This is basically a 20 paylines slot with 5 reels. The minimum bet is 0.40 because 0.20 goes for the feature. When you sit to play the game you will see 3 extra mini slot versions of the game connected to the main slot. The first two reels of the main slot are connected to the first mini version, the central reel is connected to the central mini slot and the last two reels are connected to the third mini version.
Whenever a stacked reel of wilds land in the main slot it unlocks the corresponding extra slot and adds a multiplier. All symbols can come stacked in this game including wilds. The more wild reels you get the more the multiplier increases. On the last reel if a golden trumpet lands all the unlocked mini versions take a spin and all wins are multiplied accordingly. Also the trumpet can bring a multiplier of up to 5. This is then multiplied to the overall multiplier of the mini versions. For example if all 3 are unlocked and you have multipliers of 5, 10 and 20 and you get a trumpet with a 5 x multiplier the multipliers for that spin increase to 25, 50 and 100. If you are lucky to get this with a few reels of stacked wilds you are guaranteed a massive payout. If the bonus symbol lands on reels 1 and 5 you are awarded free spins without a reset to the mini slots. If a red trumpet lands on reel 5 you are awarded 5 euros and the slots reset so you start all over again.
I had some nice wins on this slot, but the first time I saw it was on a Youtube video some guy posted in a land based casino. All 3 slots unlocked and a 24 x multiplier on the last. He got a trumpet with a 5 x multiplier and 3 stacked reels of wilds with a roman emperor on the first. I didn’t see how much money he won but from the screaming I’m sure it was a lot.
