Slot Machine

A terminal-based slot machine game built in Go. Place your bet, spin the reels, and win based on symbol multipliers — or lose your balance trying.

Demo

Welcome to Show's Casino...
Enter your name: Show Manny
Welcome Show Manny, let's play!
Enter your bet, or 0 to quit (balance = $200): 50

C | A | B
C | C | C   Won $250 (5x) on Line #2
D | A | B

Enter your bet, or 0 to quit (balance = $400): 0
You left with, $400.

How It Works

1. You start with a balance of $200.
2. Each round you enter a bet amount.
3. Three reels spin and display a 3x3 grid of symbols.
4. If all three symbols on a row match, you win your bet multiplied by that symbol's multiplier.
5. The game ends when your balance hits $0 or you choose to quit.

Symbols and Multipliers

Symbol	Multiplier	Rarity (weight)
A	28x	4
B	10x	7
C	5x	12
D	2x	20

Rarer symbols pay out more. Common symbols appear more frequently but pay less.

Project Structure

slot-machine/
├── main.go      # Entry point, core game loop, and checkWin logic
├── spin.go      # GenerateSymbolArray, GetRandomNumber, GetSpin, PrintSpin
└── utils.go     # GetName, GetBet — handles all user input

All files share package main and compile together as one program.

Concepts Demonstrated

• Maps — used as lookup tables for symbol weights and multipliers.
• 2D slices — [][]string represents the slot machine grid.
• Unsigned integers (uint) — balance and bets are always non-negative.
• Game loop — for balance > 0 keeps the game running until the player runs out of funds or quits.
• Multi-file structure — logic is split by responsibility across separate files.
• Functions with return values — checkWin evaluates each row and returns a slice of winnings.

Running the Program

From inside the project folder:

go run .

Use go run . (not go run main.go) since the project spans multiple files.
