I Havnt used any of the casinos you mentioned , i have stuck With Videoslots (best layout and best selection of games imo) Mr Vegas its sister site,Captain Spins which gives you some kind of bonus every deposit (Spins or a % of Deposit) although recently the % deposits have dropped from the odd 50% down to 20 or even 10%,I also play at Sky Vegas , Betfred Will Hill and a few more lol the first 3 casinos i mentioned all have very fast withdrawals if you manage to accumulate enough to withdraw, Few years back i took 100% bonus a few times £40 in £40 bonus from Ladbrokes and 3 times i completed £1400 wagering playing a game Called Halloween Fortune withdrew £500 twice and £300 twice ,Not too many casinos have the game now but if they have try wagering out on this game,its only an opinion but i am taking it from my past experiences with the game, it wont always beat a wager but worth a try,(and on the Game Lil Devil i have had my biggest X wins on the game playing 10 or 20p, 14,000x 7000x and 5000x all on 10p , i treat the Heartstopper like a normal Bonus as all my best wins have came from a normal bonus and because of this i dont get let down when i get a poor bonus like My Zero pence Heartstopper
