Pig Pog Poe

This is a board game I designed inspired by some of the 3d tictactoe variants I've seen floating around.

The pieces **stack** on each other vertically, but only some **rotations and combinations are physically possible** due to the shaped pegs on the top of the game pieces. Also stacking the pieces in different rotations can change the alignment of the sliding attachments and block some moves.

1. There is no set board. Players may build as far as they like in any direction until someone wins.
2. Players take turns placing one piece from their pile.
3. Pieces must be physically connected to at least one piece that is already in play.
4. Players may not attach a piece below pieces that are already in play.
5. A piece must be moved all the way to the bottom if it is able. However if a slider piece sticks out below it and blocks it, that is fine. Pieces can overhang in the air in this way. However pieces are not allowed to be placed below in this empty space (see rule 4).
