Hi everyone,
I’m Jason — a 6-dan amateur and a Go teacher with 20+ years in the classroom — and over the past months I’ve been building a training site called Go Odyssey. I’d really value some blunt feedback from this community before I push it further.
It started from a frustration I kept seeing in my own students: people solve tsumego for a week, lose steam, and quietly drift away. They’re rarely short on ability — they’re short on a reason to keep showing up.
So I tried building something a bit different:
-
A 3-minute rank test (no signup) that places you on a provisional range
-
An explorable RPG-style world map — solve problems to lift the fog, unlock regions, beat area “bosses,” level up
-
A “Weakness Radar” that tracks your accuracy by topic (life & death, tesuji, direction…) and feeds you tailored daily problems instead of random ones
It’s still a serious training tool underneath — the game layer is just there to make consistent practice less of a chore. It’s free to use, and aimed mainly at the 10k–1k range.
Try the rank test here (no account needed):
I’m genuinely posting this for feedback, not as polished marketing. I’d love your honest take on:
- Does the rank test feel accurate to your actual strength?
- Is the English presentation clear, or are there rough spots?
- Does the “map + weakness radar” approach feel useful, or gimmicky?
Brutal honesty very welcome — that’s the most useful thing you can give me right now. Thanks!
