Nine holes

 Nine holes is a two-player abstract strategy game from different parts of the world and is centuries old. It was very popular in England. It is related to tic-tac-toe, but even more related to three men's morris, achi, tant fant, shisima, picaria, and dara, because pieces are moved on the board to create the 3 in a row. It is an alignment game. 

The board is empty in the beginning. Players decide what colors to play, and who will start first. The game is then played through two stages:

Drop phase

Each player drops one piece per turn on any vacant space on the board. Players alternate their turns. Pieces cannot move until all three pieces have been dropped.

Move phase

After each player's three pieces have been dropped on the board, each player can move a piece to any vacant space on the board. Only one piece can be moved per turn.

Players can create the 3 in a row at either the drop phase or move phase, and win the game.

lordosis

 Lordosis is historically defined as an abnormal inward curvature of the lumbar spine.
