Ghost

• Best Turret: Rocket Launcher or Cannon Turret
• Strategy: Build turrets inside the room, not just outside walls
• Trap Support: Traps don’t work well focus on brute firepower
• Tip: Reinforce your inner room with multiple turrets and thick doors

How to Beat the Electric Demon

• Best Turret: Remote Laser or Flame Thrower Turret
• Strategy: Space out your turrets so one being disabled doesn’t shut down all
• Trap Support: Stun traps or shock walls
• Tip: Don’t cluster machines—keep your defenses diversified

How to Beat the Boss Ghost

• Best Turret: Maxed Laser + Rocket Combo
• Strategy: Full upgrade of walls, doors, turrets, and bed
• Trap Support: Use combo traps: stun + slow
• Tip: You need elite defense + backup room to survive boss ghost waves

Timing is just as important as defense types. Follow this upgrade timeline for best results:

Early Game (Waves 1–3)

• Focus on money generators + bed upgrades
• Start building basic turrets and walls

Mid Game (Waves 4–6)

• Upgrade doors + turret damage
• Research trap technology + turret range

Late Game (Waves 7+)

• Max out your bed, turret combos, and inner room defense
• Build a second secure room for retreat in case the main one breaks

Upgrade Order (General Rule)

1. Bed → Generator → Door → Turrets → Research → Walls → Traps
2. Always have 2–3 turrets upgraded before ghosts increase in power
3. By wave 5, all turrets should be at mid-level at least

Using this timing strategy ensures you’re never caught off-guard, no matter what monster is coming.
