## What is Blackjack Guru?

Learn how to play Black Jack with BlackJack Guru!

Blackjack is a game of skill, where every decision moves the odds for or against you. Blackjack Guru helps you understand the strategy behind the game and build real confidence, without ever risking money.

Whether you're new or experienced, the trainer adapts to your level and takes you step by step. Learn the fundamentals, master basic strategy, then progress into card counting.

TRAIN

· Strategy Table: Learn the correct decision in every situation, at a glance.
· Strategy Drills: Play out simulated hands and decide whether to hit, stand, split, double, or surrender based on the dealer's upcard and your own.
· Instant Feedback: Find out immediately whether you made the optimal play, so mistakes turn into learning.
· Understand Why: Go beyond memorizing. Every decision comes with a clear explanation grounded in probability and outcomes.
· Multiple Training Modes: Focus on the hands you find hardest, such as pairs, soft hands, hard hands, or high-difficulty spots. Drill tricky situations until they're automatic.
· Smart Training Mode: Adapts to your play and targets your weak spots, repeating hands similar to the ones you got wrong so you actually learn before moving on.
· Adapts to Every Level: Whether you're learning the rules or refining an advanced game, difficulty and training order match your skill.

COUNT

· Card Counting Theory: Understand how counting works, step by step. The system, the card values, and how to keep an accurate running count.
· Card Counting Practice: Build speed and accuracy with structured exercises across multiple difficulty levels.
· Full-Table Counting: Train on multiple hands at once and keep the count under pressure.
· True Count and Deviations: Learn how the running count converts to a true count, and what changes when it does.

TRACK YOUR PROGRESS

Detailed statistics show your correct-decision rate over time, reveal patterns in your play, and point you to the areas worth working on next.

START PRACTICING TODAY

Blackjack Guru is built to teach you the game with data, not luck. Unlike typical card games, it focuses on the correct decision in every possible blackjack 21 scenario, and on the reasoning behind it, so you understand both the what and the why.

### 1/5 — Paid only

*2026-08-18, version 2.18.0*

Request for review comes before even using app.  Use 3 times, makes you pay.

### 1/5 — Account Management

*2026-07-29, version 2.16.2*

There's no way to manage your account / subscription from within the app.

### 2/5 — Too easy

*2026-07-13*

I hit the end in 1 hour as a beginner learning how to count. There is no real practic except just hit and stand. I wanted to learn how to implant the count into the sheet or play with like 1k chips and see how well I do with the new strategies I learnt. I just think there is so much room for improvement.

**Developer response:** Thanks for the detailed feedback. We are actively expanding that part of the app and we’ll add more modules in the near future. Glad you got through the basics quickly.

### 1/5 — membership cost

*2026-07-09, version 2.16.0*

Probably shouldn’t have a membership cost hidden behind a questionnaire. A free trial afterward subscription fees is a money grab. No thanks

### 5/5 — Amazing

*2026-07-08, version 2.16.0*

This app helps a lot

### 1/5 — These subscription based games suck

*2026-07-07, version 2.16.0*

Idk what’s going on, but now everyone and their mother wants you to sign up for some pointless subscription. You literally have to pay just to be told whether you’re right or wrong. Bro, just watch a YouTube video. This whole trend is dumb frfr. Yeah, I get that it’s supposed to “help you improve,” but come on… what are we even doing at this point.

### 3/5 — BRUU

*2026-06-30, version 2.14.0*

Good but the pay wall is annoying

### 1/5 — Sign up

*2026-06-19, version 2.13.0*

Once i signed up it didn’t let me cancel my membership. Tried emailing support but no response

### 5/5 — Great app

*2026-06-18*

These guys have the best blackjack training available

**Developer response:** Thanks a lot, that means a lot to us. Glad the training is landing. More card counting and strategy content is on the way!

### 1/5 — More levels are needed in module 2

*2026-06-12, version 2.13.0*

Bring back the bigger stacks on module 2 so that we can practice not losing the count at bigger stacks and make module 3 at pro speed faster
