Help
How the views and the settings work, what the analysis is telling you, and what to do when something looks wrong.
Getting started
What HedgeHog is, how to start a game, and how to move the checkers.
Playing
The Tutor, hints, auto-roll, auto-complete, Zen mode and the board itself.
Analysing a match
Running an analysis on this device or on our servers, the depth ladder, importing from other programs, and where matches are saved.
Reading the analysis
Equity, the error symbols, and the three numbers a finished analysis gives you.
Notes on a match
Writing notes on a match, a game, a move, a cube decision or one candidate play, drawing arrows and highlights on the board, who sees them, sharing a match with a coach, publishing an annotated match to the archive, the email about a coach's notes, notes in downloaded and imported files, and finding notes again.
The cube
Doubling, taking and passing, and what the cube panel is telling you about each.
Study
Building a tree of positions, branching on a roll, and keeping what you explored.
Transcribe and broadcast
Recording a live match as it is played, streaming it to a watch link, and what happens afterwards.
Settings
What each setting does, and which of them change what the engine says.
Keyboard and controls
Every key each surface listens for, and the two mouse gestures that are not obvious.
Accounts and plans
What is free, what an account adds, and what the two paid plans are for.
Glossary
The words backgammon uses about the board, about a plan and about the cube.
Installing, offline and troubleshooting
Installing HedgeHog as an app, what works with no connection, and what to do when something looks wrong.
What's new
What each update to HedgeHog brought, newest first.
