Tear down the wall is a 2-player shareware game for MS-DOS by Chet Langin (with options of human vs. human, human vs. computer, or computer vs. computer).
The playing area is an 80 by 12 grid, the 'wall'. The wall is made of bricks of four different sizes; each brick is one grid unit tall and one to four grid units wide. The entire grid is filled randomly at the beginning of the game. Players take turns, and each turn a player picks a brick from the wall. That brick disappears, and bricks which are supported by it fall down and disappear too. For each move, the player gets a score equal to the area of the wall which disappears. The winner is the one with the highest score when there are no more bricks left. (It should be clear that the total of both players scores at the end of the game is the total area of the wall; this being an even number, draws are possible. But they seldom happen.)
There are two 'special' types of brick: weak bricks and heavy bricks. Normal bricks will only fall if all the space immediately below it is empty - if just one corner of the brick is supported, it does not fall. Weak bricks will disappear if any of the space beneath it is empty. When a normal brick falls, it just disappears, but when a heavy brick falls, it destroys the brick(s) it lands on before disappearing. (Bricks cannot be both heavy and weak at the same time.)
It is a relatively simple game. Play a game or two and you know all you need to know to play. There are some subtleties, though. A weak brick or a heavy brick on the bottom of the wall is no different from a normal brick. A heavy brick on the second row from the bottom is no different from a normal brick. And a weak brick which is fully supported by only one brick below it is no different from a normal brick. Keeping these things in mind can help clean up complications in planning the next move. Making a move which destroys the most brick-area is not necessarily the best move; doing so may afford your opponent an even bigger-scoring move after that.
I enjoy this game because it's a different game each time I play. There's no luck, it's purely a skill game. And maybe some of the fun is just the fun of destroying stuff.
