After a while playing, people know that Lucky Card is "rigged"! You would think you have one out of nine chance to get the highest energy, but in fact you have even chance to get different low energy except the highest one. You would also think if you stick on clicking one box out of nine, you will finally get the highest energy, again, you won't. Finally you realize that you are fooled by PF. By the way, this is the only bad reputation I have about PF: fooling player. The suggest I give PF is: if you want player win the highest energy, don't rig the game, this also save you effort to implement the game. If otherwise, design a different form such as slot machine. Don't fool players. Don't make us think you are a cheater.
