Recall Gears

Welcome to the boiler room, Engineer. A high-stakes, steampunk-themed cognitive training game that elevates the classic memory sequence mechanic into a thrilling industrial simulation. Built with rich, interactive physics and a dynamic audio engine, your task is to keep a volatile machine stable by matching rhythmic sequences of glowing, musical gears. But this isn’t just a simple memory game—it’s a true test of focus, spatial awareness, and working memory under pressure! TACTILE, HIGH-STAKES GAMEPLAY Physical Controls: Don't just tap a "Start" button. Grab and spin the heavy brass Ignition Valve to fire up the engine, and slide the Aperture Control to physically scale the gears while you play. The Boiler Pressure System: Mistakes don't just cost you points; they build up dangerous steam pressure. Vent the pressure by successfully completing sequences, or face a catastrophic System Failure! Overdrive Mode: Hit a flawless streak of 5 sequences to push the engine into Overdrive! The machine spins faster, the pitch intensifies, the core glows red-hot, and you earn double points. 4 ADVANCED COGNITIVE MODES Train your brain with modes designed by cognitive science principles to stretch your working and spatial memory: CLASSIC: The traditional sequence challenge. Observe the musical pattern and mirror it back. SHIFTING: The engine plays the sequence, then blasts steam and physically shuffles the gears around the screen! Memorize the pitch and color, not just the location. REVERSE (Working Memory Manipulation): Watch the pattern, hold it in your mind, and input the entire sequence backwards. N-BACK (Continuous Memory): A relentless, never-ending loop. The engine doesn't stop to wait for you—you must constantly tap the gear that lit up exactly N steps ago while absorbing the new incoming sequence. THE ENGINEERING SHOP Every cycle you survive banks currency. Spend your hard-earned cycles in the Shop to fully customize your machine: Gear Designs: Swap out the classic cogs for razor-sharp Sawblades or sleek Turbines. Color Palettes: Equip heavy alloys or hazard warning colors. Aesthetic Themes: Unlock 7 radically different visual styles, including the gritty Biohazard, the luxurious Clockwork Gold, the neon Cyberpunk, the deep ocean Abyssal Depths, and the molten Crimson Forge. GLOBAL RESONANCE LEADERBOARDS Compete against other Engineers worldwide Recall Gears:tracks not only your Max Yield (High Score) but also your Fastest Average Reaction Time (in milliseconds) across every game mode and difficulty level. Can you handle the pressure? Step up to the machine and ignite the engine!
