Rules

The player places tiles (digits (0-9), operators (+, -, x, ÷), and equals (=)) on the board in a linear sequence so that they represent mathematical equality. This is called ‘single move’ or ‘move’.

The tiles played in a single move must be placed in a single horizontal or vertical line.

There must not be empty spaces between the tiles played in a single move.

Equality built in a single move must contain at least one tile played from a previous move, except for the first move. In the first move, one tile must be placed at the center of the board which is marked with a star.

All equalities built in a single move must be mathematically correct.

Equality built in a single move must contain one ‘=’ tile.

Equality built in a single move must contain at least one operator tile.

A number can consist of one or more digit tiles.

If a number consists of more than one tile, the first tile in the number must not be ‘0’.

A sack is a group of 100 tiles randomly chosen for a player to use in one game.

A drawer is a group of 10 tiles randomly chosen from the sack that a player can use during his or her move.

Each player must use at least one tile from the drawer to successfully complete a move.

Every tile a player uses in a move gets replaced with a random tile from the sack after the move is completed.

When a player can not or does not want to create a valid equality with the tiles in his or her drawer the player can either a) skip a move – in which case there are no changes to the game but the opponent gets the move, or b) swap tiles – in which case the player chooses which tiles from his or her drawer to return to the sack and replace with random tiles from the sack, and the opponent gets the move.

Points value of each tile: For tiles 0, 1, 2, 3 a player gets 1 point; For tiles 4, 6, +, – a player gets 2 points; for tiles 8, 9, x, ÷ a player gets 3 points; For tiles 5, 7, = a player gets 4 points.

Points earned by a player in a single move (pts) are calculated through the following equation:

pts = value of all the tiles placed in that move + value of all the tiles placed in previous moves that are part of the equation created in a current move.

A tile placed over the field on the board marked with ‘2X’ doubles its value.

A tile placed over the field on the board marked with ‘3X’ triples its value.

If a player places a tile over ‘2E’ field of the board, all the tiles placed in that move double their value, and any tile that was played in one of the previous moves and is also part of the equation created during the current move also doubles in value.

If a player places a tile over ‘3E’ field of the board, all the tiles placed in that move triple their value, and any tile that was played in one of the previous moves and is also part of the equation created during the current move also triples in value.

Fields ‘2X’, ‘2E’, ‘3X’, ‘3E’ are used as multipliers only in the move when a tile is placed over them.

Fields ‘2X’, ‘2E’, ‘3X’, ‘3E’ can be combined, and the points value is calculated in the order these fields are defined. (For example: if in a single move one tile is placed over 2E field and one tile over 3X field, first the tile placed over 3X field triples its value and then all the tiles double their value, which makes the tile placed over the 3X field multiply its value 6 times).

Points earned in a single move are added to the points from all the previous moves to create a player’s current score in the game.

The winner of the game is the player with the most points when there are no more moves or tiles left to play for both players, or a player whose opponent resigned, or a player whose opponent failed to complete a move within 48 hours.
