After returning to SK recently, the casino gambling has kind of amazed me.
I personally like to gamble on things, and I want to make the golden slime casino even better!
I've come up with an ideal way this can be done.
Making an underground casino!
With various casino games with their own names similar to the gambling games we play.
So without further ado, Here are some of my ideal ways to make Spiral Knights better.

1. Lore idea.
The Spiral Order has noticed they're Knights are running low on resources and money to buy more! In order to keep up the fight and get back home quicker, the Spiral Order used their OWN secret bank (If they have one) to establish a Underground Area for Haven. Although this Underground is also used as a shelter if Haven were under attack. As for all the Weary Knights and the Knights who can't keep up the fight without proper funding, this casino is sure to help them raise their stacks and have a good time at the fundamentals of getting richer!

2. Don't make this an event.
The casino is built under the ground and should be accessible to ANYONE.
Although the drops of coins should be a bi-weekly event with higher drop rates.

3. Use one of the buildings behind the town square's Auction House in Haven as an entrance.
You know those buildings up there, right?
Use it as the entrance. It'll be useful for something at least.

4. The Golden Slime Casino's Currency
Let's say the primary currency for gambling in SK is the Golden Slime Coins. They are a ticket to good fortune as well.
1 slime coin in the current slot machine is 200 crowns.
So basically, 1 GSC can be purchased and sold for 200 crowns EACH.

5. Games
Although the current function of gambling is the slot machines, I've came up with a few ways to make the casino "interesting"
Players will compete against each other when there are 2 players or more.
The player that wins, get's the prize pool that everyone has gambled with.
The loot that is not in the pool, stays with the player.

When the player plays the game, an interface pops up on screen and this is where the player plays.
And the max number of players that can play in a game is 4

-Royal Candy Dish (Poker)
The game is basically played as Poker but, the name and cards are different to make it suitable for Spiral Knights - friendly.
The deck of cards is candy-styled.

-Sticky Nick Nacks (Black Jack)
Sticky Nick Nacks uses a deck of slime pictures on the cards.

- Speedy Sparky (Race game)
A player must RAPIDLY press W and the first one to win gets a prize!

- Cheesy Kings (Chess)
The players bet the same amount, and the winner of the game gets the win.
This game is 2 players only.
Cheesy Kings uses yellow and white chess pieces indicating a type of Cheese. Cheddar Cheese and Swiss Cheese.

- Keeping the slot machines in game!

6. Tutorials
When playing a game from the casino, you may be prompted a box asking if you wish to learn to play.

7. Guild Hall Casino
Basically everything in the underground casino, in your own guild hall!
How exciting!

Anyways, thank you for reading this and I hope to see some responses below!

Edit : I'm thinking of drawing some concept art for the idea.
