Gazintas are numbers that divide exactly into another number (3 gazinta 21).
In the game you are given a number from 2 to 12 at the bottom of the screen.
Other numbers wander across the screen. Once you click on the number at the bottom of the screen it will follow the mouse pointer. You have to make the number attached to the mouse pointer touch a number that it 'gazinta'. The larger the number, the more points you score.
If you touch a number that is not a 'gazinta' then you lose points. You also lose points if your number touches a balloon. Balloons appear at random intervals and float up the screen.
