I`d love to enjoy the game, but please explain it a little better. What or where is the top face?
Okay so it's like you're looking down at a 6 sided die on a chessboard. The white square is the die. The number you see on it is the number on the top face of the die. when you move, the die rolls 90 degrees in that direction onto the next square, moving one of the sides on top. if the number on the die matches the number on the tile it's sat on, it clears that square.
This game mostly tests your ability to visualise the die in 3D despite only ever seeing the top face.
