We have a game of solitaire chess, with sixty-something different challenges.
As part of her school work, Rosebud has been making a new one every day for a while now. Yesterday's is one of the best so far.
The object of the game is to move the players using normal chess rules and capture others until you have one player left.
This one has two pawns, two bishops, and two knights. Each move must capture a player. One player remains at the end.
