The aim of the game is to delete all numbers from the playing area. The numbers are deleted in pairs – either the same ones, or the ones amounting to 10 (ten).
The deleted numbers should be located either on one horizontal line, or on one vertical line, or on one line if you image the playing area as one long line. There should not be any other numbers between the numbers.
When on the playing area there are no more combinations to delete, or if you do not wish to delete certain pairs – you should press the «re-write» button and all remaining numbers will be written at the end after the last number.
As a result either the numbers will fill all playing area and the game will be over, or you will manage to delete all numbers and pass on to the next level.
