Sorry, not yet. But here they come.

Two player X and Y, moving in turn, X to start.
Passing is not allowed.

A move consists of two parts:
(i)rolling dice
(ii) pushing one own piece one square "forward"

Each player has 6 stones in the beginning, with numbers
1, 2, ..., 6. The quadratic board has size 5x5.
Player X starts with all his stones in the 6 squares of
the upper left, player Y in the lower right.
(Each player is free to select the arrangement of his stones
on the six starting squares.)

Example starting position:
x1 x6 x3 -- --
x5 x2 -- -- --
x4 -- -- -- y2
-- -- -- y3 y1
-- -- y4 y6 y5

Feasible directions for X are one step to the south, to the
east, and diagonally to the south-east.
Feasible directions for Y are one step to the north, to the
west, and diagonally to the north-west.
A move may be to a free square or it may capture an opponent
or it may capture an own piece. (Often it really helps to
capture own stones!)

The meaning of dice rolls:
A player has to move with the stone that has the number
he just rolled. When this stone is no longer on the board,
he has to move with the next-larger number he still has or with
the next-smaller number he still has.
Example: X still has stones 1,2,5. Now he rolls a "4".
So he is allowed to push either the 2 or the 5. (It does not
matter that the 5 is nearer to the 4 than the 2!)

End of game is possible in two ways:
(i) When a player reaches the corner square of the opponent he has won.
(ii) A player with zero stones remaining has lost.

Please complain, when things are still unclear.
