On iPhone and iPad, add the trainer to your Home Screen first: tap Share, then Add to Home Screen, and add decks from there. Safari deletes a website's data after 7 days without a visit; the Home Screen app keeps it.
Install the trainer as an app to study offline from your home screen.
Backgammon trainer, no Anki needed
Answer positions, see the analysis, and get each one back just before you would forget it. Works offline on your phone or computer, with no account.
Have a match or some positions? Make a deck from them in the web app.
It reads XG and HedgeHog files, and analyzes .mat files and position IDs with HedgeHog. Moving from another device? .
Drills
Blunder Streak
How many positions in a row can you get right? One miss ends the run. A checker play within 0.020 of the best keeps you going.
Storm
Three minutes to get as many right as you can. Each miss costs 10 seconds.

How it works
- Pick the play. Each position asks for the best move or cube action, like the AnkiGammon Anki cards.
- See the analysis. The answer shows every candidate with its equity, the winning chances and any notes. Tap a move to see it played on the board.
- The trainer grades you. The best play counts as Good, a checker play within 0.020 as Hard, anything else as Again. Change the grade before moving on if you disagree.
- It schedules the reviews. The trainer uses FSRS, the same scheduler modern Anki uses, so positions you know come back less and less often.
- Drills are for speed: Blunder Streak ends at your first miss, and Storm gives you three minutes. They don't change the review schedule.
Your decks can come from the community, from the web app (your own matches and positions), or from the desktop app with File → Export to Trainer. Already use Anki? Keep using it: the same decks import into Anki too.
