JupiDemonChimp Playground is a free multi-ball physics browser game. Every ball has its own randomised mass and elasticity — heavier balls are slightly larger and barge lighter ones aside in real mass-aware elastic collisions, wobbling on each hit (bouncier balls ring harder). Every ball also has a fragility: light, fragile balls shatter after a few knocks into ever-smaller shards (heavy balls resist far longer, solid ones never break) — so a calm scene can chain-react into a swarm. Because real elastic collisions slowly bleed energy, a surprise shockwave periodically pulses through to re-energise everything (hit 💥 Shock to trigger one yourself) — the breaking never grinds to a halt. Turn up Attract and the balls pull on each other with real Newtonian gravity (force ∝ mass₁·mass₂ ÷ distance²) — set it to zero for none, or higher to watch them clump into orbiting clusters. Drag the Balls slider for 1–20 balls, Gravity to drop them, Fragility to make breaking rarer or constant, and Speed to change pace. Click the canvas (or press space) to pause; hit reset to reshuffle. No goal, no scoreboard — just clean physics in your browser. Part of the Gazillion Dogs free browser games collection. Works on phones, tablets, and computers.
