Sky Scrapers

Sky Scrapers is an abstract and strategy board game for 2 players.

Each turn, a player moves one of his own stacks a number of spaces equal to the height of the stack, stacking it onto of another stack. A stack is owned by the player whose piece is on top.

The game ends when a player cannot make a legal move. Then, each player counts how many skyscrapers (stacks of four or more pieces) he has. The player with the most skyscrapers wins the game.
