 How to play

Back to index
Initially the tiles corresponding to each player (by default 8) are distributed, and 7 numeric tiles are placed in center and the special ones over the board.

The player who begins has a * next to his name. If you are this one, you already can place tiles in the board. If not, you must leave the game begins clicking Start.

Once you have put all the tiles that you can in the board, you must click Turn to take tiles of the box, and let the following player. If you have placed all your tiles (and the box is not empty), 5 points extra by tile are added to you. If you play with 8 tiles by player, it will add 40 points extra to you. While the other players play, your tiles are disabled, and you cannot press them.

Also you can give back tiles to the box to change them by others. In order to use this option, you cannot place any tile in that turn. Select Exchange tiles, press the tiles that you want to give back, and then press Turn. Tiles can only be given back if there are tiles in the box.

To punctuate you must put one numeric tile on the board. The tile must solve one arithmetic operation with the two adjacent tiles. The three tiles must be touched each other in one vertex.

The operations allowed are: sum, subtraction, multiplication, division or power.

The points obtained when putting each tile are the value of that tile. If the cell has a D the obtained score is double. If it has a T, triple. In the cells with a X no tile can be placed. If the placed tile simultaneously solves several operations with diverse tiles, the result is the sum of all of them.

If you have placed all your tiles (and the box is not empty), 5 points extra by tile are added to you. If you play with 8 tiles by player, it will add 40 points extra to you.

 End game

Back to index
The game finishes when there are no left tiles in the box, and a player puts all his tiles. It is configurable to allow one more round in this case (not to add points but to remove his tiles). Also it that can occur that the game is blocked. In that case, it also finishes.

Once finished, each player subtracts his own tiles.

The one who has more points wins.

 Samples about how to place the tiles

Back to index
We are going to place tile 5 touching with the 3 and the 2. (3+2) (look the emphasized red vertex in the figure ).

First we click the tile 5 so that it remains sunk (selected).

We indicated with the mouse where to put the tile selected. If the operation is valid, the tile is placed. The value of the tile (5 in this case) raises to our marker. Also we could put the 6 (3x2) the 1 (3-2), the 9 (raise 3 to the power 2) or the 8 (2 to the 3) in that cell of the board.

Then we put tile 10 (5x2).

That cell has one D. It means that the score is Double. We obtained therefore 20 points more. We also could have placed the 8 (2x4).
