Dinsun Expert Review

Our Expert Score

84/100

Blackjack Teacher Pro is an indispensable tool for anyone serious about improving their casino play. It’s less of a game and more of a high-performance training simulator. The 'Smart Training' mode is particularly impressive, as it recognizes which specific hand combinations you struggle with—like those tricky soft 17s—and drills you on them until you've mastered the optimal move.

The level of customization is what makes this a 'Pro' app. You can choose from nearly a dozen different card counting systems, from Hi-Lo to Zen, and even customize the bet charts to match the specific rules of your local casino. If you want to stop gambling and start playing with a statistical edge, this is the most comprehensive trainer on the market.

Cards are Random from a Shoe
Thu Jul 23 2009 GameDev-PepperDogSoft

To the previous reviewer, the cards are drawn from a randomly generated shoe based on the number of decks set in the configuration screen. If you are using Targeted training then yes it is random and the trainer tells you this when you start up the training mode. So before you post a review please know the facts.

Needs counting drill tweak
Wed Jul 07 2010 Jeffj2h

This is an excellent Basic Strategy drill and counting drill program. I use a slightly modified KO count and I was able to adjust the index values and Initial Running Count in the app. I have no complaint on the Basic Strategy drill. I believe the counting drill needs a tweak: allow the user to see a programmable number of cards (e.g. 10) then ask "what is the count?". Also allow the user to program how fast those 10 cards will flash on the screen and if the user wants 1 card to flash at a time or 2 cards at a time. That better simulates what happens when a dealer deals hands to a table and the player has to quickly scan a lot of cards. Currently the program shows a player hand and dealer up card and asks "what is the count?". Then repeats. However I would say the programmers know a lot about Blackjack, as seen in the configurability of this program. Great job.

Almost Perfect

Very nice! Would be the ultimate except for two things I've noticed: (1) True count divides by full decks. It needs to have the option to calculate true count by dividing by the number of half decks left (i.e. with 6 decks remaining, divide by 12, with 5 and a half decks left, divide by 11, etc.). I play a strategy that uses this method so without this option, I can only use this app to practice counting. Practicing betting and playing strategy are useless which means I can only practice 1 of the 3 elements of counting; (2) In the action menu, there needs to be a stand/hit option. If there is one, I can't find it. This is used for every player hand 12-16 against any dealer card 2-6 and a few other places. If these changes are made, I would give this app a big 5 stars!

Needs focused practice sessions
Thu Jul 29 2010 ksitze

This is a great card counting app, there are numerous enhancements I would love to see. (1) keep timing statistics on each triplet so the player can determine which hands they're bogging down on (2) keep good/bad/timing statistics across sessions (overall statistics) and allow user to track how they're improving on problem hands (3) add a drill mode for basic strategy, many triplets come up infrequently using a normal shuffled deck so add a mode that drills on learning the basic strategy by displaying random triplets (yes, card counting at this level is useless, but for a beginner, attempting to count the cards is useless anyway until the basic strategy is nailed) (4) modify drills to increase probability of displaying triplets where there are problem areas (5) allow multi-card drills rather than just triplet drills, this is true for both basic strategy and card counting that player will have more than two cards played out once they hit/split and correct strategy requires knowing the secondary plays after a successful hit. Thanks for the great app, and I hope to see more of these features going forward.

Nice update

I've had requested the true count variation awhile back and had been waiting on this update. Now I can lock in my system for practice. Hopefully we'll be seeing it added to Multihand Blackjack soon too.

Great app but calculates true count incorrectly
Thu Aug 19 2010 1001111010101

Overall the app is great. My only major concern is that the true count (TC) is calculated incorrectly. For example when the count is +9 and there are 20 cards remaining (~.5 decks) the TC should be 9/.5=18. Instead the app shows TC= 6. TC should be equal to the count divided by the number of decks remaining rounded to the nearest quarter for 2 deck or fewer games. This would be a five star app if not for this error.

Another great 21 app from PepperDogSoft
Mon Jan 09 2012 CarmineD

Would love to see this app offer additional counting drills of a single card and two cards (like Casino Verite), in addition to the sole 4-card layout of you vs. the dealer. Otherwise, another very nice app from this developer.

Good when it works
Tue May 12 2009 Tcheat

Crashes constantly. Works well when it works, but needs bugs worked out. Also, for counting, it would be great to deal multiple hands and simulate a casino experience.
