Choose a practice puzzle, use pencil notes and take your time. Private races and archive replays offer more ways to play.
The daily race gives your solve a result: an opponent, a rating change and a record you can follow. Practice is a separate space to work through puzzles with pencil notes, without putting your daily Elo on the line.
