Gravity Physics vs ScaleIt

Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES • Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth • True N-body gravity — every body pulls on every other body and on your ship, in real time • Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn • Time controls — speed up months of orbital motion or slow down to precision-dock in real time • Trajectory prediction — see where your current heading will take you before you commit • Flight trail — trace your path across millions of kilometers • Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.

Step into a tactile world of visual estimation games and scale comparison challenges designed to test your spatial intuition. ScaleIt combines a charming ink-and-paper sketchbook aesthetic with precision size-guessing puzzles. Compare a reference object with a target object, adjust its proportions, and lock in your estimate against the real world. Whether you are evaluating microscopic viruses, everyday household items, massive architectural landmarks, or colossal cosmic entities, every session puts your perception to the test across five fast-paced rounds. KEY GAME FEATURES • Five-Round Sessions: Complete structured visual estimation challenges featuring symmetric accuracy scoring and a classic 0-100 log score bar. • Cinematic Morph Reveal: Experience a smooth, satisfying scale transition when locking in your guess to see your error margin close or expand. • Streak & 2-Strike System: Maintain your momentum with a balanced 2-strike safety net that rewards consistent accuracy. • Field Archives (Discovery Notebook): Unlock discovered objects permanently, explore authentic real sizes, and learn fascinating educational facts like a true field researcher. • Massive Scale Spectrum: Encounter subjects spanning from nanoscopic elements and insects to towering skyscrapers, planets, and deep space structures. • Tactile Audio & Haptics: Fine-tune your immersive preferences with custom sound effects and haptic responses tailored to file-and-pen aesthetics. • Multilingual Localization: Play natively in English, Turkish, German, French, Italian, Japanese, Korean, Russian, Swedish, and Portuguese. FLEXIBLE PLAY & FAIR MONETIZATION • No Account Required: Jump straight into the action instantly with zero registration or logins needed. • Daily Tickets: Enjoy three free daily session tickets that automatically renew at local midnight. • Optional Rewarded Ads: Free users can view optional ads to earn an extra daily ticket when needed, alongside standard home-screen banner ads. • Lifetime PRO Upgrade: For players seeking a completely uninterrupted experience, an optional one-time lifetime PRO purchase unlocks unlimited session play and removes all advertisements entirely. Put your intuition to the test and discover how well you truly understand the scale of the world around you.
