Tower Chess is a chess variant that takes place on a 6x6 grid. The game does not include any knights, and 2 less pawns per side. Aside from the size, the main twist in the game is that rather than pieces being removed from the board, the pieces are tiles and they are simply stacked. When a piece is moved, only the top most piece of a stack is moved. Pieces that were once covered will be able to move again if the pieces atop them are moved first. You may "capture" your own pieces by landing atop them. As usual, the player to first capture the opponent's king, or in this case, place one of their pieces atop, will win.
