Avalon is a cool free spins slot. The bonus round tends to pay quite handsomely with the average payout being 40x bet I’d guess. It retriggers a fair bit too. During normal play the wins are small and frequent so its hard to go up by much without the free spins, but conversely it goes down slowly. Also worth noting hat you get an extra wild symbol during the free spins! Avalon is a good fun slot IMO and keeps you going – especially good for lower rollers.
