Original Plinko

Original Plinko uses a deterministic physics core written in C++ and exposed to Lua for rapid tweaking. Each frame simulates:

1. Gravity application (g = 9.81 m/s² adjusted for pixel units).
2. Elastic collision with pegs (coefficient = 0.83).
3. Chip deformation to avoid jitter (bite‑size Verlet adjustment).
4. RNG seed salt injection every 32 frames to guarantee unpredictability while staying verifiable.

// simplified pseudo‑code
for frame in GameLoop do
  chip.vy += gravity * dt
  chip.y  += chip.vy * dt
  if pegCollision(chip) then
    chip.vx = -chip.vx * 0.83
    chip.vy = -chip.vy * 0.83
  end
end

All random offsets are signed with the server seed. Players can verify fairness by combining the revealed seed with their client hash post‑game.
