Select the column you?d like to drop the number in using the mouse.
Numbers disappear when they equal the amount of numbers in their row or column.
When numbers disappear, they crack the grey circles that are touching them. If the grey circle is already cracked, it turns into a random number.
Each level-up is accompanied by a new row of grey circles.
On a rare occasion, you may get a special bomb block. This acts as a normal number for chains, except that it counts down by one at the end of each turn. In the rare occasion of a bomb reaching 0, it will explode and clear some of the board!
