@Winningbird – Dazza G does slots reviews every week on a Monday. I don’t like his attitude – pessimistic, impatient and moans while waiting for a feature to drop. To be taken with a pinch of salt. I still watch him sometimes though, to see what upcoming slots are coming from the various studios.
As for demo play, I don’t think that Dazza ever tried to keep that a secret imo. Every slot he reviews will start with a 1000 unit balance, the next slot starting back at 1000 again and so on. A few of the slots also have test mode where he can force a feature and numerous other set-ups.
