Blackjack Card Counting Systems: Hi-Lo, Hi-Opt, Omega II, Wong Halves

The industry standard balanced count. Best first system — strong betting power, simple tags, and true-count conversion.

Unbalanced count that skips true-count math. Ideal if you want solid results without dividing by decks remaining.

Highly optimized level-1 system with superior playing efficiency. Ace-neutral running count plus optional side count.

Level-2 refinement with richer tags. Excellent playing efficiency for players ready to track multi-value counts.

Powerful multi-level balanced count with outstanding betting and playing strength when paired with an ace side count.

Fractional multi-level system with near-theoretical betting correlation. Maximum power for dedicated counters.
