This will work if you open a new account and sign up as a new account holder at a microgaming casino and have no deposit history at that casino. The theory is a that a new player to a casino wants to have a taste of winning and the percentage of payout is always higher for a new player and the casino doesnt know how you bet and what kind of amounts of credits you gamble with.
First sign up at a microgaming casino thats offering a good welcome bonus offer like spin palace, piggs casino or mummys gold and deposit as much as you can to get the best bonus (usually 100% up to £200). Next you have to wager this money 30x over(check terms and conditions to be sure, casinos vary slightly) which means if you deposit £100 get 100% bonus that gives you a bankroll of £200, and you have to make 30x£200 in bets which equals=£6000 (which is 6000 spins on a slot at £1 a spin basically) this seems alot but it isnt.
Now start by going to the video slot called DOGFATHER, this slot gives the feature bonus rounds quickly as a new player, play at between 0.40 and 0.80 a spin till you hit the feature (free spin round) then up your bet to max 1.00 a spin and keep going till you get the feature again. exit the machine. Go to the video slot Dolphins tale, and do the same, start at a medium bet 0.60 to 0.80 and get the feature, increase your bet and get the feature again, exit the slot. Should be going well and you would have made a nice dent in the playthrough requirments and have a good looking bankroll. Onto the big machines, the 9 line slots, rotate your play between Ladies Night. Spring break, Tally Ho and Summertime. Dont play Adventure palace, trust us. What you should be doing is playing at 0.90 a spin and from here you work out how many spins your taking to get through the playthrough requirements. Next you want to Cashout, dont get greedy just make the requirment even if youve only made £50 take it and move on to the next casino and do the same
