No worries there, ClixGrid's all based on one's luck -- there'll be days that one user may score a prize ( whether it be extra chances, or one of many of the cash prizes ) and some may be even luckier to score more than once... and there'll be some that won't score anything for the day
So don't feel disappointed if you didn't win anything for today; there's another day -- another server cycle -- and another chance to be lucky -- just keep on clickin'
( Edit: adding my screencap a bit late, still played the ClixGrid earlier, and won )
