Clatter is the dice roller built for players who actually care. Full 3D physics. Metal-shaded premium dice. A nat 20 that earns its celebration. THE ROLL Every die in Clatter obeys real physics - it bounces, tumbles, and settles against the table before revealing its result. No animations on repeat. No pre-baked outcomes. 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. These reactions exist because high-stakes rolls deserve a response that matches the moment. THE FEEL Haptic feedback on every impact, settle, and result. Sound design built around real dice - impacts, tumbles, reveals - mixing seamlessly with your music. Respects your silent switch. Everything can be toggled.

Your rolls stay on your device.
