The roll is real every time. Roll advantage and disadvantage natively. Set a difficulty check and get an instant verdict. Build compound expressions like 2d6+1d8+4 with the expression builder. Save your most-used rolls to Quick for one-tap access. Review your session in History and reroll anything instantly. THE DICE Standard sets - Classic Red and Classic Black - are included free. Unlock premium dice crafted with custom Metal shaders: - Rose Gold: brushed anisotropic metal with dynamic shimmer - Moonstone: translucent with drifting adularescence and inner glow - Frozen: frosted ice with refractive cracks and internal blue light - Ember: molten core, charred obsidian shell, glowing magma fissures - Jade: deep translucent green with organic veining These are not texture swaps. Each set is a distinct material simulation. THE MOMENTS Natural 20: golden light floods the table. Sparkles cascade. Your phone rumbles. Natural 1: the scene darkens. A low pulse. Silence.

SkyStop Flight Hedge Simulator

Read full description

SkyStop is a flight disruption prediction market โ€” and this is the simulator. Practice hedging your flights against delays and cancellations using real flight data and virtual currency. No real money is involved. No purchases required. Just a free, accurate simulation of exactly how the live SkyStop platform will work. HOW IT WORKS Search any flight by route or flight number. SkyStop pulls live flight data and shows you the disruption probability for that specific flight based on 56+ million historical flight records. Choose your protection tier: - 15+ minutes late โ€” ~28% probability, 3.32x simulated payout - 30+ minutes late โ€” ~19% probability, 4.87x simulated payout - 60+ minutes late โ€” ~11% probability, 8.12x simulated payout - 120+ minutes late โ€” ~5% probability, 17.4x simulated payout - Cancelled โ€” ~4% probability, 23.57x simulated payout Enter your virtual stake. See your potential simulated payout instantly. When your flight lands, SkyStop checks the real outcome automatically. If your flight hit the threshold you selected, your virtual payout is credited immediately โ€” no paperwork, no claims, no waiting. WHAT MAKES SKYSTOP DIFFERENT Most travel protection requires you to file a claim, wait weeks, and hope the airline report says the right thing. SkyStop is built differently โ€” it's a prediction market, not insurance. Payouts are automatic, predetermined, and triggered by real flight data. No fine print. No exclusions. No adjuster. The rules are written before you board. POWERED BY REAL DATA Odds are calculated from 56+ million US flight records across hundreds of airports. Disruption probabilities reflect actual historical performance by route, airline, departure airport, and time of day. The same model that powers the simulator will power the live platform. SIMULATION MODE SkyStop is currently in Simulation Mode. All positions use virtual currency with no real-world value. No real money is accepted, held, or paid out. This app is a free educational tool that demonstrates how the live SkyStop platform will operate. The live platform โ€” with real hedges, real payouts, and full regulatory compliance โ€” is coming soon. Join the waitlist at skystop.app to be notified at launch. FEATURES - Search any US flight by route or flight number - Real-time disruption probability powered by historical data - Five protection tiers from 15-minute delay to full cancellation - Automatic virtual settlement based on real flight outcomes - Portfolio tracker showing all active and resolved positions - No purchases, no real money, no risk JOIN THE WAITLIST Early adopters on the waitlist qualify for bonus credits on their first real hedge when the live platform launches.
