Hey,

I am building a free blackjack trainer and wanted to share it:
https://blackjack-trainer-aj9.pages.dev/

I hope u guys find it useful if you are:

- learning basic strategy: it tracks your accuracy per hand and dealer upcard, so you know exactly which spots you're leaking on. Biased dealing means the hands you keep screwing up show up more often until you nail them. There are a bunch of apps like this but mine tells u your odds depending on the house rules and your precision with the strategy.

- start/practicing counting: Realistic shoe simulation (4/6/8 decks, configurable penetration), running + true count, Hi-Lo / KO / Hi-Opt I / Omega II, and a deviation chart that highlights which index plays are active based on your current count.

It's totally free, no login, no ads. Would love feedback from the community

Hey, I know there are a ton of these trainers out there but I built my own because I couldn't find one that showed me my actual win probability factoring in both the casino's house rules and how well I'm actually playing. Turns out if you're making mistakes on basic strategy you're giving away a surprising amount of edge on top of whatever the house already has.

Some things I ended up adding along the way:

You can change the house rules (decks, soft 17, DAS, surrender, 3:2 vs 6:5 payout) and the strategy tables and edge numbers update live. There are presets for common real casino configs too.

It also has biased dealing so hands you keep screwing up come up more often, and you can filter to just drill hard totals, soft hands, or pairs if you want to focus on something specific.

Threw in a fake betting system mostly for fun but it does settle doubles, splits and surrenders correctly so it's somewhat realistic.

Next thing I want to add is Hi-Lo counting training with running count, true count and deviation drills. That's actually the main reason I started building this instead of just using one of the existing ones.

Anyway curious what you all think, and if there's something you wish your trainer did that none of them do. Do you think a counting helper built into a trainer makes sense? Open to ideas on how to implement it too.
