Tower 6

Tower 6 is played on a board showing 51 hexes. 24 of them are colored with 4 different colors and they constitute the four regions, where new playing pieces enter the board.

Equipment:
1 normal 6-sided die
1 colored die (4 sides with 4 different colors, 2 sides wild)
10-12 stackable playing pieces (depending on the number of players)

Object of the game is to be the first player, who can build a tower of 6 own pieces.

The game starts with an empty board. During a turn, a player can enter a playing piece on the board, move a piece that's already there or attack an opposing piece (or tower).

Entering the board is very critical in this game. The location, where a playing piece can enter, is determined by the throw of both dice, but that space should be empty - or you either loose one of your own pieces/towers or your turn.

Therefore moving away from such entering spaces is important, but entering lots of new pieces or attacking opposing pieces is what leads to victory!

Movement is determined by a die roll, but the die is only needed to fix the direction, where a piece can move.
And attacks are even handled without using any die: they are simply decided by the height of the 2 involved towers.

Color Guard, Stronghold, Tower 6, and Where To? are 4 games designed by Ronald Corn in the 1980s that never found a publisher. They all had interesting mechanics and/or inventive victory conditions - but they had no theme! Since they were not pure abstract games (they used dice, cards, or tiles as random elements), this lack of a good theme could have been the main reason why they were never published.
