Camelot has withdrawn a lottery scratchcard because some players couldn't understand the basic maths the game was based on.
The Cool Cash game was launched on Monday but was taken out of shops on Friday because players were unsure whether they had won.
To win a prize, users had to scratch off a window to reveal a lower temperature than the one displayed on each card, which was usually below freezing.
But dozens of players who could not understand how, for example, -4 was higher than -5, filed complaints with Camelot.
Tina Farrell, 23, from Manchester, called Camelot after failing to win with several cards.
She told the Manchester Evening News: "On one of my cards it said I had to find temperatures lower than -8.
"The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.
"I phoned Camelot and they fobbed me off with some story that -6 is higher - not lower - than -8 but I'm not having it.
"I think Camelot are giving people the wrong impression - the card doesn't say to look for a colder or warmer temperature, it says to look for a higher or lower number.
"Six is a lower number than 8. Imagine how many people have been misled."
A Camelot spokeswoman said the game had now been withdrawn.
"The instructions for playing the Cool Cash scratchcard are clear - and are printed on each individual card and in the game procedures available at each retailer. However, because of the potential for player confusion we have decided to withdraw the game."
