Wopple is a fun word game you can play alone or against others. 4.5 stars on almost 1500 reviews. iTunes URL: https://itunes.apple.com/app/id481584214 50 promo codes: http://www.tekiki.com/app-deals/promo-codes/535ae245186075464d000004
I presume that these are promo codes for the 69p version, not the free one as linked to. Also there are zero reviews for either version on the UK App Store.
Seems a very old game. Just 25 reviews on the uk store and only one this year. Rest from mostly 2011/2012?
