Learn openings. Play with confidence. Know how the pieces move, but feel lost in the opening? Remember a sequence in practice, then forget it in a game? ShogiStep: Learn Openings helps you study Japanese chess openings by moving pieces on a board with your cat coach. Developed by a Learning Engineering PhD and amateur shogi 2-dan, with commentary supervised by a shogi 5-dan. Understand the ideas, recall the moves, and build your opening knowledge through hands-on practice. UNDERSTAND WHY EACH MOVE MATTERS Openings are sequences refined through games and study. Memorizing moves alone can leave you unsure when an opponent chooses a different line. Learn what a move prepares, what threat it prevents, and how it helps your pieces work together. Your cat coach explains the ideas alongside the board, making positions easier to follow than notation alone. LEARN MODE: ONE MOVE AT A TIME Highlights show which piece to move and where to place it. Tap or drag to play while reading the commentary. Tap a square reference in the explanation to light up that square on the board. Enlarge the commentary for easier reading. TEST MODE: RECALL, PLAY, REVIEW Try the opening without move guides. A mistake does not end your attempt: after two mistakes, a hint helps you continue. Review the commentary after a correct move. At the end, check your first-try accuracy and mistakes, then practice again.
