About FreeBlindBox.com

FreeBlindBox.com was created by arcade hardware enthusiasts and vinyl art toy collectors to solve two common frustrations: opaque claw machine mechanics and scattered image-only collector checklists.

Our browser-based Online Claw Machine Simulator uses a 60fps damped spring pendulum integrator, real-time Center of Gravity (CoG) offsets, and a procedural CC0 Web Audio DSP synthesizer so players can practice 180ms Double-Drop timing and Japanese 2-prong UFO Catcher edge hooks at zero cost.

Alongside our arcade cabinets, we maintain an interactive 138-Figure Smiski Checklist across all 16 official series plus trackers for Sonny Angel, Skullpanda, Hirono, Dimoo, and Labubu, complete with 0.1g box weight hints and instant A4/Letter printable PDF and CSV exports.
