Race against the clock to connect groups of 3 or more matching numbered dots by dragging them around the board. As each group of dots is cleared from the board, new dots are added, and to make it more challenging new dots are added at regular intervals, and the numbers on some of the dots already on the board change to the next prime number. The longer you play, the faster the changes come!
The grid has a small number of random spots blocked off so there is a prime number of spaces for dots, and all the numbers on the dots are prime. The blocked spots also make it more challenging to connect the dots.
If you get stuck there are two options to clear off some dots, but there is a steep price: your score is cut by 10%! A long press on a dot will clear all matching dots from the board, and a long press on an empty space will clear away any groups of 3 or more connected dots.
