Dominion · Opening Simulator

Monte Carlo simulation of 3/4 and 4/3 openings (5/2 splits are rerolled and excluded). Success = a hand reaching the target $ on turn 3 or 4. Buys go to the discard pile; the full deck is reshuffled before turn 3. Opening buys are planned across both turns (T2 money is known: $7 minus T1). When Secret Cave is in the opening, one starting Copper is replaced by its heirloom, Magic Lamp.

Notes: on a 3/4 opening only one of turns 1/2 has $4. With Alms the $3 turn can gain a card costing up to $4; with Amass either turn can gain an Action costing up to $5 (5-costs like Baker are otherwise unbuyable in the opening). Terminals (Baron, Smithy) are limited to one play per turn.
