This is something I came up with last night. No play testing and I don’t even have the pieces needed to play. This is very rough.
It is a two player game that uses 2 sets of tree house pieces. That’s 30 pyramids in 5 different colors and 3 different sizes.
Setup: Take all of the large and medium pyramids and randomly place them into a 4×5 grid. Then both players take turns placing the remaining small pyramids on top of the large and medium ones of different colors.
Play: Players take turns moving a single pyramid one space on the grid. A player may immediately move the same pyramid once more if it landed on a larger pyramid of the same color. At no time can there ever be more than three pyramids stacked. A player may only move a pyramid a maximum of two spaces during his turn.
Goal: To get sets of three pyramids that are stacked from largest on top to smallest on bottom. This scores 1 point if it the stack is made up of 3 colors, 2 points if made up of 2 colors, and 3 points if made up of 1 color. Once a player has formed a triple stack he must immediately remove it from the table and place it in front of him. The empty space on the board may be moved into by other pyramids.
Game ends when one player has 5 points.
