Tasty Bingo Christmas deal

As I said I was going to stay in this weekend and see what Bingo deals I could find for the festive season I seem to have already found one that sounds pretty good! Tasty Bingo are offering a Joy Xmas Special where players can win up to £1500 risk free. When I saw risk free I was a bit confused but depending on how many sites players play in and how many cards they buy they can win UP TO 100% cashback if you don't win, which makes the deal sound a bit more realistic! So... you can win £100 for 1p games at BingoStreet, £200 for 2p games at Tasty, £300 for 3p games at RedBus, £400 for 4p games at Posh and £500 for 5p games at Wink from 26th December until the 30th December- So I know what I'll be doing on my Christmas holidays!

I found a breakdown of the games, all of them start at 10pm:

BingoStreet- Monday 26th December
Tasty- Tuesday 27th December
Redbus- Wednesday 28th December
Posh- Thursday 29th December
Wink- Friday 30th December

So here's the bit I wanted to know about, cashback:

Buy cards on 1 site and get 10% cashback if you don't win
Buy cards on 2 sites and get 25% cashback if you don't win
Buy cards on 3 sites and get 50% cashback if you don't win
Buy cards on 4 sites and get 75% cashback if you don't win
Buy cards on all 5 sites and get 100% cashback if you don't win

It sounds pretty good but I did think if you even win about £1 then that counts as a win so it's not a bulletproof promotion but then if it was it would be too good to be true! I thought it was a pretty good deal though, just need to find one to keep me entertained in the run up to Christmas!
