A Reversi styled game with Chessboard Knights.

For each turn a player drops a new Knight on the board at an empty square, provided that there is an existing friendly side Knight within a connecting Knight's move (2+1) in place.
Any and all Enemy side Knights within striking distance of the newly dropped piece are SWITCHED to the other player's side.

If a player cannot drop a new piece, given the game's current layout, that TURN is PASSED and play continues. Once the board is filled, most Knights per side wins.
Identical NO Forced PASS variants are also included.

*An optional zrf version WITHOUT score indicators is included.
