The success of a gacha relies on a few important points that will be explained in this article. The following tips will focus on gacha keys and composition to ensure a successful gacha experience, for you and your customers!


A well composed key will tell the customer everything they need to know about what they are buying, in one image. So it is essential to explain if your product is animesh, a pet or an avatar, if a skin is Bakes on Mesh compatible or Omega, if clothing fits certain bodies and so on.

We’ll use ::Static:: Gacha keys for our examples.

• The popular gacha key image ratio is 1:1 (512×512 or 1024×1024). It’s the most widely accepted at events and it just looks nice. It’s required 1:1 for uploading to the .Gacha Guild. website, however you can honestly make any ratio you want elsewhere.

• The first thing customers look for is the rarity of what each pull will be. They want to know the odds of what they are playing for. Make it easy for them and number the gachas. You don’t want to miss plays because the customer was confused and gave up trying to figure it out. It is important to name the actual gacha in a similar way so they can match it up in their inventory.

• Enlarge one example so the customer can see the detail, and then smaller ones around it to display the variety. This is an effective way to use space and show off the quality of the gacha item.

• If the item has a “use” like above, such as being held, mention that! Or even better, show that, if you have space on the key.

• If the gacha has just too many color variations or parts to be shrunk down, you could do a trick like this to show how many colors each element in your gacha has. The result is a cleaner, more polished looking image.


The purpose of a gacha is to inspire people to keep playing. The best way to do that is to have a variety that keep people interested and coming back.

• Having too few items in your gacha is not ideal for the reason above. If you have 6-10 items in your gacha, people will likely play 6 times and have every item they want, rare or otherwise because there’s not enough commons to make the uncommons infrequent, or the rares truly rare… then they’ll stop playing.

• Suggested numbers. With the minimum of 10 commons, have 3-5 uncommon, and 1-2 rare. Maybe one ultra rare if you’re feeling frisky. That would give you 14-18 total items, a fair prize pool to pull from.

• For gachas with a large prize pool of 40-50, the ratio could stay the same but you really have to work to make the rares spectacular or coveted in some way to make it worth playing for. Here’s a larger gacha as an example:

• Item variation. Some gachas do recolors between rarity, some have a different mesh for every single item, but the main thing is, you’ve got to make people want those items. Especially rares. Focus on making your rares irresistible to play for, your uncommons special and your commons ordinary. Going the extra mile with your rares is worth it for the additional plays it will yield.

• Fairness. Think of yourself as a customer when you price your product and decide the rarity from their perspective. What you would pay for, and if it is fair when you are the customer? If you wouldn’t try to play, why would anyone else? Nobody wants to discourage or disgust a customer with impossibly low rare chances. They’re in it to have fun and will keep coming back to win more IF they feel like they can win. The gacha game inspires players to feel good. Tap into that.


We put limits on the gachas in the event to keep things fair, and it’s all from experience of having the event run for 4 years. Here’s a recap of our gacha guidelines for your reference:

• All gachas must have these permissions: No Copy and Transfer
• Key aspect ratio of 1:1 (512×512 or 1024×1024)
• No single pull should be priced over 100$L
• No single machine should have more than (50) items in it
• (2) secret rares allowed per machine and must be indicated on the gacha key in some way.
• Keys and item prizes must be numbered properly so the customer knows what they’re getting.
• If you want to have a gacha with more than (50) items, you can split it up into two machines like the example below:
