About the game
A grid of nine by nine digits slides slowly down the screen as new rows appear at the top. Moles crawl among the digits. A mole does not look like anything. Instead, each one has a number from 0 to 9, and it adds that number to the digit of the square it sits on, wrapping around at ten, so a 7 with a mole of 5 on it reads as a 2. A mole that steps to the next square makes the digit it left return to normal and changes the one it has stepped onto.
At the bottom of the screen is the target number, such as TARGET = 3. Your job is to find the mole that carries it, by noticing which digits do not match what was there a moment before, and tap its square. Do that and every mole on the screen is cleared, each scoring its own number, and a new target is chosen. A tap on a square with a mole that carries some other number removes that mole but costs points equal to its number, and any tap on the grid, hit or miss, pushes the grid down a little.
If a mole that carries the target number reaches the bottom row, the game is over. This is one for slow and careful play: remember what the digits looked like and watch for the ones that change.
Mole N is one of the mini-games that Kenta Cho, who works as ABA Games, makes with his crisp-game-lib library. There are no image or sound files: the graphics are drawn by the code, and the sound effects and music are generated while you play.

A few things worth knowing
Remember the grid. The only way to see a mole is to notice a digit that has changed, so look at the numbers before the moles reach them.
Compare the arithmetic. A mole that changes a 4 into a 9 is a 5. Do the sum before you tap.
Do not tap at random. Every tap, right or wrong, shoves the digits towards the bottom a little.
