Expert Advice: Start by learning the moves for hard totals 12–16 versus dealer 2–6. These situations happen often and impact your results most significantly.

Grasping Likelihood

🎴

Likelihood Fundamentals

Blackjack outcomes adhere to predictable statistical patterns. Key information:

Regular deck has 52 cards
Every rank shows up four times
16 cards equal 10 points (10, J, Q, K)
Chance of pulling a 10-value card: 16/52 ≈ 30.8%

This clarifies why a dealer's 7, 10, or Ace is viewed as "powerful" — their chance of creating a strong hand increases significantly.

🏛️

Comprehending the House Advantage

Even if you choose the best move consistently, the house still holds a small statistical advantage:

Flawless fundamental tactics: ~0.5% house advantage
Haphazard or "intuitive" play: ~2–3% house advantage
Possible savings per $1000 wagered with proper tactics: $15–$25

📉

Expected Return (EV)

Every blackjack choice has an EV — the average result over many repeated trials.

Example: 16 vs Dealer 10

Hit on 16:

P(reaching 17–21): 38%
P(busting): 62%
EV: -0.54 units

Stand on 16:

P(winning): 23%
P(losing): 77%
EV: -0.54 units

Both moves are equally poor — which clarifies why 16 vs 10 ranks among blackjack's toughest situations.

Behind the Scenes: How Our WASM Architecture Functions

arcaneleague.org is built for transparency. Here's what powers each simulation.

🎴

Equitable Shuffle Method

We employ the Fisher–Yates shuffle, a statistically validated technique for authentic randomness:

Begin with a sorted deck
For every card from back to front:
- Choose a random location
- Exchange cards
The outcome: completely uniform randomness

This method is common in professional digital card games and ensures authentic equity.

🚀

Why WebAssembly?

Most browser games rely on JavaScript. Our architecture is compiled to WebAssembly (WASM), offering:

2–20× quicker performance than JavaScript
Steady 60 FPS on newer and older hardware
Reduced file size for quicker loading
Functions offline after initial load
Transparent, inspectable Rust source code

🔒

Verifiably Equitable System

Each shuffle and hand outcome is produced using a deterministic, verifiable procedure:

Cryptographically secure random number generator
Shuffle occurs before gameplay begins
No "manipulated" results — mathematics only

Because the algorithm is transparent and inspectable, results cannot be modified in any way.
