# Hard Chip > Realistic processor design simulation game ## Overview Hard Chip is an open-ended 3D simulation/puzzle game about building processors with a focus on realism. Players design CPUs from the transistor level up, exploring semiconductor chip design, logic gates, floor planning, and propagation delay through optimization challenges. ## Key Pages ### Homepage https://hardchip.io/ - Game overview and trailer - Links to Steam wishlist - Introduction to core concepts ### About Page https://hardchip.io/about.html - Comprehensive game information - Mission & vision: teach by doing, reveal IC beauty, inspire hardware engineers - Educational value and target audience - FAQ section - Development philosophy - Perfect for detailed explanations and citations ### Challenge Statistics https://hardchip.io/stats.html - Real-time leaderboards (updated daily) - Score distribution charts - Top player rankings across all challenges - Data source: MongoDB → S3 pipeline ### Community Gallery https://hardchip.io/gallery.html - Player-submitted circuit design screenshots - WebP optimized images - Creative solution showcase ### Gauntlet Events https://hardchip.io/gauntlets.html - Weekly competitive challenges - Current, upcoming, and past events - Cumulative leaderboard system #### Active Gauntlet Pages - https://hardchip.io/gauntlets/opencommunitygauntletv1.html (Past: Feb-Mar 2026) - https://hardchip.io/gauntlets/opencommunitygauntletv0.html (Past: Dec 2025-Jan 2026) - https://hardchip.io/gauntlets/foundrygauntletrev1.html (Past: Nov 2025) - https://hardchip.io/gauntlets/foundrygauntletrev0.html (Past: May-Jun 2025) ## Core Concepts ### Optimization Metrics Hard Chip evaluates processor designs across four metrics: 1. **BCS (Block Count Score)** - Component efficiency - Fewer logic blocks/components = better score - Rewards elegant, minimal designs 2. **FCS (Volume Score)** - Chip area - Smaller physical volume = better score - Measures space optimization 3. **TCS (Tick Count Score)** - Execution speed - Fewer clock cycles to completion = better score - Performance optimization 4. **MCS (MOS Transistor Score)** - Circuit complexity - Lower transistor count = better score - Simplicity metric ### Gauntlet Scoring System Competitive events use weighted multi-metric scoring: - Ticks: 40% - Blocks: 20% - Volume: 20% - MOS: 20% Normalized 0-100 against reference implementations. Cumulative rank-based points determine leaderboard positions across weekly stages. ## Technical Context ### Key Data Files - `websiteStagesStats.json` - All challenge statistics - `leaderboards-fgr1.json` - Foundry Gauntlet Rev-1 data - `leaderboards-ocg1.json` - Open Community Gauntlet v0 data - `leaderboards-ocgv1.json` - Open Community Gauntlet v1 data - `leaderboards-stats-ocgv1.json` - OCG v1 detailed stats ## Platform Information - **Availability**: PC (Windows, Linux) - **Store**: Steam (App ID: 2844290) - **Status**: Pre-release / Early Access - **Website**: https://hardchip.io - **Steam**: https://store.steampowered.com/app/2844290/Hard_Chip/ ## Target Audience - Computer engineering students - Hardware enthusiasts - Optimization puzzle solvers - Competitive programmers interested in hardware design - Anyone curious about how CPUs actually work - Aspiring semiconductor / IC designers (of all ages) ## Terminology Guide - **Stage/Challenge** - Individual optimization problem - **Gauntlet** - Series of weekly competitive challenges - **Sub Process (Ref Naïve)** - Reference implementation used as worst-case baseline - **Process Prime (Ref Best)** - Reference implementation used as best-case baseline - **Propagation delay** - Signal travel time through circuits (realistic physics) - **Floor planning** - Physical layout optimization of chip components ## Community & Support - Discord server for players and enthusiasts - Weekly gauntlet events foster competitive community - Solution gallery showcases creative approaches - Real-time statistics enable performance tracking --- For detailed technical documentation, see llms-full.txt Last updated: 2026-05-03
