The game was made by Keith Carter.
There are 3 types of moves:
Any opponents adjacent stones to the new piece (either through growth or slide) are
flipped to the moving player's color as in othello.
A drop of a stone on an empty adjacent (orthogonal or diagonal) empty cell;
An orthogonal or diagonal slide of a stone already on board (like a chess Queen) to an empty cell;
A drop of a stone on any empty cell.
The third option (simple drop) do not flip the color of adjacent stones.
Wins the player with most stones when the board is filled.
