01 / Enough evidence
One bad hand is not a leak
Royalgrind waits for enough similar decisions and shows how confident it is before calling something a pattern.
The product
A study routine built from the way you actually play.
Royalgrind reads completed hand histories, finds decisions that repeat, and turns them into a review small enough to do before your next session.
What it does differently
Find the pattern.
Show the reason.
Check it again.
02 / Useful order
The expensive habits go first
Patterns are ranked by likely impact and evidence, not by whichever statistic looks most dramatic.
03 / Visible sources
Advice says where it came from
Solver references, mathematical models, and approximate guidance are labeled instead of blended into one confident answer.
04 / A next action
Every finding leads somewhere
Open the key hands, ask a question, or practice a few related decisions. No endless report to admire and forget.
05 / Follow-up
The next session closes the loop
New hands update the same pattern, so you can see whether study changed how you play—not just what you know.
What you get
A complete review loop.
Nothing to babysit.
Import the session once. Royalgrind carries the useful context from finding to explanation, practice, and follow-up.
Explore every feature01
A leak list you can finish

Your hands, not generic advice
02
Hand review with receipts
Replay the action, see the assumptions, and know when guidance is solver-backed or approximate.
Sources stay visible
03
A coach that knows the hand
Ask a normal question. Get an answer that uses the action, stack depth, ranges, and your history.
No prompt-writing required
04
Practice from your mistakes
Turn a finding into a small set of related decisions instead of browsing an endless spot library.
Short, targeted repetitions
05
Tournament context included
Review bubble and final-table spots with payouts in view, where chip EV cannot tell the whole story.
ICM without the fog
06
A check after the next session
Royalgrind revisits the same pattern on new hands and shows whether the habit actually changed.
Study, play, check again
A firm boundary
For the review after the game. Never for decisions during it.
Royalgrind analyzes completed hand histories. It does not connect to poker tables, place bets, or provide real-time decision assistance.
