777 – Thunder Hits is a classic 3×3 fruit machine with only one bonus feature, Retro Bet. It has no free spins and wild symbols, so this is a genuine retro piece that will appeal to players who prefer this type of game. Based on my experience with 200 free spins in this video slot, it has a very high volatility.

As of today, 777 – Thunder Hits is the first game from Spinomenal in which I did not have any winnings for 38 spins in a row. I started recording my video (you can see it above) and had the first win only on the 39th spin.

Ultimately, I had a $16.40 profit. It was quite unexpected because the gameplay was steadily slack, and I thought it would end in a loss. Suddenly, I landed three 7s, which brought me the slot’s top prize of x3,000. My bet was minimal, as usual, at $0.01 per line, so the cash prize was $30. Without that single combo, I would have ended up seriously out of pocket.

What is a Retro Bet?

Spinomenal has many video slots with a Retro Bet add-on, which works differently in each case.

777- Thunder Hits accepts $0.05 to $50, in line with Spinomenal’s practice of integrating the $10 maximum line bet. All combinations award when three matching pics line up.

The best-paying pic is 7 – it awards x300, but a player can increase its payout tenfold by tapping a slider button at the top left and activating the Retro Bet. As a result, the video slot will deduct twice the normal bet on each spin. For example, I was going to play my test spins at the minimum 5-cent stake. After turning the Retro Bet on, I had to pay 10 cents for each spin.

How much can you win in 777 – Thunder Hits

The video slot also has low-paying symbols: cherries (x20), three kinds of BARs (x40 each) and bells (x40). All multipliers are applicable to the base bet, exclusive of the Retro Bet. For example, I wager $0.05, and each spin costs me $0.1 due to the Retro Bet. If I land three horseshoes, I will win $0.01 x 120 = $1.20.

Playing at $10 per line, I can win $30,000 for three 7s with the active Retro Bet.

My verdict

The video slot is excellent for retro game fans. If you are interested in modern feature-packed slots with five reels, 777 – Thunder Hits is not your fit. The highest award is $30,000. RTP ranges between 88.87% and 96.55%.
