Why can't the text games be more like http://www.thewinningtxt.co.uk its a very simple concept but works very well. Its basically a count down system - each text received for the particular prizecode reduces the amount of texts needed for the prize to be won by one making the prize closer to being won, but you won't know how close you are until you text in. If the numbers high leave it a bit and them have another go but if the numbers low text back start away. Its only 50p unlike most other competition which generally are around £1.50 plus you hear back from the winning text telling you how close you are to winning - its the only competition that I know of that tells you how close you are to winning instantly. There can't be any trickery here and the winners can't be pre-selected as its a count down system so if they were investigated one look at the database would confirm this instantly.
