Blackjack software covers several kinds of work: calculating one hand, simulating millions of rounds, training a count, or recording the cards of a shoe as it is dealt. Tools with similar names can do different things. A "calculator" can mean a single-hand analysis or a bankroll-risk estimate. "Bet sizing" can mean an optimised bet spread from a simulation, or a fixed rule applied to the next round.
This page sets three alternatives next to OddsOfBlackjack (OOB), using the same criteria for each. It describes what each product states about itself on the pages consulted. It does not rank them. Which tool fits depends on the question you want answered.
The three alternatives were chosen because they serve players who already know basic strategy and a counting system such as Hi-Lo:
| OddsOfBlackjack (published) | Wizard of Odds Hand Calculator | CVCX (QFIT) | Blackjack Apprenticeship | |
|---|---|---|---|---|
| Purpose | Decision support for the current state of a shoe: the calculated EV of the available actions from the cards and table rules you enter, and a suggested initial bet under a published rule | "The best return for a blackjack hand": the best play and the expected value of each option for one hand, as the publisher describes it | A simulator and calculators for comparing games and strategies, optimal bets and bankroll risk. The vendor says it is based on Blackjack Attack by D. Schlesinger | A card-counting training membership: video course, training suite, community. Depending on the plan, it also includes tools for bet sizing and results tracking |
| Rules accepted | 4, 5, 6 or 8 decks. Dealer stands or hits soft 17. US peek or ENHC. Double on any two cards, 9–11 or 10–11. Double after split yes/no. Split to 2, 3 or 4 hands. Resplit aces yes/no. Hit split aces yes/no. Surrender none or late. Blackjack pays 3:2 or 6:5 | 1 to 8 decks. Blackjack pays 3:2, 7:5, 6:5 or 1:1. US peek or ENHC. Soft 17 stand/hit.

Surrender not allowed, allowed against any card, or allowed against any card except an ace | Deck counts 1, 2, 4, 6 and 8. "Multiple rule combinations"; the product page does not list them | Not listed on the pages consulted. The Pro Betting Software is described as simulating "exact game conditions" |
| Inputs | The table rules. Each exposed card by rank, with one button for all ten-value cards, assigned to your hand, the dealer, or other exposed cards. The balance you confirm and the bet rule (Graduated or Selective) | The rules, the deck count and the shoe composition by rank (2 to 9, tens, aces). Your cards and the dealer's up card, as the publisher describes it | Strategy and counting system, decks, rules, penetration, bet spread, risk and bankroll | Your answers in the training drills (counting, deviations, true count conversion, betting). The game conditions you set in the Pro Betting Software. Your session data in the Results Tracker |
| Results shown | The calculated EV of Hit, Stand, Double, Split and Surrender when available, per original bet. The action with the highest calculated EV. A pre-bet EV estimate. The Hi-Lo True Count, for reference. A suggested initial bet, fixed for the round. A saved history of your session entries. OOB does not calculate risk of ruin or variance for your play | The best play and the expected value of each option, as the publisher describes it. The page text does not list which actions are shown | Win rate, expectation and SCORE. Optimal betting ramps. Risk of ruin, probability of reaching a goal, required bankroll and range of probable results | Training feedback. Pro Betting Software: optimised bet spreads and their impact on risk, EV and bankroll requirements. Results Tracker: profit, actual value, hours and expenses, with solo and team bankrolls and custom fields |
| Devices | A web browser. Pages adapt to desktop, tablet and phone widths | A web page | Windows software. QFIT has also announced an experimental CVCX Online that runs in a browser with part of the functionality; its current availability was not tested | Web-based training drills. Pro Betting Software "from any device with a browser". A Card Counting Trainer app for iOS and Android |
| Access | A user account with valid access. Free trial access is requested, reviewed and activated manually; no card is required, and the trial does not turn into a paid plan | Free; the page states no account requirement | A paid licence, delivered by download, or shipped on request. A demo is available. One copy in use at a time | A paid membership in three plans: Starter, Apprentice and Elite. Pro Betting Software and Results Tracking Software are listed in Apprentice and Elite. Some training drills are public. 14-day money-back guarantee |
| Price | Free trial available by request; no card required. OOB paid-plan prices are outside the scope of this comparison | Free, as the publisher describes it | CVCX V6 is listed at $125 on QFIT's order page, which does not name the currency. An older CVCX product page, describing Version 3, mentions $75 | First year: Starter $397, Apprentice $597, Elite $997 (USD, as shown on BJA's store). All plans renew at $299 per year after the first year. Card Counting Trainer app: $4.99 |
One hand or a whole shoe. The Wizard of Odds calculator analyses the hand you describe, using the shoe composition you type in. OOB keeps a running record: each card you enter updates the remaining composition, and the action EVs update for the active hand. These are different workflows for a similar calculation. The two tools also offer different rule sets: deck counts, payouts and surrender options differ. A setting with the same name is not necessarily the same rule.
Analysing a game or analysing a decision. CVCX and BJA's Pro Betting Software evaluate game conditions and bet spreads, and report measures such as risk, EV and bankroll requirements. OOB does not estimate risk for your play. Its published simulations use a fixed unit and are documented separately on the Proof page. OOB evaluates the decisions of the state you record and suggests an initial bet under one of two published rules. These tools answer different questions and can serve different stages of preparation.
Learning or calculating. Blackjack Apprenticeship trains a counting method through a course, drills and a community, and includes planning and tracking tools in some plans. OOB is not a counting trainer and has no drills. It shows the Hi-Lo True Count only as a reference beside its own calculation. OOB's Learn pages explain the concepts and can be read without an account.
What this comparison does not establish. It covers only what the pages consulted state. A feature not mentioned there may still exist, and an identical workflow in another product was not tested. No product was bought, installed or run for this page.
Shared limits. Every tool here depends on its inputs and its model. OOB's results depend on entering the cards and the rules correctly. A highest-EV action can still lose, and Expected Value describes mathematical expectation, not guaranteed results. Neither this page nor OOB promises winnings.
Where you use software matters. Laws and venue rules about electronic devices at gaming tables differ. For example, Nevada's NRS 465.075 prohibits using, or possessing with intent to use, a device or software designed or programmed to obtain an advantage at playing a game in a licensed gaming establishment. The prohibition does not cover devices that are part of an approved game or otherwise permitted by the Nevada Gaming Commission. This page is not legal advice. Check the rules that apply where you are.
