Project: Development of a 3-Wheel Pre-Determined Win Game (C# / Python) with CCTalk Integration Overview We are looking for an experienced developer to build a simple 3-wheel LED game for a touchscreen gaming machine running Windows 11. The game uses a pre-determined sequence of 20,000 spins to control RTP and outcomes. It must integrate with Microcoin SP and Astrosystems ST2 note/coin acceptors via CCTalk protocol using a VAL362 interface. The game flow is simple and fully automated except for the Double feature. Graphics will be provided. Developer will provide sound, animations, coding, and CCTalk integration. System Requirements - OS: Windows 11 - Screen: Touchscreen vertical (9:16) layout Hardware: - Microcoin SP coin acceptor - Astrosystems ST2 note acceptor - VAL362 CCTalk interface - Connection: Standalone (no internet) - Performance: Low-intensity, runs on modest PC hardware Game Flow State machine: Idle → Insert Money → Auto Play (uses credits) → Nudge (if applicable) → Double (player option) → Return to Idle - Idle: LED animations + sounds. - Insert Money: Credits are added. - Auto Play: Spins automatically until credits are exhausted or nudge feature triggers. - Nudge: Pressable key. - Double: At the end of a winning spin (above 1 credit), the player can choose to double. - Screen shows two chests — the player taps one. - If correct, winnings are doubled; if wrong, winnings are lost. - Mini-games: All automatic. Return to Idle: If credits = 0. Predetermined Spins System - 20,000 spin sequence stored in a text file. - File structure suggestion (flexible for freelancer): R1.1 R2.17 R3.12 R1.2 R2.14 R3.4 ... (R1, R2, R3 = 3 wheels; .1–.n = LED positions) A Python script must be written to: - Generate the list based on provided distribution table (medium volatility). - Verify RTP = 78% over 20k spins. - Verify the machine never exceeds 85% RTP at any point in 20k spins. - After the 20,000th spin, the list loops back to the beginning. Double feature win rate: ~30% of prize spins. → We welcome freelancer’s suggestion on how to best integrate this into a pre-determined spin structure (e.g. separate file, flags in spin list, or RNG layer on top of fixed outcomes). Game Features - Nudge - automatic when triggered. - Double - manual by player (chest selection minigame). - Pool - Each losing spin contributes 0.02 credits. When pool = 100, award to active player, then reset. - Mini-Games - Two types remain: - Random Prize: all LEDs light up, turn off one by one until one prize remains. - LED Elimination: winning LEDs flash until one remains. - Play with Credits - Players can use won credits to play manually. Graphics, Sound & Presentation - Graphics: All provided. - Sound: Developer must supply royalty-free SFX (spin, win, background, etc.). - Animations: Idle animations when machine is not being played + Spin animations - Simple effects to make the game visually pleasing Statistics Screen - Accessible via macro key sequence + password. - On-screen only (no exporting). - Must display: - Total credits in / out - Total spins - Wins & losses - Double wins/losses - Pool contributions & payouts - Mini-game triggers Tech Stack - Frontend / Game: C# (Visual Studio) - Backend / Scripts: Python for spin generation & RTP check - Protocol: CCTalk for hardware comms - Documentation: Required - Source Code: Full source code & project files must be delivered Project Milestones Milestone 1 - Core Game Prototype (20%) - Basic 3-wheel LED system implemented - Reads and loops predetermined spin list - Idle/Insert/AutoPlay basic flow - Initial test with keyboard inputs Milestone 2 - Game Features & CCTalk (25%) - Nudge, Pool, Double, and Mini-games implemented - CCTalk communication with note/coin acceptors working - Basic sound and LED animation Milestone 3 - Spin Generation & RTP System (20%) - Python script to generate & verify spin list (78% RTP) - Integrated with game loop - Handles looping after 20k spins Milestone 4 - Polish & Statistics (20%) - Statistics screen with password protection - Full game flow functional on touchscreen - Graphics and sound integrated properly Milestone 5 - Final Delivery & Testing (15%) - Final bug fixing and delivery - Full documentation and source code - Testing on actual hardware Required Experience - Proven experience in C# game development (preferably in Visual Studio) - Familiarity with CCTalk protocol and handling peripheral devices - Experience writing Python scripts for data generation / validation - Understanding of arcade or SWP (Skill With Prize) machines is a major plus Additional Info - Graphics assets and prize distribution table will be shared with the chosen freelancer. - All code must be delivered in fully working order. - Communication in English is required.
