Number Guess FRVR will try to confuse you, but at the same time train your instincts and, in particular, observation and reaction. A number will appear in a large window at the top, and a number will appear below it in a second one with up and down arrows on the right side. These arrows will become your main control element. The number at the bottom will change, you should quickly compare it with the top and press the up arrow if it is larger and down if it is smaller. Make no mistake, otherwise the game will end. There is very little time for reflection, the scale at the very top may disappear and you will not have time to answer in Number Guess FRVR.
