DIAMOND VS DOWNFALL

DIAMOND
Diamond is a two-player abstract strategy board game invented by Larry Back. The invention was inspired by the game Kensington, which uses a similar board pattern and game objective. Rules for Diamond were conceived in 1985 and finalized in 1994. Diamond introduces a new board geometry and neutral pieces, with the aim of enhancing the game dynamic and lowering the potential for draws. Diamond was featured in the February 2013 issue of Games magazine. The Diamond gameboard consists of interlocking squares and triangles. White and Black each control 12 game pieces of their own color. Neutral pieces (red-colored in the diagrams) enter the game via captures. The pieces are played on the line intersections (called points, as in Go). White and black (but not red) pieces can move along straight lines to adjacent unoccupied points. A player wins by being the first to occupy all four corners (points) of a board square with their pieces. Capturing moves are possible in the Movement phase. If the points of a triangle contain exactly one white and one black piece, either player can capture the opponent piece by occupying the remaining open point ("cornering" the enemy piece on the triangle). The captured piece can be cornered on one triangle (see Example 1), or simultaneously cornered on two different triangles (Example 4). The captured piece is immediately removed from the game and replaced on its point by a neutral piece. If a move simultaneously corners two opponent pieces on two different triangles, then neither enemy piece is captured (Examples 2 and 3). A piece can move safely to a triangle point even if the other two points of the triangle are occupied by enemy pieces (Example 5).

DOWNFALL
Downfall is a two-player game for players aged 7 and older, first marketed by the Milton Bradley Company in 1970. The game consists of a vertical board with five slotted dials on each side. Each player starts with ten numbered tokens or discs at the top of the board. The object of the game is to move the discs to the bottom of the board by turning the dials. Players alternate turns moving the dials and cannot move a dial that their opponent has just moved. The winner is the first player to move all of their discs into the tray at the bottom. An advanced version of the rules dictates that the discs arrive in the tray in numerical order. Since neither player can see the other's board, it is common to inadvertently advance - or hinder - the opponent's gameplay. The game rewards forward thinking and planning; players may try to "trap" their opponent into turning a dial that will advance their own disc, while trying to ensure that their own discs are not caught and dropped out of order. The game is currently available in the UK under the name New Downfall, manufactured and marketed by Hasbro. The new version follows the same rules but has a more futuristic design in red and yellow. The game's box art is parodied on the cover of Expert Knob Twiddlers, an album by Mike & Rich (Mike Paradinas & Richard D. James).
