See link for video of the solution.

The point of the game is to get all numbers around the clock to 0. You play vs a bot.
You can either zeroize a number, or choose to do nothing.
The bot can increment a number if it's below the max size, or choose to do nothing.

The logic is pretty strange, and has to do with what value is adjacent to the value the arrow is pointing to.

I solved it by trial and error + a bit reversing of the Javascript code. The clue here is to find the logic.
The first step is to get all values to 1 around the clock, then zerioze a value to create the value 2.
The next step is to create another value of 2, and then get them positioned beside eachother and not adjacent.
After this has been done, it is pretty easy to fill up the rest of the board with 2's.

Once all values has reached the maximum value, the bot won't increment them, and we can just zeroize every value to get the flag!
