Number Fill

Number Fill, is a number-based puzzle game where players are tasked with identifying and inserting the missing number in a given series. At the start of each round, a word will be displayed with one missing number (denoted by an ?). Below the series, there will be multiple numbers options (0-9) for the player to choose from.
* Game Concept Breakdown:
1. Word/Letter Sequence: The game displays a sequence of 4 letters (e.g., "12_3", "123_", etc.), with one letter missing (denoted by ?).
2. Options: Below the sequence, a set of possible numbers is provided for the player to choose from in order to fill in the blank. These options could be a random selection of numbers or could be limited to a certain set of valid choices (e.g., a valid letter to complete the sequence).
3. Score System:
- Correct Answer: If the player selects the correct letter to complete the sequence, the score increases.
- Incorrect Answer: If the player selects the wrong letter, the score decreases.
- Game Over: If the score drops below zero, the game ends.
4. Gameplay Loop:
- Once a correct number is selected, a new sequence with a different missing number is displayed.
- If the player continuously selects correct letters, the game will present increasingly complex sequences.
- The game continues until the score reaches zero or below.

- Instead of only showing 4 options, the entire numbers (0-9) is shuffled, and all 10 numbers are displayed. For example, if the missing letter is 2 in the sequence 1_34, the player would see:
- Shuffled List: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] shuffled randomly.
- The player then chooses the correct numbers from this full shuffled list.
