About this game

Procurement Auction Battle - shade the bid

The concept

In a sealed reverse auction the lowest qualifying bid wins. Your bid is your cost plus a margin (shade). More shade means more profit per win but a lower chance of winning at all.

How it works

Each round you face several rivals whose bids you cannot see. You win only if your bid beats every rival and the buyer’s reserve. Scouting narrows the uncertainty about rival bids.

Winning strategy

Shade to the point that maximises expected profit = P(win) × margin - usually a moderate markup, not the extremes. Scout when rival behaviour is noisy.

bid = cost × (1 + shade) ; win ⇔ bid ≤ min(rivals, reserve) ; E[π] = P(win) × (bid − cost)
