Your mission, should you choose to accept it, is to make the number on the right match the number on the left.
This you must do by selecting from the four glyphs, each one of which has a fixed, randomly assigned number which is unknown to you until you click it.
If your sequence of numbers equals the game number, you win the round. If your number exceeds the game's number, you lose that round.
Whether you win or lose, all new numbers will then be chosen, and the game will begin anew.
