A volcanic fruit machine built on one trick: an erupting volcano wild that lands on any reel, stretches across its neighbors and turns the whole block wild. Three mystery jackpots tick above the reels.

Blow Fruits 40 Slot Overview
Take a plain fruit machine and drop a live volcano into the middle of it. That is Blow Fruits 40. Cherries, lemons, bells and a red 7 turn on a 5x4 grid, and the only thing that is not stock retro furniture is an erupting volcano marked WILD, which lands on any reel and blows outward across the positions around it until that whole patch of the grid is wild.
Nothing else happens. No scatter, no free spins, no bonus round, no buy button. Forty fixed lines, one wild that spreads, a red-or-black gamble on any win, and three mystery jackpots ticking above the reels on a slice of every bet. The volcano is also the top payer at 18.75x for five, so a stretched block that lands across busy lines is doing two jobs at once.
Fazi has run this idea before under the Blow name, with dynamite instead of lava doing the stretching. The volcanic version is the better-looking one.
Theme & Design
The backdrop is a hazy valley at sunset, orange sky bleeding down into brown ridges, and a cone on the left dribbles a thin ribbon of lava the entire time you play. Behind the reels sits cracked rock in a dark red so close to black that the fruit pops harder than it does on most retro cabinets. The symbol set is the usual crowd, drawn well: glossy twin cherries, a fat purple plum, a watermelon slice cut open to show the seeds, a gold bell trailing a red ribbon, and a chunky red 7 in a gold frame. A blue x2 coin badge sits on the left rail waiting for the gamble.
Three jackpot banners stripe the top in gold, blue and grey. The volcano is the only symbol that gets a proper animation, and it earns it: the cells it takes over turn into a sheet of molten orange with WILD stamped across every row it swallowed. Audio is thin, though. Standard chimes, a rumble on the eruption, nothing you would miss with the sound off.

Features & How They Work
The Stretching Wild
One volcano, any reel. When it drops it erupts into every neighbouring position, and all of those cells become wild and substitute for everything. A single hit can leave a three-by-three slab of lava sitting in the middle of the grid, which on a 5x4 layout is a serious chunk of the 40 lines covered at once. That is the whole engine of the game, and unlike most expanding wild designs it is not locked to the centre reels or to a bonus round.
Two eruptions on the same spin is where the paydays are. The wild is also the highest-paying symbol on the table, so a stretched block frequently pays as itself as well as completing everything around it.
Forty Fixed Lines
All 40 lines are always active and cannot be switched off, which is why the minimum bet is 0.40 rather than a penny. Combinations run left to right from the leftmost reel on adjacent reels only, the highest win alone is paid on each line, and wins across separate lines are added together. Bets run 0.40 up to 60.00.
Gold, Diamond and Platinum Jackpots
Three mystery progressives sit above the reels, each a fixed award plus an increment that grows from a percentage of every base-game bet. There is no trigger symbol and no qualifying combination. Each jackpot is assigned a hidden payout figure drawn on a uniform distribution between its starting and maximum value, and whoever pushes the meter past that figure takes it. Betting higher raises your chance on a given spin.
They are funded, not free: Gold contributes 0.06% of the RTP, Diamond 0.05% and Platinum 0.03%. That is 0.14% of the 96.59% total going to jackpots, which is modest as these things go, and it means the base paytable is barely diluted.
Red or Black Gamble
After any win the x2 button opens a card gamble. Pick red or black, guess right and the amount doubles, guess wrong and it is gone and the round is over. The ceiling is 50,000.00, which is far beyond anything the reels are likely to hand you at these bet levels, so in practice the limit never comes into play.

How Blow Fruits 40 Plays
Sessions here are flat in a way that suits some players and bores others. There is no meter filling, no scatter count building, nothing being saved up for later. Every spin is settled the instant the reels stop, and the only question that matters is whether a volcano showed up.
Most of the time it did not, and you are collecting 0.05 and 0.20 dribbles off cherries and lemons at the bottom of the pay tier. The low fruits share one payout row, so four of the nine symbols are functionally identical and stretches of play blur together. Then a volcano lands, the grid turns to lava, and the count jumps. Medium volatility describes it fairly - it does not go cold for hundreds of spins the way a modern bonus-hunt slot does, but the good spins are not life-changing either.
The jackpot meters do quiet work on the mood. Watching the Diamond figure creep up while you spin gives the session a second thing to be interested in, and since the trigger is random rather than earned, it never feels out of reach. Whether that is a hook or just wallpaper probably depends on how long you sit there.
Pros & Cons
Pros
- The stretching wild lands on all five reels, not just the middle ones, so any spin can turn into a big one
- Wild is also the top payer at 18.75x, so eruptions pay twice over
- Clean, fast, no menus or meters to learn - loads and plays in seconds
- Jackpot funding is light at 0.14% of RTP, leaving the paytable mostly intact
Cons
- The wild is the entire game; strip it out and there is nothing left but a payline counter
- Four of the nine symbols share the same tiny payouts, which makes the base game repetitive
- No max win is published anywhere, so the realistic ceiling is guesswork
- Sound design is forgettable
Is Blow Fruits 40 Worth Playing?
A one-mechanic slot that knows it is a one-mechanic slot. The stretching volcano is a good mechanic, freely placed, generous when it doubles up, and the lava-block animation gives it more punch than the dynamite version in Fazi's earlier Blow titles. The 96.59% RTP is decent for a fruit machine carrying progressives.
What holds it back is everything it chose not to build. Four identical low fruits, no second gear, and the total absence of a bonus round mean the ceiling on how interesting a session can get is set on spin one. Fazi builds for land-based-style venues and betting shops where that flatness is the point, and it shows.
