help=['','Eleven High is a historic dice game. In 1904, Eleven High was banned in Europe, together with several other games of hazard. You play against the computer. Start rolling the dice simply by clicking on them. For every roll, one point goes to the jackpot, and after the cast the numbers are added together. If your roll is a double six, you will immediately lose 12 points. Yet, if your roll is 11, you will win the jackpot. For every other result you will lose the difference between 11 and your roll. For example, if your roll is a five and a three (8 points), you will lose 11-8, hence 3, points. The game will end as soon as either you or the computer run out of points.'];
