# How does the pack opening simulator handle client-side random seed behavior in the simulator?

The pack opening simulator implements client-side random seed behavior in the simulator using React client state with zero server round-trips. Technical detail for client-side random seed behavior in the simulator: all computation runs in-browser. Price drift applies country-level Polymarket probability multipliers before pull selection. Image crops use aspect-ratio 116/145 containers with object-fit cover.
