How can i restart the game without having to refresh the page?

`    game.setVariable(constant.successCount, 0)
    game.setVariable(constant.failedCount, 0)
    game.setVariable(constant.gameScore, 0)
    game.setVariable(constant.hardMode, false)
    game.setVariable(constant.gameStartNow, true)`

I can use these variables to reset the values but how do i go about starting the game from start without creating a new instance of the game?
