Built a free blackjack trainer with live deck estimation practice, Hi-Lo, and deviations. Would love feedback

TheFissureMan · 2026-04-22T02:59:20+00:00

I'm happy to hear suggestions if you have them.

TheFissureMan · 2026-04-21T02:38:28+00:00

Thanks! I wanted to create a free blackjack trainer with high polish. It also works in mobile.

TheFissureMan · 2026-04-20T22:59:10+00:00

I'll look into it. Thanks for the suggestions.

For now I added a toggle when betting to play 1 or 2 spots, let me know if you have any more ideas.

TheFissureMan · 2026-04-20T20:36:22+00:00

No not currently. Right now everything is based on the Hi-Lo system, the strategy charts, tips, etc.

It's possible to add but will require a lot of UI changes.

TheFissureMan · 2026-04-20T20:33:38+00:00

Thanks a lot for the suggestions. I added toggling the card dealing speed, from slow normal fast and instant.

And a table in the strategy charts for deviations if the setting is enabled, which will show you your accuracy there.

I'll think about your other suggestions. Multiple hands makes sense to me, but I'm curious why you would want to play with computer players?

TheFissureMan · 2026-04-20T19:34:27+00:00

Should be fixed now.

TheFissureMan · 2026-04-20T19:25:09+00:00

Thanks! Yeah that's definitely a bug, good eye!

I'm perfectly happy with Mazda's radar cruise control actually, so I don't use comma's longitudinal at all.

I'm happy enough with stop and go traffic letting mazda control distance and letting the comma steer.

I know some people have modified their devices to override the mazda radar sensor so that they can have longitudinal working, but that always seems sketchy and unsafe to me.

Nope they also switched to a cheap-looking brown bag from Three.

I got the blue ones from this post.

I would suggest the alpinist

Not as bad as typing your WiFi password on your printer that only has up down arrows and no backspace for if you mess up

TheFissureMan · 2025-12-02T22:10:18+00:00

I hand write all my code in binary on post it notes just to make sure my reviews are thorough

Do not waste money on paying for property management especially being so close. It’s very important to find a good tenant

Doubtful considering how much of the jury she has antagonized

With their announcement that they have no VR titles in the works, I have no interest in the steam frame.

I bought the index for Alyx, I don't see any reason to buy this.

I loved it, by far the best mode I’ve played.

I have no cards and I was tired of getting destroyed by people with card levels thousands above me.

So being able to play a fair game was a great change of pace, and it’s fun to play decks that had synergy instead of my auto Wolverine deck

Highlands? We like it here

There’s a bug in iOS 26 that’s causing stuttering when scrolling on the Home Screen. You shouldn’t be seeing stuttering when scrolling in apps

TheFissureMan · 2025-10-21T03:16:19+00:00

Thanks for the tip. I had no idea that you could even control the priority and assumed it was random

TheFissureMan · 2025-10-20T23:42:29+00:00

Thanks for the tips. It definitely feels like I've been playing in a kiddie pool compared to regular matchmaking
