Cant be bother with heaven palace anymore, the boost costs bloody high and the prizes r ****, yeah prob u will get a better prize at higher lvl, but its almost impossible to get pass lvl 6 for most players. Since the tops 10 getting stronger much faster than other. So forget about it, if ur a poor players that cant afford to spend 5m credits on boost. Seriously, such a waste of time, credits, gems and all u get are disappointed prizes.
