About this app

No page, no cards — the canvas is the whole window with translucent HUD panels floating over it. Drag from empty space to fling a body in with velocity; every pair attracts under an inverse-square law and collisions merge inelastically with momentum conserved. Trail persistence, gravity strength and mass are live, and the readout tracks kinetic energy, escapes and merges.

Win rates and risk grades are computed by Masterboard from tracked trade outcomes after the strategy is assessed — not self-reported by sellers. Past performance does not guarantee future results.
