Straight up: perfect basic strategy trims the house edge to about 0.5%. It does not beat the casino, and nothing does. What it guarantees is that you never make a play the math says is wrong.

Straight answers

Does this guarantee I'll win money?

No — and be wary of anything that claims it does. Perfect basic strategy trims the house edge to about 0.5%, meaning the casino still holds a small mathematical edge over the long run. BJAssist makes sure you never make a worse-than-optimal play. It does not, and cannot, flip the odds in your favor.

Does it play for me?

No. BJAssist is read-only. It shows the recommended move; you decide and click. It never automates play.

Is using a strategy helper allowed?

Basic-strategy advice is legal, but many casinos' Terms of Service restrict third-party software and on-screen assistants. Whether you use the on-page suggestion feature on a given site is your responsibility — check that site's terms. The free manual calculator sidesteps this entirely since it never reads any casino page.

Does card counting work here?

Not for online RNG blackjack. Those games reshuffle every hand, so there's no count to track. BJAssist is a basic-strategy tool, not a counting tool.

Where does my data go?

Nowhere. The engine runs entirely in your browser. No card data, credentials, or play history is sent to us.
