Howling Riches Power Combo Slot Review
On the sunny cartoon outskirts of a storybook city, a wolf in a shirt and blue tie leans in past three pastel banks, teal, gold and pink, half-hiding a gold-rimmed wheel behind the reel frame. Howling Riches Power Combo hides its best idea the same way: the bonus round can be rebuilt into several genuinely different features before it even begins, and which one you get depends on a detail most games would never think to make matter.
It’s a 5×3 grid with 40 paylines, running at 96.25% RTP with medium volatility and a hit rate of 24.39%, so roughly one spin in four connects. Stakes run from 0.10 to 30.00. It comes from Infinity Dragon Studios, the studio behind Poseidon: Trident’s Riches Power Combo and Cluck N’ Fortunes Power Combo, and the family resemblance is strong.
Base Game & Features
Wins pay left to right across 40 fixed paylines, with the number of lines locked and the paytable priced on the initial bet. The premium symbols are two pigs, a large one and a small one, followed by a toolbox and wrench, a chain and lock, and the royals.
The full paytable, as multiples of the total bet:
- Both pigs: 0.1x for two, 0.2x for three and 0.75x for four; the large pig tops out at 2x for five, the small pig at 1.5x
- Toolbox / wrench: 0.15x for three, 0.6x for four, 1.25x for five
- Chain and lock / A: 0.15x for three, 0.5x for four, 1x for five
- K, Q, J, 10: 0.1x for three, 0.25x for four, 0.75x for five
The Wild substitutes for everything except Scatters, the Bonus Wheel, Collect, Coin and Prize symbols, and appears in the base game only.
Base Game Instant Collect
Coin and Prize symbols land on all five reels. When a Collect symbol lands on reel one or reel five, every Coin and Prize on screen is paid out on the spot. It’s a simple system, and it keeps the reels worth watching between bonuses.
Bonus Wheel Symbol
Bonus Wheel symbols can land on any reel, and each one is banked in a meter along the bottom of the screen. Collect one on every reel to spell B.O.N.U.S and the Bonus Wheel Feature triggers, awarding 3 spins of a wheel that can pay out up to 3 Power Combos, starting Link&Win Coins, or Bonus Prizes.
Howling Riches Power Combo Bonus Features
The headline attraction is Link&Win, a hold-and-respin round that starts with 3 spins and 3 Coin symbols already locked in place. Every additional Coin that lands holds and resets the respins to 3. Filling every position wins the Grand at 5,000x the total bet, with Major at 100x and Minor at 25x available along the way, and everything won in the round is added to base game wins.
What makes it more than a standard hold-and-win is the scatter system. Power Combo Scatters come in red, blue and yellow, and each colour switches on its own version of the round.
Red Scatter: Multi Boost
The reels divide into four coloured zones, each carrying a multiplier of 2x, 3x, 4x or 5x chosen at random, with the zone sizes shuffled on every trigger. Fill a zone by the end of the round and all prizes inside it are multiplied up and added to the total.
The Siren symbol is the upgrade mechanic: land one in a zone and its multiplier climbs by 1x, up to a maximum of 10x, after which the Siren turns into a Coin and the spin count resets to 3. Multiple Sirens can land together or in succession.
Blue Scatter: Expanding Reels
The grid grows to a 5×5 reel set, adding positions to fill with Coins. It pairs particularly well with Multi Boost, which divides the expanded grid into six zones instead of four.
Yellow Scatter: Instant Collect
The Collect symbol can land on any reel during the round, and when it does, every Coin on screen is collected and paid immediately, with the respins resetting to 3. It removes the risk of a loaded board going unpaid.
Combined Power Combos
Triggering the round with more than one scatter colour combines their powers:
- Red + Yellow: Multi Boost with Instant Collect
- Red + Blue: Multi Boost with Expanding Reels
- Blue + Yellow: Expanding Reels with Instant Collect
- Red + Blue + Yellow: all three features at once
The split of the game’s return tells you how central this is: Multi Boost carries 8.38% of the RTP, Expanding Reels 9.48%, Instant Collect 8.34% and the Bonus Wheel 10.39%. The scatter collection itself is decorative, purely for show, with no influence on triggering anything.
Feature Buy
A buy button skips the wait and triggers Link&Win directly, priced as displayed and played at the current bet, though it’s switched off above a certain stake. Each version of the round can be bought separately.
- Buy Multi Boost: 96.75% RTP
- Buy Expanding Reels: 96.68% RTP
- Buy Instant Collect: 96.90% RTP
- Buy any two combined: 96.50-96.51% RTP
- Buy all three combined: 96.51% RTP
Every buy option returns more than the base game’s 96.25%, and the yellow Instant Collect buy is the richest of the lot at 96.90%.
Our Honest Verdict
Overall Rating: 7.8/10
Playing this one is a stake-out on a sunny street corner. Coins get scooped off the end reels, B.O.N.U.S letters tick along the bottom meter, and three coloured banks fill slowly at the top while the wolf waits everyone out. You sit through all of it for one reason: the round that follows, which changes shape depending on what set it off.
That scatter system is the strength. One hold-and-respin engine becomes three genuinely different rounds, and the combined versions layer them without muddle. The buys deserve credit too: every single one returns above the base game, which is rarer than it should be.
The weakness is everything between rounds. Those banks fill and flash and decide nothing, so the quiet spells look like progress without being any. This suits patient players who enjoy a long build towards a round that never plays the same way twice; anyone wanting action on every spin will find the wolf keeps long hours. When the piggy banks finally crack, the wait makes sense.
