Introduction
Omega II, developed by Bryce Carlson in Blackjack for Blood, is a Level 2 balanced counting system. It assigns values of +2, +1, 0, -1, and -2 to different card ranks, creating a more precise picture of the remaining deck composition than any Level 1 system can achieve.
The cost? More mental effort. But for experienced counters who’ve maximized what Hi-Lo offers, Omega II unlocks an additional edge.
Card Values
| Card | Omega II Value | Hi-Lo Value | Notes |
|---|---|---|---|
| 2 | +1 | +1 | Same |
| 3 | +1 | +1 | Same |
| 4 | +2 | +1 | Upgraded |
| 5 | +2 | +1 | Upgraded |
| 6 | +2 | +1 | Upgraded |
| 7 | +1 | 0 | Changed |
| 8 | 0 | 0 | Same |
| 9 | -1 | 0 | Changed |
| 10 | -2 | -1 | Upgraded |
| J | -2 | -1 | Upgraded |
| Q | -2 | -1 | Upgraded |
| K | -2 | -1 | Upgraded |
| A | 0 | -1 | Changed |
Seven ranks differ from Hi-Lo. The key changes:
- 4, 5, 6 → +2: These are the most impactful low cards. When removed from the deck, they shift the odds more than 2s or 3s.
- 10-K → -2: Similarly, 10-value cards have the largest impact among high cards.
- 7 → +1: Like KO, the 7 is counted.
- 9 → -1: The 9 gains a negative value — it’s a borderline high card in terms of deck impact.
- A → 0: Aces are neutral in the main count (requires side count).
Why Multi-Level Values?
In Hi-Lo, a 5 and a 2 are worth the same (+1 each). But mathematically, the 5 has a much larger impact on the player’s edge when removed from the deck. By assigning +2 to the 5 (and 4, 6), Omega II weights the count according to actual mathematical impact.
Similarly, a 10 matters more than a 9 for the player’s advantage. Omega II captures this by giving 10s -2 and 9s -1.
The result: betting correlation of 0.92 — meaning the count more precisely tracks when you have a betting advantage.
Verification: It’s Balanced
Let’s verify Omega II sums to 0 across a full deck:
- Four 2s: 4 × (+1) = +4
- Four 3s: 4 × (+1) = +4
- Four 4s: 4 × (+2) = +8
- Four 5s: 4 × (+2) = +8
- Four 6s: 4 × (+2) = +8
- Four 7s: 4 × (+1) = +4
- Four 8s: 4 × (0) = 0
- Four 9s: 4 × (-1) = -4
- Sixteen 10-K: 16 × (-2) = -32
- Four As: 4 × (0) = 0
Total: +4 +4 +8 +8 +8 +4 +0 -4 -32 +0 = 0
Confirmed balanced. The deck countdown drill will still end at 0.
Worked Example
4♦, K♠, 9♣, 5♥, 7♦, A♣, 10♥, 3♠, 6♣, 8♦
| Card | Value | Running Total |
|---|---|---|
| 4♦ | +2 | +2 |
| K♠ | -2 | 0 |
| 9♣ | -1 | -1 |
| 5♥ | +2 | +1 |
| 7♦ | +1 | +2 |
| A♣ | 0 | +2 |
| 10♥ | -2 | 0 |
| 3♠ | +1 | +1 |
| 6♣ | +2 | +3 |
| 8♦ | 0 | +3 |
Compare with Hi-Lo for the same sequence: (+1)+(-1)+(0)+(+1)+(0)+(-1)+(-1)+(+1)+(+1)+(0) = +1
Omega II’s count of +3 gives a stronger signal because it weights the impactful cards more heavily.
The Ace Side Count
Like Hi-Opt I, Omega II treats Aces as neutral. You need a separate ace side count:
- Track total Aces seen
- Compare to expected (4 per deck × number of decks)
- Ace-rich remaining shoe → increase bets beyond what the main count suggests
- Ace-poor remaining shoe → temper your bets
Practice Exercises
Sequence 1: 5♣, 10♦, 4♥, Q♠, 6♣
Answer
(+2) + (-2) + (+2) + (-2) + (+2) = +2
Hi-Lo: (+1) + (-1) + (+1) + (-1) + (+1) = +1
Sequence 2: 9♥, 7♠, A♦, 3♣, K♥, 5♦, 8♣
Answer
(-1) + (+1) + (0) + (+1) + (-2) + (+2) + (0) = +1 (Aces seen: 1)
When to Use Omega II
Choose Omega II if:
- You’ve mastered a Level 1 system and want more precision
- You can handle +2/-2 mental arithmetic at speed
- You’re comfortable maintaining an ace side count
- You primarily benefit from better bet sizing (high BC)
Consider Zen Count instead if:
- You want multi-level accuracy but don’t want an ace side count
- Zen Count includes Aces at -1, eliminating the side count burden
Key Takeaways
- Omega II uses 5 value levels: +2, +1, 0, -1, -2
- 4/5/6 = +2 and 10-K = -2 reflect their actual mathematical impact
- Highest practical betting correlation (0.92)
- Requires an ace side count (Aces are neutral)
- The system is balanced — full deck sums to 0
- Only recommended after mastering a Level 1 system
Next Steps
If the ace side count feels like too much overhead, try the Zen Count — it offers similar multi-level precision while counting Aces in the main count. Or return to the counting systems comparison.
