You play as Red against Black.
In the game Be-Jay each player has 8 Bumpers (on the first rank) and 8 Jumpers (on the second rank).

Only forward or diagonally forward moves are allowed. In the following, all these moves are called 'forward moves'.

A Jumper may:
- move forward one step towards an empty position or
- move forward two steps towards an empty position; if the intermediate position is an enemy piece, it will be captured.

A Bumper may:
- move forward one step towards an empty position or
- move forward two steps towards an empty position; the intermediate position must be empty.
If in one of the two cases above the Bumper 'bumps' into another piece (i.e., the moving piece ends up with another piece in front of it), then the player can execute another partial move with that piece. This additional partial move is allowed to be a capturing move: a capturing move goes 1 or 2 steps and ends up on an enemy position. No more partial moves are allowed after a capturing partial move.

To pass a partial move, click the lightning sign at the tool bar.

When a player is stalemated, the player with the most pieces wins.
Repetition is a draw.
