Puzzle Storm: as many puzzles as you can in three minutes.

Puzzle Storm starts a three-minute clock and serves puzzles one after another. A wrong move costs 10 seconds, and a run of correct solves wins time back. When the clock runs out, you can go back through every puzzle in the run.

Choose a puzzle difficulty, and see your puzzle rating over time.

Pick a difficulty from Easiest to Hardest on the puzzle page, and it is remembered between visits. Your profile now charts your puzzle rating, one point per day, and lists each day you did puzzles in Activity. After a puzzle you can also report a problem with it.

Puzzle Streak, and puzzles by theme.

Puzzle Streak serves puzzles that get harder as you go, with no clock and one skip, and one wrong move ends the run. The new themes page lets you train one theme at a time, such as a single mate pattern. Each puzzle now plays in the moves of the game it came from before you start.

3D pieces, and banqi tiles that turn over.

Xiangqi, jieqi, banqi and Flip Jungle pieces can now stand in 3D: pick 3D under Pieces in the board settings. A banqi tile turns over when it is revealed, and stepping through a finished game glides each move into place.
