Abstract Strategy

Numbers aren't worth anything in NMBR 9 unless they're off the ground floor and looking down from above.

The game includes twenty cards numbered 0-9 twice and eighty tiles numbered 0-9; each number tile is composed of squares in some arrangement. After shuffling the deck of cards, draw and reveal the first card. Each player takes a number tile matching the card and places it on the table. With each new card drawn after that, each player takes the appropriate number tile, then adds it to the tiles that they already have in play, with each player building their own arrangement of tiles.

The new tile must touch at least one other tile on the same level along one side of a square. A tile can also be placed on top of two or more other tiles as long as no part of the new tile overhangs the tiles below it; new tiles placed on this same level must touch at least one other tile, while also covering parts of at least two tiles and not overhanging.

Once all the cards have been drawn and the tiles placed, players take turns calculating their score. A tile on the bottom level — the 0th level, if you will — scores 0 points; a tile on the 1st level above this is worth as many points as the number on the tile; a tile on the 2nd level is worth twice the number on the tile; etc. Whoever scores the most points wins!

Fire, water, earth, wind — these four elements have driven mankind's mythology, philosophy and science for eons. Now, master the power of these primal forces in this abstract game of capture and area control.

In Element, players take turns drawing and placing four element stones to encircle opposing sages. Each element has unique properties that players can use to block an opponent's movement. Feed walls of flame, move raging rivers, raise impenetrable mountain ranges, and even bend wind to your command. Transform one element into another with the rule of replacement or sacrifice element stones to help your sage avoid capture.

Understanding the subtle, diverse, yet powerful nature of the four elements is key to surrounding your opponent and claiming victory!

The first player with a palace to amass 12 victory points (VP) in constructed buildings and captive Emperors in Ekö wins the game.

To set up, fill the board with all the pawns, placed at random. Before starting the game, each player can exchange their Emperor pawn with another of their pawns elsewhere on the board. On your turn, you must do both phases in this order: the action phase, then the reinforcements phase. During the action phase, you must perform one single action:

Move: Move to an empty space, regroup or attack; you can attack only a stack of enemy pieces that contains strictly fewer pieces than the attacking stack — except that a stack of four pieces can be attacked and destroyed by a stack of one piece.

Construct: You can construct only one building per space; subsequent construction on the same space replaces the existing building. Each terrain type allows specific types of construction. In order to construct a building on an empty space or on a space already containing one of your buildings, you must sacrifice pieces from a single stack adjacent to this construction space.

Once per turn, you can take an extra action by sacrificing three stackable pieces. A stack that contains the Emperor can attack an enemy stack even if it contains an equal number of pieces, and even if it contains another Emperor. Each enemy Emperor you have captive is worth 3 VP.

During the reinforcements phase, if you have pieces in your reserve, you must return at least one piece to play if you can.
You can place up to three pieces onto a single stack of your color on the board (never on an empty space), respecting the following rule: You cannot place reinforcements on a stack if it is adjacent to another player's building.

The game ends immediately when a player has amassed 12 VP by adding up the values of his buildings on the board and any Emperors they have captured — each village is worth 1VP, each tower 2VP, and each castle and captured Emperor 3VP — and they have at least one palace. Alternatively, if a player is the only one with pieces remaining on the board (making reinforcement impossible for the other players), they win.
