Roblox's Infinity Gauntlet | Thanos Simulator, developed as a solo project by Blg42598, features several symbol, number, and rune-based puzzles required to unlock endgame weapons and their forged upgrades. Solving these mechanisms grants access to World5, decodes the chest patterns for the upgraded Mjolnir, and completes the cipher room needed to summon Surtur for the Twilight Sword.
Because failing or mismanaging enemies in these puzzle chambers can reset sequences or eliminate your character, understanding the exact activation steps and trap mechanics is essential.
World5 Portal Symbol Puzzle (Casket of Ancient Winters)
According to the Thanos Simulator Official Wiki, reaching World5 requires players to decipher an environmental symbol sequence rather than brute-forcing combat.
Activating the Portal Statues
- Travel to the portal entrance area outside World5.
- Locate the three statues marked with symbols surrounding the platform.
- Equip the Infinity Gauntlet (or Upgraded Infinity Gauntlet).
- Fire the Disintegrate ability (bound to the E key) at the three statues in the specific mathematical sequence indicated by the environment: the center platform operates in base 3, while the outer rocks operate in base 4.
- Once struck in the correct sequence, the central portal emits a physical shockwave that knocks back your character, opening the gateway.
Entering the portal immediately closes it behind you. If you are playing with others, each player must reopen the portal individually if they do not step through simultaneously. Clearing the subsequent two phases against Lazarus and hitting the glowing neon rock in the floating ring area awards the Casket of Ancient Winters and the World5 badge.
Upgraded Mjolnir Robe Symbol Sequence
Upgrading Mjolnir requires solving a visual glyph cipher located inside the temple forge area. The badge description notes that "The Key to this power has been guarded for 2000 years." Community gameplay recordings document specific rules that dictate how this puzzle functions.
| Puzzle Step | Required Action | Critical Condition / Caution |
|---|---|---|
| Room Preparation | Rotate all temple lights until they align to blue | Place standard Mjolnir onto the center pedestal |
| Mob Management | Herd or trap spawning NPCs without killing them | Eliminating NPCs resets the cipher solution |
| Glyph Inspection | Read the symbols displayed across an NPC's chest/robe | Read strictly from left to right |
| Code Input | Shoot the corresponding wall symbols matching the chest pattern | Maintain shields or freezes while entering |
| Completion | Enter the final matching glyph | Awards the "Upgrade Mjolnir" badge |
Preventing Code Resets
When you deposit Mjolnir, robed NPCs immediately populate the room. A critical puzzle rule documented in player guides is that killing these NPCs resets the code.
To bypass this without taking lethal damage, players use crowd-control mechanics:
- Use the Space Stone's ability to manipulate geometry, trapping NPCs behind walls or corners so they cannot hit your avatar.
- Alternatively, apply the gauntlet's freezing abilities to anchor a single NPC in place while isolating the others in distant corners.
- Keep one trapped NPC visible to inspect the symbols printed across their chest piece.
Zoom in or take a screenshot of the robe glyphs. Aim at the puzzle targets on the wall and activate your shot (using your gauntlet ability) matching the chest pattern from left to right. Successfully entering the full sequence awards the Upgrade Mjolnir badge and unlocks the upgraded hammer's rock-projectile ability (bound to X).
Surtur's Lair Number and Circle-Dot Rune Puzzle
Unlocking Surtur's Twilight Sword involves solving a chamber puzzle where circular rune formations correspond directly to wall numbers. Accessing this chamber requires the Heart of Ymir (obtained from World5) and the Hadron Enforcer.
Accessing the Rune Chamber
- Teleport to the underworld gate area and execute the Snap of Ymir.
- Charge the Infinity Gauntlet and use Disintegrate (E key) on the entrance door.
- Stand on the platform until the lava recycles, then execute the Snap of Ymir again to open the inner chamber.
- Place the Heart of Ymir on the pedestal, eliminate the shielded guards by breaking their shields with the Hadron Enforcer, and clear the room.
- Advance down the corridor and use Disintegrate to open the puzzle door.
Translating the Rune Symbols to Numbers
The puzzle chamber contains several numbered targets on the wall. The numbers you must shoot are not displayed in plain text; instead, they are scattered outside the immediate chamber as geometric circle-and-dot symbols:
- Step onto the scanner pad inside the chamber to initiate the sequence.
- Teleport back toward the outer threshold and zoom your camera out into the surrounding void.
- Scan the exterior walls and rock formations for glowing circle-and-dot arrangements. Each formation represents a specific number (such as 3, 9, 7, 6, 11, or 5).
- Identify which symbol currently appears in the sequence, return to the chamber, and charge your gauntlet.
- Shoot the matching numeric target on the wall using Disintegrate (E key).
- Repeat this process for each subsequent rune location until all required numbers are activated. The final remaining number can be shot directly once all other targets are lit.
Completing the sequence spawns the summoning crystal. Inserting this crystal into the boss pedestal summons Surtur. Recorded player clears show that freezing Surtur with the Snap of Ymir while spamming charged projectile strikes—or using the Time Stick directly on his head—defeats the boss and yields the Sword of Surtur.
Upgraded Sword of Surtur Temple Puzzle
Once the base sword is acquired, players can upgrade it inside the secondary temple zone:
- Rotate all surrounding pillar lights until they turn red.
- Spawning enemies will enter the arena; manage your health pool using the Scepter gamepass or healing abilities while targeting the numeric markers on the walls.
- Shoot each required number while clearing hostile minions.
- Place the standard Sword of Surtur onto the central altar once all nodes are satisfied.
- Defeat the remaining waves to unlock the "Upgrade Sword of Surtur" badge, which unlocks the weapon's Q ability to summon minion waves.
Frequently Asked Questions
Why does my Mjolnir puzzle code keep changing or failing?
The code resets every time an NPC in the puzzle room dies. To keep the code stable, do not kill the spawned robed figures. Trap them inside walls using the Space Stone or anchor them with freeze abilities while reading the chest markings from left to right.
What happens if I fail the timer after opening the World5 portal?
According to the official wiki, players have 240 seconds total: 60 seconds to enter the island portal after defeating Lazarus and 180 seconds to claim the Casket of Ancient Winters. If the timer reaches zero, the player is frozen and killed by the blizzard effect unless protected by the Infinity Gauntlet's shield.
How do I break the shields on the guards in Surtur's temple?
Player playthroughs demonstrate that shooting the guards with the Hadron Enforcer shatters their protective shields, allowing standard gauntlet abilities and weapons to deal damage.
