A board game for 2 players by Néstor Romeral Andrés (includes a variant for 3-4 players) INTRODUCTION HEPTALION is a special dominoes game played on a diamond-shaped board of 56 squares depicting 7 different symbols on them. Two players struggle to place their domino tiles on the board. The last player placing a tile wins. Example of tile placement: The dot-plus tile is placed on the location marked with a red rectangle. The first player that cannot place a tile loses the game. MATERIAL - A diamond shaped board with 56 symbols of 7 types. Example: It’s A’s turn. ‘A’ has no valid moves and loses. ‘B’ wins. Notice that ‘B’ still had room for some tiles (marked in red). VARIANT FOR 3-4 PLAYERS For a 3-player game, each player randomly takes 9 tiles (the remaining tile is discarded facing up and not used during the game). For a 4-player game, each player takes 7 tiles. - 28 different domino-like tiles with 2 symbols each (all combinations). Play as usual. If a player cannot place a tile, that player is eliminated from the game. The last player standing wins. NOTES AND PUZZLES - A carrying case. Notice that this special board configuration has the following properties: SETUP Place the board in the middle of the playing surface. Each player randomly takes 14 tiles and places them face-up before them, so both players can see them: a) Each symbol is shown exactly 8 times. b) Each domino is shown exactly 3 times. c) There are exactly 56 squares; the same number of squares that compose the 28 tiles. Variant: Draw and keep your tiles face-down or otherwise hidden (e.g. behind a screen) so your opponent can't see them. While there are other symbol distributions for this diamond-shaped board that exhibit the above properties, the designer has not found other board shapes yet. Determine the starting player (usually the one that lost the last game). Obviously it is impossible to place all tiles on the board, but… How many tiles can you legally place? HOW TO PLAY (2 PLAYERS) Can you find other non-trivial distributions? (not obtained by simply exchanging symbols or by rotation or symmetry). Players take turns placing one of their tiles on the board face-down so that both symbols of the tile match with the symbols of the two adjacent spaces on which the tile is placed. Can you find a different board shape with the same properties? Please contact me if you do! Rules and rulebook © 2012 Néstor Romeral Andrés. Revisions by Nathan Morse.
