THE GAME BEHIND THE CARDS
How Extreme Demon Gacha works
Extreme Demon Gacha is a fan-made browser card game built around Geometry Dash Extreme Demon levels. Instead of beating a level, you collect its card: the level name, creator and rank become part of a collection you can build and trade.
The original game is at demongacha.com. This companion gives you a practice pack simulator, a searchable card catalog and calculations that explain the numbers. Practice pulls stay here; they never become cards in your game account.
FAMILIAR LEVELS, DIFFERENT RARITIES
Browse all 1,620 cards ↗Find the level you know.
A famous level is not automatically a rare card. The current tiers follow AREDL rank, and individual cards within each tier still have different drop rates. Start with a name you recognize.
BEFORE YOU CHASE AN APEX
What your odds actually say.
100 packs can still miss.
At the snapshot’s GRIEF probability, 100 packs give about a 2.13% chance of at least one copy. Missing after that many packs is the common outcome, not evidence that your account is unlucky.
An even chance at GRIEF.
GRIEF reaches a 50% chance at about 3,221 packs. Half of independent sequences would still miss it. An average wait and a probability threshold answer different questions.
Any Holo is a different chase.
With a 10% Holo roll in each of 5 slots, a pack has about a 40.95% chance of containing a Holo. A Holo of one particular rare level can still take a very long time.
The calculator uses 1 − (1 − p)^(5 × packs) for independent slots. It follows the published probabilities; it does not audit the original server’s random draws. Run a calculation for your own target ↗
COLLECTION POINTS
Your first copy matters most.
The score model used by these tools discounts repeat copies. A first normal copy contributes the card’s full value; the second adds half, the third adds a third, and later copies continue the same pattern.
Holo copies occupy the first positions at three times the value. That means the score impact of a trade depends on what you already own, not just the rarity names printed on the cards.
Consider a card with a 1,000-point normal value:
| Your copies | Score for this level |
|---|---|
| 1 normal | 1,000 pts |
| 2 normal | 1,500 pts |
| 3 normal | 1,833.33 pts |
| 1 Holo + 1 normal | 3,500 pts |
A SIMPLE COLLECTION ROUTINE
When to open packs and check trades
Watch the storage cap.
The documented free-pack system gives one pack every 10 minutes and stores up to 10. Accumulation stops when storage is full. The 144-pack daily figure is a theoretical ceiling, not a requirement to keep checking all day.
Choose a target.
Look up a card you actually want, then calculate the chance at a realistic number of packs per day. Comparing a goal with your own pace is more useful than reading a single “1 in” number.
Check before you swap.
Know which cards are your only copies and which are duplicates. Use the score worksheet for the exact cards on each side, then decide how much personal preference matters.
Treat codes as dated reports.
Bonus codes can expire or run out. Our record labels the reported code as untested and links to the original game for redemption. Only the original game can confirm a successful redemption.
GOT QUESTIONS?
Is this the original Extreme Demon Gacha game?
No. Extreme Demon Gacha Tools is an independent companion. These tools do not access your game account. To collect real cards, use demongacha.com.
Can I use this without a Discord account?
Yes. The tools and practice simulator need no login. The original game has its own Discord sign-in requirements, including a minimum account age.
Are the simulated drop rates the same as the game?
The simulator samples from a local snapshot of the probabilities published by the game's public rates API. Each slot gets a separate draw and a 10% Holo roll. We cannot audit the original game's live random draws.
Does a Holo Legendary beat a normal Mythic in a trade?
It depends on the exact cards, your existing copies, and whether you care about points or rarity. Compare the score impact here; player demand is not captured by a point formula.
Where does my practice collection go?
It is saved in this browser's local storage. It does not sync across devices or transfer into the original game. Export a JSON backup before clearing browser data.
How is the data updated?
We check the original game’s public rates daily and publish changes after validation. The date below the tools shows when your copy was last refreshed.
Do I need a Geometry Dash account to use the tools?
No. The tools need no account at all. The original card game has a separate Discord login; it does not require your Geometry Dash progress to run these companion calculations.
Why can’t a new Discord account enter the game?
The currently documented game rules require a Discord account at least 30 days old. This is controlled by the original game. Our simulator and card catalog remain available without Discord.
How is Bloodbath’s rarity assigned?
Rarity is based on rank in the All Rated Extreme Demons List rather than fame. Check the Card Atlas for its current rank and tier. Its individual probability is still only one card’s share of that tier.
Can a card change rarity later?
The snapshot uses fixed rank cutoffs. If the underlying list changes, a level near a boundary can move into another tier. Check the snapshot date before assuming old values still match the live game.
Do these tools include Limited cards?
The simulator includes the 1,620 cards in the public rates distribution. Cards that do not drop from that pool are excluded so they are not accidentally awarded in a practice pack.
Does opening more packs improve the next pack’s chance?
Under the independent-draw model used here, the probability of each next slot stays the same. More packs improve your cumulative chance, but previous misses do not improve a future slot.
Are codes guaranteed to work?
No. The code record is dated and explicitly distinguishes a player report from a verified redemption. We do not label an untested report as an active code.
Can the trade worksheet tell me a card’s cash price?
No. It calculates collection-score changes under the documented copy model. It does not provide a marketplace price, an account valuation, or a guaranteed fair-trade verdict.
