Hong Kong

Hong Kong is a 1999 Reiner Knizia building game, published at Platnik.

The game includes the 5x5 board, 40 standard building-blocks in two colours, ten fast building-blocks (in two colours, with white imprint), and ten roofs (in two colours).

The rules (also available at BGG):

Objective. The objective of the game is to control more buildings than your opponent, when all plots are occupied, or when all standard building-blocks and roofs have been used. A building is controlled by the player whose piece is topmost on it. 

On his turn, a player chooses one of the following options: 

• to place one standard building-block
• to place one roof
• to place one fast building-block, followed by a standard building-block
• to place one fast building-block, followed by a roof

Corresponding to his five fast building-blocks, each player has the opportunity five times, during the game, to perform a 'double' move. 

When placing pieces, the following rules apply: 

• On the starting player's first turn, a piece may not be placed on the centre plot.
• If a player places two pieces in a turn, he can place them on the same or two different plots.
• Any type of piece can be placed upon any empty plot, even a roof.
• No piece may be placed on top of a roof.
• The maximum height of a building is five pieces.
• Players may always place on top of their own building-blocks.
• In order to place on top of an opponent's building-block, the player must control a building on an adjacent plot (i.e., with an edge in common) such that the newly placed piece does not create a building that is higher than the adjacent one. For this purpose, note that building-blocks are considered higher than roofs.
  

The game ends in one of two ways:

1. when, at the end of a turn, all 25 plots are occupied; or
2. when, at the end of a turn, all standard building-blocks (not necessarily all fast building-blocks) and all roofs are used up.

The player who controls more buildings wins. If both players control the same number of buildings, the player who controls the building on the centre plot wins.
