Unlocking Every Secret: The Ultimate LEGO Harry Potter 5, 7 Years Walkthrough for 100% Completion

Stepping back into the wizarding world through the lens of Traveller’s Tales’ signature brick-building adventure is a nostalgic thrill. However, as the narrative darkens in the later books, so too does the complexity of the game’s puzzles. If you find yourself endlessly wandering the shifting halls of Hogwarts, staring at a locked vault you cannot open, or missing a single Gold Brick to finish your collection, you are not alone. Getting stuck at 95% is a rite of passage for many completionist gamers.

To overcome these hurdles, you need a reliable Harry Potter 5, 7 Years Walkthrough to guide you through the intricate hub worlds, complex character abilities, and hidden collectibles. As a veteran of LEGO games who has painstakingly achieved 100% completion across multiple platforms, I can assure you that finishing this game requires more than just a quick wand flick. This comprehensive guide serves as your digital Marauder’s Map. By the end of this guide, you will have the strategies necessary to unlock every Red Brick, rescue every Student in Peril, and claim the coveted 100% completion trophy.

II. The “Golden Rule” of LEGO Harry Potter: Strategy for 100%

Before diving into specific levels, it is crucial to understand the foundational rhythm of LEGO Harry Potter: Years 5-7. The game is specifically designed to prevent you from collecting everything right away.

Don’t Stress the First Pass

Many new players waste hours trying to reach areas locked behind red sparkles (Dark Magic) or heavy orange handles (Super Strength) during their initial playthrough. Do not do this. Your first run through a level is strictly about survival, learning mechanics, and enjoying the story. The game purposefully withholds characters with essential abilities until much later.

The Two-Step Process

To efficiently hit 100%, you must master the two-step cycle:

1. Story Mode: Play through Years 5 through 7 linearly. Focus on gathering enough studs to achieve “True Wizard” status in each level (which grants a Gold Brick) and unlock essential spells. Do not worry about missed items.

2. Free Play: Once the story is complete, return to the levels and the massive Hogwarts hub. Now equipped with a massive roster of unlocked characters, you can swap between them on the fly to solve puzzles you previously had to abandon.

Priority One: Unlock a Dark Wizard and a Strong Character

To conquer Free Play, your immediate priority after finishing the story is purchasing a Dark Magic user. Bellatrix Lestrange (unlocked in Year 7) or Tom Riddle are fantastic choices. You will also need a character with Super Strength, such as Hagrid or Fenrir Greyback, to pull those stubborn orange handles. Once you have these two character archetypes in your roster, the entire game opens up.

III. Comprehensive Story Walkthrough: Years 5, 6, and 7

The narrative spans four distinct films, each introducing unique spells and environmental mechanics that you must master.

Year 5 – The Order of the Phoenix

Year 5 introduces a slightly more rebellious tone, requiring you to recruit Dumbledore’s Army while dodging the tyrannical Professor Umbridge.

• Key Levels: Dumbledore’s Army, Focus!, and The Department of Mysteries.

• Essential Spell – Focus: Taught by Professor Snape during Occlumency lessons, the Focus spell is vital. Whenever you see a character with a white, cloudy thought bubble over their head, use Focus. You will enter their mind to solve a mini-puzzle, which often yields key items to progress or hidden collectibles.

• Expert Tip: The Hall of Prophecies in the Department of Mysteries is notorious for being chaotic. Keep moving, utilize the interactive cover, and let your AI companion distract the Death Eaters while you solve the environmental puzzles.

Year 6 – The Half-Blood Prince

This year balances the mundane (Potions class) with the terrifying (Voldemort’s backstory).

• Key Levels: A Giant Virtuoso, Love is in the Air, and The Cave.

• Essential Spell – Aguamenti: The water-making spell is your most used utility this year. You will use it to extinguish magical fires blocking your path, fill massive glass tanks to raise floating platforms, and water magical plants to create climbable vines.

