Defined spots
The ranges, stack, board, actions, and response model are stated before grading.
The product
A study routine built from the way you actually play.
Royalgrind reads completed hand histories, finds decisions that repeat, and carries the pattern from explanation into Solved Mode practice before your next session.
The signature mode
Practice with a result that was known before you played.
Solved Mode uses precomputed Nash and exact-EV spots. Revealed study runs teach the action values; ranked gauntlets keep the answer key off-device and grade the set on the server.

Review the cost of the decisions, not only a right-or-wrong label.

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.
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.

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.
