A side panel that lives in your browser. Train tactics between meetings, between tabs, between thoughts — without ever leaving the page you're on.
Most chess trainers want your full attention. This one doesn't. It opens in Chrome's side panel and stays put — solve a puzzle, close it, get on with your day.
The endgame (or end game or ending) is the stage of the game when few pieces are left on the board. The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs of pieces.
The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important; endgames often revolve around attempting to promote a pawn by advancing it to the eighth rank.
The king, which has to be protected in the middlegame owing to the threat of checkmate, becomes a strong piece in the endgame. It is often brought to the centre of the board where it can protect its own pawns…
Every puzzle is a real position from a real game on Lichess — rated by thousands of players who tried it before you. No synthetic positions, no padding.
A modern board with the small details that make solving puzzles feel right — legal-move dots, capture rings, last-move highlights, undo, full move history.
Pick a piece, see legal moves as dots, ring-highlights around capturable enemies. Or just drag the piece where you want it.
The opponent's move is highlighted on the board so you start every position knowing exactly what changed.
Played a wrong move? A clean overlay lets you take it back, retry the puzzle from the start, or skip it entirely.
Right-click and drag to draw arrows. Right-click a square to highlight it. Think out loud, plan a combination, mark the threats — all without leaving the puzzle. Available on every plan.
The classic two-column table. Every move, every variation you tried. Scroll back, see where the puzzle turned.
Stuck? The hint nudges you twice. First it tells you which piece to move. Only if you ask again does it draw the arrow. The puzzle still teaches you something.
The piece you need glows. The square sits highlighted. The destination is still up to you.
Still stuck? An arrow points to the destination. The mate is on the board — you just have to play it.
Tap a theme or piece set — the board on the left updates the way it will in the extension. The rest of the page stays as it was.
