Ditch the popsicle sticks and boring digital spinners. RandomArena turns cold-calling, volunteer selection, and random project grading into an interactive game that focuses the room instantly.
Physics-driven gravity wheel of fortune. Competitors occupy perfectly proportioned wedges of a high-RPM spinning torus. True velocity decay guarantees organic suspense.
Whimsical, slapstick physics. Contestants are automatically assigned adorable animals who bump each other out of bounds in a glowing circular pasture arena while dodging randomized methane gas blasts.
No Student Logins, Ever
No student accounts, logins, or app downloads needed. Copy and paste your roster directly into the engine and spin.
Smartboard & Projector Optimized
Large, clear, high-contrast visual elements designed to scale sharply on classroom displays, projectors, or interactive whiteboards.
Transparent, Fair Selection
The engine runs on unpredictable physics interactions, not a hidden code block. Students see the physical collisions, ensuring total transparency and zero complaints of bias.
Deploy isolated WebGL graphics directly in your browser with zero subscription fees.
Ditch the static interfaces and list sheets. Run full 3D physics-based simulations on zero lag directly in your browser.
