There are the virtual number-warehouse as well as the virtual number-box in the game.

Empty boxes can be packed with numbers. Both of the numerical order type and the numerical summing type are available. There are easy, medium and hard mode per each type.

The next number is shown one at a time from the virtual number warehouse.

The player can put the number only from left to right of each box. Every time all cells of a box are filled in the specific way, one score is earned.

The specific way for the first 9 games is the numerically-ascending or descending way. For example, if a 3-cells box was packed in the order of 3, 4, 9 or 7, 6, 1, one score would be earned.

Another way for the next 9 games is the order-irrelevant numerically-summing way. For example, if a 3-cells box was packed with 9, 2, 7 or 7, 9, 2, one score would be earned because 2 + 7 = 9.

Whenever one score is earned, the box turns to green. Each game mode has its own winning goal. 18 game modes in total are ready for you.
