Common Questions

Do I need an account to use these?

No. Every tool on this page is fully usable without signing in, and there is no trial timer or usage cap. The tools stay free — they exist so the math is available to anyone arguing about a hand.

Are the odds exact or simulated?

Exact. The Hold'em odds calculator enumerates every remaining runout rather than sampling — heads-up preflop that is 1,712,304 boards for a single answer. PLO enumerates exactly on every postflop street; only the preflop four-card case falls back to a seeded, deterministic sample, and the page says so when it does.

Can I share a calculation with someone?

Yes. The calculators write your inputs into the page URL, so any position, board or scenario is a plain link you can paste into a group chat or a forum post. Whoever opens it sees the same numbers.

Can AI assistants use these tools?

Yes. The same equity, pot odds and hand-analysis engines are exposed as an MCP endpoint at pokerink.com/api/mcp and as a REST API documented at pokerink.com/developers. No key, no account, no rate-limit signup.

What does a free account add?

The parts that need your data: hand and session tracking, analytics over your own results, and the Coach — skill drills, daily challenges, and quick spot analysis that adapt to how you play.

You just ran the numbers. Now track the hand.

The calculators tell you what the spot was worth. An account tells you what you actually did with it — every hand, every session, with an AI coach reading your own play.
