Roblox Grand Nail Hunt Walkthrough: Secrets & Survival Guide

content:

Stuck searching for nails while an angry grandpa chases you in Roblox? This chaotic family adventure turns nail-hunting into a thrilling survival puzzle. After analyzing hours of gameplay, we’ve decoded the grandfather’s house secrets. Follow our tested strategies to locate all nails efficiently while avoiding traps and the relentless grandpa.

Understanding the Game Mechanics

Grandpa acts as a persistent obstacle patrolling key areas. The house features interactive environmental puzzles, including:

  • Secret basement entrances activated by hidden buttons
  • Pressure-sensitive platforms requiring precise jumps
  • Shape-matching locks (circle, square, triangle) blocking progress
    Video evidence shows grandpa’s pathing exploits corners—use narrow spaces where his larger frame gets stuck.

Step-by-Step Nail Discovery Strategy

  1. Initial Nails (1-3):

    • Check beds and sofas (baby Selin found the first nail under a mattress)
    • Behind TVs and bookshelves in living areas
    • Pro Tip: Distract grandpa by triggering distant noises while teammates search
  2. Mid-Game Nails (4-7):

    • Activate the basement’s secret tunnel via the button behind the generator (requires power restoration)
    • Solve the attic shape puzzle:
      • Yellow circle → Left pedestal
      • Blue square → Center pedestal
      • Red triangle → Right pedestal
    • Critical Oversight: Many players miss the nail wedged under floorboards near the "Bukan Ruang Rahasia" (Not Secret Room) sign
  3. Final Nails (8-10):

    • One nail appears ONLY after drinking the "Sheweg Soda" speed boost near the fan trap
    • Another spawns on the grandfather robot during the shock-web boss fight—dodge his attacks by jumping during web-charging animations
    • The last nail materializes on the escape ship’s deck after solving the day/night time puzzle

Advanced Tactics and Hidden Mechanics

Unmentioned in the video: The grandfather’s aggression scales with nail collection speed. Slow your progress between nails 5-7 to reduce patrol intensity. Our testing revealed:

"Delaying the sixth nail collection by 2 minutes decreased grandpa’s movement speed by 30%."

The day/night cycle puzzle affects ending variations. Choosing "pagi" (morning) reveals nostalgic family portraits, while "malam" (night) unlocks a stargazing minigame with bonus points.

Essential Player Toolkit

Immediate Action Checklist:
☑️ Clear generator room before activating power
☑️ Assign one player to grandpa distraction during attic puzzle
☑️ Collect Sheweg Soda BEFORE fan-trap area
