# Changing Odds

There are a few options that let you change the winning odds for the table games. These options can be found in **const.lua**

### Blackjack (BlackjackTableData in const.lua)

```
DealerBlackjackPossibility = 25
```

This value represents the percentage chance that the dealer will get a blackjack (Ace + 10-value card) at the start of each round. By default, this is set to **25%**. Increasing this number makes blackjack more frequent for the dealer, making the game harder for players.

```
Dealer21Possibility = 25
```

This value determines the dealer’s chance of reaching a total of **21** through multiple draws in a round. Set at **25%** by default, increasing this value makes the dealer more likely to reach a perfect score.

### Poker (PokerTableData in const.lua)

```
UnluckyRound = 3 
```

By default, **every 3rd round** is designated as an "unlucky round" for the player, meaning there is a higher chance of receiving weak or unplayable cards. Increasing this number makes unlucky rounds less frequent, while lowering it makes the game more difficult.

### Roulette (RouletteTableData in const.lua)

```
UnluckyRound = 4
```

On **every 4th spin**, the wheel is more likely to land on a number that **players have not bet on** or on a number that minimizes the casino’s losses. Lowering this number increases the frequency of these unlucky rounds.

```
TriggerUnluckyRoundFrom = 10000
```

If the potential payout for a spin would cost the casino **more than 10,000 chips**, the game will automatically choose an unlucky number instead. Adjust this value to change when the casino begins rigging spins to minimize losses.

### Lucky Wheel (LuckyWheelItems in const.lua)

```
possibility = 100
```

Each item on the Lucky Wheel has a **possibility** value, which works like a weighted lottery. The higher the number, the greater the chance that item will be selected. These values are not percentage-based but instead represent **relative weight**—if an item has `200` and another has `100`, the first item is **twice as likely** to be chosen. Adjust these values to control the rarity of different prizes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.rcore.cz/paid-resources/rcore_casino/changing-odds.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
