Game Title (WIP Name): Spin For Luck
Genre: Casino / Slot Machine Simulation
Platform: PC & Mobile (prototype)
Engines: Unity (C#) & Unreal Engine (Blueprints/C++)
Target Audience: Casual players, 18+ (simulation only – not real money gambling)
Core Goal: Create a simple yet functional slot machine prototype to demonstrate core gameplay mechanics, user interaction, and modular design for future expansion.

2. Core Gameplay

• The player presses a Spin button to activate the slot machine.

• Three reels (initial prototype) spin and then stop sequentially.

• Matching symbols across the payline trigger a win state with a payout.

• Player has a limited set of virtual credits to bet with.

• Winning adds credits, losing subtracts credits.

4. Technical Design

Unity Implementation (C#)

• Reel System:

  • Reels implemented as arrays of symbols.

  • Randomization using Random.Range() to select results.

  • Coroutine-based spin/stop animation.

• UI: Unity UI system for credits, spin button, win display.

• Data: ScriptableObjects for symbol data (symbol, rarity, payout).

• Audio: AudioSource components for spin & win sounds.

• Future Expandability: Prefab-based reels for scalability (e.g., more reels, more symbols).

​

​

Unreal Engine Implementation (Blueprints & C++)

• Reel System:

  • Blueprint Actors for each reel.

  • Timeline node for spinning animation, stopping sequentially.

  • Random number generation via UKismetMathLibrary::RandomIntegerInRange.

• UI: UMG Widgets for credits, buttons, and payout notifications.

• Data: DataTables for symbols (symbol name, probability, payout).

• Audio: Sound Cues triggered via Blueprint events.

• Future Expandability: Modular reel blueprint that can be duplicated and adjusted.

5. Gameplay Loop

1. Player starts with 100 credits.

2. Player selects bet size (default = 1 credit).

3. Player presses Spin → reels spin.

4. Reels stop → system checks for win condition.

5. Payout applied if win → credits updated.

6. Repeat until credits reach 0 (game over) or player quits.

​

​

6. User Experience (UX)

• Clean & Minimalist UI for prototype.

• Clear feedback on wins/losses.

• Smooth reel animations for immersion.

• Quick play sessions (spins last 2–3 seconds).
