Rococo is a development of Ultima, and like in Ultima, most of the pieces move like Queens, but capture in various ways. Rococo started as an experiment in making a version of Ultima more favorable to attack and clearer in its play. The result, however, is rather far from Ultima, but still seems to be an interesting game in its own right, where attack is stronger than defense, and that possesses reasonable clarity.
 
The object of Rococo is to capture the opposing side's King. There is no check or checkmate. A stalemate or three-times repetition a loss for the player unable to move or repeating the move.
 
The pieces:

• The Advancer captures by approach, and the Withdrawer by withdrawal.
• The Long Leaper captures hostile pieces by leaping over them, although it may not leap over friendly pieces. Multiple hostile pieces in a line with spaced between them may be captured in a single move.
• The Swapper can change places with any piece of either side an unobstructed Queen's move away, or move like a Queen without capturing. It may also capture an adjacent piece by mutual capture (both the Swapper and the target are removed from the game).
• The Immobilizer can not capture, but any hostile pieces next to it are unable to move.
• Cannon Pawns move without capturing like Kings, and may leap over adjacent pieces of either side, landing just beyond, and capturing any piece that might occupy the square landed in (capture by bombardment). On any move that lands them on the back two ranks (counting the outer ring), they may promote to any previously captured piece.
• The Chameleon captures other pieces the way they capture, leaping over Long Leapers, approaching Advancers, etc. It immobilizes opposing Immobilizers, and may Swap with opposing Swappers.
