====== Knight Line ======

Four-in-a-row by splitting stacks of knights on an unbounded square grid.

Inventor: Stephen Tavener

===== Rules =====

See [[http://www.nestorgames.com/rulebooks/KNIGHTLINE_EN.pdf|Knight Line rulebook (PDF)]].

==== Goal ====

Form four of your knights in a straight orthogonal or diagonal line. 

In a two-player game, if both players run out of moves without making 4-in-a-row, the second player wins.  In a three-player game, all players would win.

==== Setup ====

Default: each player has a stack of **20** knights in a fixed opening layout. Variants add a central blocker or wildcard and let players place the stacks.

==== Gameplay ====

On your turn split one of your stacks: move some of the knights a **knight’s leap** (2×1) onto an **empty cell**.

If you run out of moves, you will be autopassed. 
===== Variants =====

==== Blocker / Wildcard ====

A central neutral piece can either block all players or be counted by any player towards a 4-in-a-row. In these variants initial stacks are placed by the players.

==== Stack of 24 ====

Players get larger starting stacks.  This variant may be combined with one of the other variants.
