<-- magic sum position: x y --> <-- 'New' button position: x y --> <-- 'Level' button position: x y --> <-- score position: x y --> <-- bubble diameter --> <-- distance to central bubble --> <-- central bubble center: x y -->  

The goal is to add up the 3 numbers on each line and all the sums of the lines must be equal. The magic sum is the hint.

[Tips]: Divide the magic sum by 3 and you will get the value that must be in the center in order to complete the puzzle. Click on a bubble on the outside to swap the number positions. A solid bubble indicates a valid number placement on the line. To start a new game, click on the 'Restart' button.
