Diable The Money Maker
If you only play online at the minimum stake of 1 credit per box, you will quickly recoup the cost of the subscription. DIABLE makes an average of 1% per hand.
You can play with basic strategy, with many blackjack sites giving wonderful colored charts to assist you and that is indeed better than guesswork. However, unless you are counting, then you will lose 0.5% per hand.
DIABLE calculates exactly taking into account all the cards on the table, and all the cards that have been dealt in previous hands in a shoe game. It knows the rules perfectly and plays perfectly. Far better than counting and indexes.
You can enter your bankroll into DIABLE and it will tell you the stake in advance, calculating the chance of every two-card combination taking into account the composition of the remaining cards in the shoe.
You can set the “spread”, based on your percentage expectancy on the next hand. Typically this is only 1, 2, 3, 4 and 5, with the last two being very rare. If it thinks you should bet zero, it will tell you to bet zero, although you can set it so that you bet one unit every hand or only miss, say, 5 hands without betting.
You can play for “monopoly money” against DIABLE without staking a penny, and if you intend to play in “land-based” casinos this is a great way to improve. You can download a spreadsheet report with all the hands you play in a session and it will tell you of your staking and play errors.
- There are many variants of Blackjack, and many side bets. If you find one we haven’t covered yet, we will analyse and add it as soon as we can.
There are many online Blackjack sites. If you are stopped from playing on any site – with a small advantage of 1%, you usually stay under the radar – just move on to another reputable site. Always follow the casino’s rules regarding software use, or proceed at your own risk.

The strength of Diable is proven in real gameplay situations. For example, when facing a tricky hand, most players might follow basic strategy, but Diable goes deeper—calculating precise equity for every possible move. This ensures that every hit, stand, double, or split is the mathematically best choice, maximizing long-term profit.

We’ve Got the Power
The power of the program is shown by this hand, played on the Microgaming site. The player had K7 against a 9, and basic strategy is to stand, but it correctly hits here, with an equity of -0.4543, which is better than standing with an equity of -0.4691.
