eFootball DB / Pack simulator

Pack opening simulator

A fresh box. Real cards. Your next opening.

How the eFootball pack simulator works

Open one card or ten

Choose a pack to build a 150-card simulated box. Open one card or ten at a time, review your opening history, and track simulated coins spent. Skip the animation to see the same committed results immediately. Reset restores the original box and clears this session’s history and spending.

How pack odds change

Every remaining card has an equal chance, and drawn cards are removed. The odds calculator shows your chance of obtaining one specific featured card or at least one featured card within your next chosen number of draws. After a reveal, it recalculates from the remaining box. These probabilities describe this simulator and do not predict real eFootball openings.

Which cards fill the box?

The selected pack’s top three database cards are the featured targets, or fewer if the pack has fewer linked cards. Distinct lower-rated Standard, Highlight and Trending catalogue cards fill the remaining slots. Featured card IDs are excluded from fillers. This added roster is simulated, not a verified official pack list.

Simulated roster

About this simulation

The filler roster is simulated, not the verified official pack composition. Featured targets are the top three cards in the selected pack’s database ranking. Packs with fewer than three linked cards use the cards available. Box size, odds and prices are simulation assumptions; these openings do not predict game results.

Configured simulation prices: 100 coins for one and 900 coins for ten. Reset clears spending and history.

Filler policy and probability model

Policy v1: choose rated Standard, Highlight and Trending catalogue cards, exclude featured card IDs, deduplicate by card ID, sort by displayed rating (max rating, otherwise base rating) ascending, then by ordinal card ID. Take enough to reach exactly 150. Different versions of the same footballer may appear. Unknown ratings are excluded. The roster is fixed for this session; database changes may change a later session.

For R remaining cards, K remaining featured cards and N future draws: specific remaining card = N/R; at least one featured = 1 − C(R−K,N)/C(R,N). Already drawn targets have zero future probability. Random indices use browser crypto with rejection sampling.
