Common questions

A few straightforward answers. Community chat and forums are coming soon.

How does this actually help my EV in the real world? ➜
The biggest EV leaks are usually game selection and under/over-betting. The casino map cuts down time wasted on marginal games, and the bankroll tools help you pick spreads that match your risk tolerance instead of guessing.
Can this help me handle ugly variance and big downswings? ➜
Variance doesn’t go away, but you can choose how aggressive your plan is. The bankroll tools let you compare different spreads and see how risk changes so you can pick something you’ll actually stick to when things run cold.
Will this stop me wasting trips on bad or dead games? ➜
No tool can fix every casino, but the map highlights rules, pen and mins so you can quickly see which rooms are worth scouting and which ones you can skip.
Is this a training site with courses and videos? ➜
No. It’s a toolkit: maps, bankroll, practice, and tracking. If you already know the basics, these help with planning and consistency.
What about cost and privacy? ➜
There’s no trial and no paid tier being hidden behind this page. It’s free because we believe in open source and freedom of information. No credit card required. We don’t sell your data.
What’s the catch? ➜
No catch. Use it without a card, without a trial, and judge it by whether it helps. If it doesn’t, you can ignore it.
What’s coming next? ➜
A dedicated community chat app and forums are coming soon — a simple place to share notes, trip planning, and progress without the noise.
