Every move, honestly graded.
You play the dan's moves in real analyzed games against weaker opponents. Each guess is scored by winrate against KataGo analysis — no vague "good move" pats on the head. Your Dan Level % is the share of your moves that held dan strength.
See the punishment, not just the mistake.
When your opponent slips, Compare shows you both futures side by side: the game as it went, and the game as it should have gone — unfolded move by move at 5-, 7-, and 9-dan strength. Then drill the refutation yourself.
Earn your way up.
Start free with the full 2-dan tier — twelve complete games. Prove yourself to unlock the 3-dan tier permanently: it can only be earned, never bought. Everything above is one purchase, yours forever. No subscription. No ads. No account.
At the moments where a 10-kyu, a 7-kyu, and a 1-kyu would each play a
different move, Road to Shodan shows you how the ranks split — and which
rank played like you.