• Expert Tip: In The Cave, when defending Dumbledore from the Inferi, do not rely on standard combat spells. Use the environment—specifically the fire-based puzzles—to keep the undead at bay.

Year 7 (Part 1) – The Deathly Hallows

The structure of the game completely changes here. You are no longer safe in the halls of Hogwarts; you are on the run in the wilderness.

• Key Levels: The 7 Harrys, Sword and Locket, and Lovegood’s Lunacy.

• Essential Mechanics – Deluminator & Spectrespecs: Ron’s Deluminator allows you to absorb light from one source and transfer it to another, often melting ice blocks or growing plants. Luna Lovegood’s Spectrespecs are equally critical—wearing them allows you to see and interact with invisible LEGO bricks to build necessary tools.

Year 7 (Part 2) – The Final Battle

The climax of the game is action-heavy, requiring quick swapping and mastery of every spell learned so far.

• Key Levels: Gringotts Break-in, The Battle of Hogwarts, and Flaw in the Plan.

• Expert Tip: During the final showdown with Voldemort, pay close attention to the beam struggles. Mash the prompted button aggressively, but be prepared to quickly switch characters to manage Nagini and the incoming Death Eaters.

IV. The Hunt for Collectibles: Breaking Down the 100% Requirements

Achieving 100% means systematically sweeping the levels and the hub world for thousands of hidden items. Here is your roadmap.

Red Power Bricks (The Game Changers)

Red Bricks are hidden throughout the Hogwarts hub and can be purchased upstairs in the Leaky Cauldron. They offer powerful “cheats” that do not disable achievements.

• Score Multipliers (x2, x4, x6, x8, x10): These are your top priority. By finding them and turning them on simultaneously, your stud collection multiplies exponentially (up to x3840).

• Utility Bricks: Seek out the “Collect Ghost Studs,” “Character Token Detector,” and “Fall Rescue” bricks. The detector bricks are practically mandatory to save you from aimlessly wandering the castle for the final few collectibles.

Gold Bricks (The 200 Club)

There are exactly 200 Gold Bricks in the game, and finding them is the core metric of your completion percentage. Here is how the math breaks down:

• 96 Bricks: From completing the 24 story levels (1 for beating the level, 1 for True Wizard, 1 for the House Crest, 1 for the Student in Peril).

• 60 Bricks: Awarded for saving the 60 Students in Peril hidden in the hub world.

• 14 Bricks: Gained by completing story lessons in Hogwarts.

• 30 Bricks: Hidden throughout the hub world (Hogwarts, Diagon Alley, London, and the Tent).

Students in Peril (60 Total)

These poor Hogwarts students are trapped in spider webs, dangling from ceilings, or bullied by Slytherins.

• Pro-Tip: Never go hunting for Students in Peril without a character equipped with Dark Magic and Reducto. Many students are trapped behind silver statues or dark magical objects. Listen for their distinct cries for help when exploring the castle.

Character Tokens (200 Total)

Unlocking all 200 characters is a massive undertaking. While many unlock naturally through the story, others require solving obscure puzzles in the hub.

• Must-Have Hub Characters: Beyond a Dark Wizard and a Strength character, ensure you have a Goblin (like Griphook to open Gringotts safes), a character with a Pet (like Hermione’s cat Crookshanks to dig), and a Ravenclaw/Hufflepuff/Slytherin character to bypass the specific house portraits guarding common rooms.

V. Master the Hub: Navigating Hogwarts, London, and the Tent

Unlike the simpler hub of Years 1-4, the hub world in Years 5-7 is vast, fragmented, and occasionally confusing.

The Leaky Cauldron & Diagon Alley

The Leaky Cauldron is your base of operations. The notice board lets you replay levels, the upstairs room is for Red Bricks, and stepping out the back takes you to Diagon Alley. In Diagon Alley, visit Madam Malkin’s to purchase unlocked characters, and head into Knockturn Alley to find Borgin and Burkes (where you purchase Dark Wizards).

