Bgo has a couple of levels to the free spins strategy.
First up make sure you’re using Bookie Monster to get the best offer and don’t lock yourself into a lower tier offer without a good reason.
To start with you get your no deposit free spins on Starburst to start with. Not the best game to get free spins on but not the worst either. Once you play through these you’ll need to wager your winnings. The bgo wagering requirements are pretty low but they don’t count slot offers as a high percentage of wagering done. Best strategy for this is to pick a good popular slot with a good return. Something like Wild Gambler or Frankie Dettori’s Magic Seven Jackpot (both of which bgo have).
Once you’ve completed the no deposit spins bgo offers a great 200% boost to £200 for the first deposit. A full £200 deposit would be needed to make the most from this but you can pick the stakes to suit your bankroll. Even a lower deposit is still worth doing for a good offer. On top of the deposit bonus you get 180 free spins.
These bgo free spins are spread over 9 days (that’s 20 free spins a day) and they all have their own unique wagering requirements which can stack. So to make the most from this offer you should be using your 20 free spins each day and completing the wagering on them or busting out. You don’t want to leave wagering half done or part of a bonus balance left over for the next day. For these I would suggest higher stake spins over small stake grinding on a jackpot game like Gladiator Jackpot or Plenty O’ Fortune but you could try small stake grinding if you wanted.
The only other strategy for free spins is to get as much as you can out of them which means doing as many as you can. The more free spins you take the bigger the chance of hitting a big win. If you check the Bookie Monster tool every couple of days or so it’s constantly updating as new offers are added so you’ll always have something to do.
