Across 430 spins at 1.00, the balance of 1,000.00 never once went above where it started and settled at 782.60. Stacked 7s, a wild confined to the middle three reels and a single eight-spin feature worth 26x did not change that much.
The action happens on a 5x4 grid. All paying symbols appear stacked on the reels. Winning combos are created across 40 fixed paylines when three or more identical symbols land from left to right, beginning on reel 1. I played 430 spins at a 1.00 stake, and my balance went from 1,000.00 to 782.60.
Theoretical RTP is 95%. My session returned 49.4%, with 430.00 wagered and 212.60 won. Volatility is high at 5 out of 6, and stakes run from 0.20 to 100 credits per spin. Only 87 of my 430 spins paid anything, and 45 of those paid less than the stake.
Reading up on the paytable shows eight paying symbols, a wild and a Bonus symbol, and beginning with the lower value payout symbols, I ran across grapes, plums, oranges, watermelons, and bells at the lowest end. Bells and watermelons pay 5x the stake for five on a line, while grapes, plums and oranges pay 2.5x. Fire 7s, Red 7s, and Blue 7s are the three top-tier symbols. Five Red 7s pay 7.5x the stake and five Blue 7s pay 6x. The Fire 7s are worth 25 times the stake for a string of five. Three Fire 7s return 1.5x the stake and four return 5x.
The wild substitutes for all paying symbols except the Bonus, and wilds only land, stacked, on reels 2, 3 and 4. My biggest base-game hit was 47.00 on spin 382, which is 47x the stake.
Hold an eye out for the Bonus symbol, which lands on reels 1, 3 and 5. In 430 spins I triggered the feature once, on spin 347. Landing three triggers the Free Spins feature, and eight free spins are granted. My one trigger's 8 free spins paid 26.00, which is 26x the stake.
Throughout the feature, the reels carry only the wild and the three 7s, and the Bonus symbol does not appear. So the free spins cannot be retriggered. The Free Spins accounted for 12% of everything I won in the session.
The Minty Summary: Stacked Fire 7s is a hard, volatile slot. Over my session the balance never climbed above its 1,000.00 starting point, and the longest run without a win lasted 25 spins, ending on spin 76.
One of the major hurdles is triggering free spins, which can only be achieved by landing three Bonus symbols on reels 1, 3 and 5. The Gamble feature has a second wheel that offers a chance at up to 30 free spins, and it can be set to offer itself on any win of 5x the bet or more.
Up to 2,500 times their stake can be won by players.
