- The first player combines numbers and operators to form possible equations. He or she takes as many equivalence tiles as needed to complete an equation. The player places the tiles forming the equation onto the board to read across or down. One of the tiles must be on the center square. All equivalence signs must be used. Diagonal equations are not permitted.
- A player completes a turn by announcing the score for the turn. If there is no challenge, the player then draws as many number and operator tiles as (s)he played, thus always keeping exactly seven number and two operator tiles in his or her rack.
-
Play passes to the left. The second player, and then each in turn, adds
numbers, operators and equivalence tiles to those tiles on the board to
form new equations. All tiles played in a turn must be placed in one row
across or down the board. Newly placed tiles may touch tiles in adjacent
rows or columns if:

The result is a number i.e. you may lay a number tile next to another
number tile.

Laying the 2 under the 5 is OK because it forms a number, 52. -
The result is the possible beginning or end of an equation.

- The player cannot place an operator next to another operator or an equal sign.
-
The result is a number i.e. you may lay a number tile next to another
number tile.
-
Therefore, new equations may be formed by:
- Adding numbers, operators, and equal signs to numbers or equations already on the board.
- Placing a new equation at right angles to an equation already on the board. Either the new equation must use a number, operator or equal sign already on the board, or if adjacent to any other tiles, start the basis for a new equation. All resulting equations must be true.
- No tile may be shifted after it is played.
- A player may use a turn to exchange all, some or none of the numbers or operators in his or her rack. To do this, place your discarded tiles face down back into the respective number and operator containers. Then reshuffle the tiles.
