You need four sets of colored stones, fifteen stones in each set. Keep these stones in a bag or bowl nearby. The game board is a 6×6 grid. Arrange twelve stones on the board as shown below.

Turn Order
Two players take turns. One player is called Pebble. The other player is called Rebel. Pebble takes the first turn.

The Pebble
On her turn, she may move a stone on the board in straight horizontal or vertical lines as many times as she wishes to until the stone reaches its final destination. She may not pass through any occupied spaces along the way. Diagonal movement is also not allowed.

In the example above, Pebble moves the black stone down, then left. She is trying to build a line of black stones along the bottom of the board.

The Rebel
On his turn, he randomly draws a number of stones equal to the number of moves Pebble took. Then he places those stones on any unoccupied square.

In the example above, Rebel draws two stones because Pebble moved a stone twice. He then places those stones on the board. He chooses these spaces in particular to block Pebble’s efforts.

If Pebble gets four stones of the same color in a row, horizontally or vertically, she wins. (Diagonal four-in-a-row does not count.)
If Rebel fills up the whole board, he wins.

The above example shows how Pebble or Rebel could win.

In the example on the left, Pebble succeeded in creating a four-in-a-row, thus winning the game.

In the example on the right, Rebel successfully filled up the board before Pebble could get four-in-a-row, thus winning the game.

Pebble’s play style suits fans of puzzle games with randomized elements, like Tetris or Bejeweled, but against a much more clever computer. Pebble has to be sneaky, arranging a four-in-a-row using as few moves as possible.

Playing Rebel is great for button-mashers, “take that” players, and those who just choose tactics on a whim. Still, Rebel must be wary of placing stones where they might easily be used by Pebble.

Before the board fills up, there will probably be an obvious “checkmate” situation, in which it is clear Pebble cannot create four-in-a-row.