The “Hub” Logic and the Marauder’s Map

Hogwarts is separated into dozens of interconnected instances (the Grand Staircase, the grounds, the library, etc.). Use the Ghost Guide (Nearly Headless Nick). If you select a specific level or area from the pause menu, Nick will drop a trail of translucent blue studs to lead you exactly where you need to go.

The Wilderness (The Tent)

During the Year 7 segments, your hub shifts from Hogwarts to the wilderness campsites. Do not panic if you think you have missed collectibles here; you can access the Tent via a specific apparition point in London once you finish the game, allowing you to thoroughly sweep the forests and snowy plains for leftover Character Tokens.

VI. Expert Tips for Advanced Play

To elevate your game from casual fan to E-E-A-T certified LEGO expert, keep these advanced strategies in mind.

The “Stud Farming” Secret

To buy the x10 multiplier, you need millions of studs. The fastest way to farm studs is early in the game. Once you have the x2 and x4 multipliers, head to a level with infinitely respawning enemies or high-density stud rings (like The 7 Harrys flying sequence). Repeat the level on Free Play, collecting studs with the multipliers active. Within an hour, you will have enough to buy the x6, x8, and eventually the x10.

The Weasley Boxes

You will frequently encounter bright orange and purple boxes. Only members of the Weasley family (Ron, Ginny, Fred, George, Arthur, Molly) can interact with them. These boxes usually contain fireworks, sticky trainers (for walking up special walls), or decoy detonators. Always keep a Weasley in your active Free Play party.

Navigating Glitches: The 199/200 Bug

A famous issue in the LEGO gaming community is the “199/200 Gold Bricks” glitch. Sometimes, the Gold Brick detector will point to a space in the Library or the Clock Tower, but nothing is there.

• The Fix: Often, this isn’t a glitch, but a multi-step puzzle you partially completed. In the Library, ensure you have put all three hats on the wizards in the painting. If a detector points to the middle of the room, you likely need to sweep the perimeter, destroying every single object to trigger the brick’s appearance.

VII. Checklist: Essential Abilities Needed for 100%

Before tackling your massive Free Play sweep, cross-reference your character roster with this essential abilities checklist:

VIII. Frequently Asked Questions (FAQ)

How do I get back to the Leaky Cauldron from the Story?

If you are wandering Hogwarts and want to return to base, simply pause the game and select “Return to Leaky Cauldron.” You will not lose your overall game progress, but you will lose progress on your current level if you are in the middle of a story mission.

What is the best way to find the last Gold Brick?

Purchase and activate the “Gold Brick Detector” Red Brick. Systematically walk through every room in Hogwarts, Diagon Alley, and the Tent campsites. If the arrow points downwards into the floor, it usually means the brick is triggered by completing an environmental puzzle (like lighting all the torches in a room).

Which character is the most useful in Free Play?

A customized character or a Dark Wizard. However, Hermione Granger is arguably the most versatile base character, as she possesses a pet (Crookshanks), knows the Patronus charm, can read rune cabinets, and has a bottomless beaded bag (represented by the pink plates).

Are there any working cheat codes for LEGO Harry Potter 5-7?

Yes, there are codes you can enter at the board in Wiseacre’s Wizarding Equipment in Diagon Alley to unlock characters and Red Bricks early. However, entering cheat codes for Red Bricks can sometimes glitch your completion percentage. It is highly recommended to unlock the Red Bricks naturally through gameplay to guarantee 100% safety.

Achieving 100% completion in LEGO Harry Potter: Years 5-7 is a monumental task that requires patience, observation, and a methodical approach. It isn’t just about unlocking a digital trophy; it is about experiencing the sheer density of love and detail that Traveller’s Tales poured into this wizarding world adaptation. By utilizing this guide, securing your essential characters early, and methodically tackling the hub worlds, you will master the magic in no time.

Take your time, enjoy the whimsical LEGO humor, and keep your Gold Brick Detector turned on. You are now fully equipped to conquer the Dark Lord and claim your title as a True Wizard.
