Theory
Perfect Book House Edge
If you follow basic strategy perfectly in this ruleset, the long-run house edge is about 0.46%. That means expected player return (RTP) is about 99.54%.
Method
Book Assumptions
Blackjack Strategy Coach uses a fixed basic-strategy baseline for 4-deck blackjack where the dealer stands on soft 17. No surrender or insurance is modeled.
Recommendations are generated from pair, soft-total, and hard-total strategy matrices, then adjusted if table constraints make the preferred action illegal.
Split and double availability depends on hand composition, bankroll constraints, and table limits. All feedback compares your selected action against the matrix recommendation for the exact state.
What This Means In Practice
House edge: 0.46%
Player RTP: 99.54%
Expected loss per $100 wagered: $0.46
Short-term results can still swing heavily due to variance.
