worst ive had was on ladbrokes games, 1-13 hi lo.... was sitting on a 1 , so i thought it was no-lose. I placed £500 for higher, would win like £20 (£520 return including stake). What happened next? It spinned in another "1" and i lost 500 bucks. I didnt realise it could spin the same number again . I was gutted.
Needless to say i didnt play that stupid game again
