About TsumeDojo
TsumeDojo is a free, bilingual collection of solver-verified “tsume” (endgame) drills for five board games.
What we do
We offer endgame drills for tsume shogi, tsume othello, renju (gomoku VCF), riichi mahjong tile-efficiency, and tsumego (go capturing). Every answer is checked by a computer, so you never have to wonder whether a puzzle is sound. It is free, needs no sign-up, and saves your progress on your own device.
How the problems are made
Problems are either generated automatically and then proven by an exhaustive solver, or taken from openly published datasets — for shogi, the YaneuraOu public tsume collection, used with the author’s permission. We never copy other people’s composed puzzles or problems lifted from other sites, and we do not use professional game records or commercial app data.
Who it’s for
From newcomers learning what a “four” or “tenpai” is, to players drilling toward a rank. Each game has a short how-to-play and strategy primer, and shogi adds a rank test, printable worksheets, columns, and castle/opening guides.
