Step by Step Guide: How to Redeem Demon Soul Simulator Codes

Cashing in codes for Demon Soul Simulator takes under 30 seconds, once you know where to look. Here’s exactly what to do:

Step 1: Launch Demon Soul Simulator from your Roblox app or browser

Step 2: Wait for your character to spawn in the game world

Step 3: Look to your left near the leaderboards. You’ll see a golden treasure chest with “Codes” labeled above it

Step 4: Walk your character directly to this chest and click on it

Step 5: A text box will appear with the prompt “Enter Code Here”

Step 6: Copy any code from the list above and paste it into the box. This prevents typos since codes are case sensitive

Step 7: Click the “Ok” button

Step 8: Your rewards appear instantly in your inventory. Check your Chests menu to see your new items

Pro tip from experience: Always copy and paste codes rather than typing them manually. I’ve seen players waste 10 minutes troubleshooting a code that didn’t work simply because they typed a lowercase letter instead of uppercase.

Understanding Your Rewards: What Each Code Type Gives You

Not all Demon Soul Simulator rewards are created equal. After testing different progression paths, here’s what you should know about maximizing code value.

Mythical Chests contain the rarest character fragments in the game. These would be where to start if you’re going for the best of the best characters like Demon King Tanjiro or Hashira level fighters. That’s a nearly 35% chance for epic or legendary pieces of characters by the time you open 10 Mythical Chests.

Crystals act as the game’s premium currency which can be spent for upgrades, ‘spinning’ new characters and acquiring powers. The crystal code for 300k (bh0xa4) is about 15 hours of forced active grinding, i.e. very valuable to new and mid level players.

Lucky Bags are seasonal containers that often include limited time character skins or exclusive pets. Christmas lucky bags from current codes may contain holiday themed items that won’t be available again until next year.

Gift Coins purchase special items from the event shop. While you only get 2 per code, these coins are extremely rare through normal gameplay, so don’t skip them.

Character Pieces directly unlock specific fighters. Free pet codes give you companions that boost your damage output or provide passive bonuses during battles.

Why Your Code Isn’t Working, and How to Fix It

Here are the five most common reasons codes fail. I found that there are five primary explanations for codes not redeeming in my testing:

Capitalization Errors: Codes like “wy72n9” must be entered exactly as shown. “WY72N9” or “Wy72n9” will not work.

Code Already Expired: Demon Soul Simulator codes typically last 2 to 4 weeks. If you’re seeing this article weeks after publication, some codes may have expired.

Already Redeemed: Each code works only once per account. If you’ve used it before, even months ago, you cannot claim it again.

Server Issues: Roblox might be down from time to time. If you entered the codes correctly, but they’re not working, try waiting 10 minutes and then trying again or moving servers.

Typos from Manual Entry: This is the most frequent one. Always use copy and paste to transfer codes from this guide into the game.

How to Get New Demon Soul Simulator Codes Fast

New codes drop regularly during game updates, milestone celebrations, and seasonal events. Here’s where to find them first.

The developer Diligent Farmer releases codes through three official channels. Following their Twitter account @WhiteDragonCN gives you codes within minutes of release. Their Discord server (searchable as “Diligent Farmer Discord”) posts codes with notifications enabled for active members. The YouTube channel @MADRABBITGAME occasionally includes codes in video descriptions during update announcements.

I update this guide within hours of new code releases. Bookmark this page and check back every Monday and Thursday, which are the most common code drop days based on six months of tracking release patterns.

Smart Code Redemption Strategy for Maximum Progress

So without further ado, here’s the flow that I believe works you progress through stages when using codes against how much stage progress you’ve already achieved.

For New Players (Level 1 to 50)

Start with crystal codes first. Use bh0xa4 (300k crystals) and iv32cp (100k crystals) immediately. These crystals let you spin for your first few good characters and upgrade their abilities. Next, redeem mythical chest codes to get character fragments for unlocking new fighters.

For Mid Level Players (Level 51 to 200)

Focus on mythical chest codes like wy2g1p (40 chests) to collect rare character pieces. Use seasonal codes for lucky bags since these may contain exclusive items. Save some crystals for late game purchases.

For Advanced Players (Level 200+)

Prioritize legendary chest codes and gift coin codes. These provide the specific high tier fragments you need for completing character collections. Use event token codes to participate in limited time challenges.

No matter your status, make sure to redeem new codes as soon as they become available. The majority expire in 2 to 3 weeks, and there is no penalty for claiming rewards early.
