Links of Ra CASHINGO King Millions Slot Review
Charging players 4.50% of their return for a shot at a progressive is a tax, and Links of Ra CASHINGO King Millions is the rare game honest enough to print the bill on its own RTP screen. Most slots bury the jackpot levy in a single figure. This one itemises it: 86.00% for the reels, 4.50% for the King Millions pot, 90.50% all told. What you’re being asked to accept is a base game stripped back to pay for a lottery ticket on top.
That base game is a 5×4 grid with 40 fixed paylines, stakes from 0.20 to 20.00, and volatility rated Very High. Slingshot Studios are the builders, and this is recognisably their territory. We’ve covered Links of Ra Cashingo and Links of Ra before, alongside Candy Combo Power Combo King Millions, which runs the same King Millions progressive layer.
When we reviewed Links of Ra Cashingo in June 2025, we praised the Cashingo collection mechanic for its depth but noted the intervals between bonuses could stretch. This one stacks even more machinery on top.
Base Game & Features
The base game is a 5×4 grid with 40 fixed paylines, paying left to right from the first reel. Only the highest win is paid per line. It’s standard line-pay scaffolding, and the symbol values tell you the lines aren’t the main event.
Paytable
Wins are multiples of the line bet. Five of the top symbol returns 3x, which frames the ceiling neatly:
- Pharaoh/Anubis (red/gold figure): 3 pays 0.8x, 4 pays 1.5x, 5 pays 3x
- Lion/Sphinx (green) and ram-headed figure (purple): 3 pays 0.6x, 4 pays 1.2x, 5 pays 2.5x
- Red gem and gold/yellow gem: 3 pays 0.5x, 4 pays 1x, 5 pays 1.8x
- Teal triangle gem and purple gem: 3 pays 0.4x, 4 pays 0.8x
Wilds substitute for everything except Scatters and Coins, and can form their own winning combinations. Scatters pay anywhere and multiply by the total bet. Neither is where the money lives.
Power Stacks™
Power Stacks trigger randomly on every spin, base game and Free Spins alike. Stacked symbols get added to all reels. In the base game, anything except Scatters, Wilds and Coins can stack; in Free Spins it’s Wilds and Coins only.
CASHINGO™ Grid
CASHINGO is the first of the three collection systems. Cash and Jackpot Coins that land transfer to a corresponding position on a persistent CASHINGO grid. Land more Cash Coins in the same position and their values stack up, from 0.5x through to 3x.
Complete a horizontal, vertical or corner-to-corner diagonal set of coins and you win the cash value of that set. Up to four sets can complete on a single spin, and intersecting Cash Coins contribute to each. Only coins that form part of a winning set are removed, so the grid accumulates over time.
CASHINGO™ Jackpots
- GRAND: 5,000x
- MAJOR: 500x
- MINOR: 50x
- MINI: 15x
All jackpot values multiply by the total bet, and only one of each can sit on the grid at once. Completing a set containing one or more Jackpot Coins awards the associated jackpot. That’s the route to the big money in the base game.
King Millions™ Tokens
The third meter. One King Millions token can land per spin, and collecting them grants a chance of randomly triggering the King Millions Bonus Wheel. The chance increases with your bet size. The collection animation is, in the game’s own words, purely for visual entertainment.
Links of Ra CASHINGO King Millions: ULTRA Link&Win™, Free Spins & King Millions™ Bonus
ULTRA Link&Win™
Land six or more Coin symbols anywhere and the ULTRA Link&Win feature triggers: three free respins with the triggering coins held in place. Every new coin that lands is held and resets the respins back to three. The round ends when respins run out or the grid fills completely.
Four or five coins don’t trigger the feature outright; they fill a meter instead. Fill the meter to the relevant level and the next trigger launches in one of three enhanced modes:
- Max Mode: starts with all 3 additional rows active
- Multiplier Mode: 3 additional rows plus a guaranteed Persistent 2x Multiplier Booster Coin
- Collect Mode: 3 additional rows plus a guaranteed Persistent Cash Collect Booster Coin
Booster Coins
Four boosters can land during the feature, and they’re what turn a routine round into something bigger:
- Persistent Cash Collect Booster: collects the sum of all Cash Coins into a total on every spin, retriggering until the feature ends. Jackpots can’t be collected
- Persistent 2x Multiplier Booster: randomly doubles up to 4 Cash Coins every spin. Jackpots can’t be doubled
- Unlock Booster: activates 1 additional row, up to 3
- Extra Chance Booster: awards 1 free respin when the respins hit zero
Cash Coins pay in any position at the end of the feature, at values from 0.5x up to 12x. Jackpot Coins work differently: each counts down once per spin, and if the countdown completes before the feature ends, the jackpot is awarded. The same GRAND 5,000x, MAJOR 500x, MINOR 50x and MINI 15x ladder applies.
HOT MODE™
HOT MODE can trigger on any base game spin and lowers the stakes for entry: a free Coin is held on the collect meter, and the number needed for the ULTRA Link&Win meter or trigger drops by one. Five coins will launch the feature, three or four feed the meter.
It ends after a random number of spins or when a feature triggers. Base game only.
Free Spins
Three, four or five Scatters anywhere award 10 Free Spins. On every free spin, Wild or Coin symbols are Power Stacked, which matters more than it sounds: it’s the fast lane to both the CASHINGO grid and the ULTRA Link&Win trigger. The round plays out automatically and cannot be retriggered.
King Millions™ Bonus Wheel
Collect enough tokens and you get a spin of the wheel, with the two progressives – Grand and Major – sitting alongside cash prizes between 7x and 100x the bet. The progressives are funded by that 4.50% RTP contribution and rise with play. Trigger chance scales with bet size, and only one feature can fire on any given spin. A win resets the token pot.
Our Honest Verdict
Overall Rating: 6.6/10
The trade here is explicit: hand over 4.50% of your expected return, in exchange for a progressive you’re statistically unlikely to win. That’s not a hidden cost or a design flaw, it’s the product. Everything else in the game is arranged around making that trade feel like something other than a subscription.
The meter-work mostly succeeds. The CASHINGO grid’s persistence is the best idea here, and the three ULTRA Link&Win modes give the collection a destination worth the wait. What the game does badly is the thing it makes you watch most: the reels themselves. A 3x ceiling on five-of-a-kind means line wins exist to keep you spinning between collections, not to pay you. On Very High volatility, with one spin in three paying anything, those stretches are felt.
So take a side. If you want your RTP in the base game, play the earlier Links of Ra Cashingo, which does the core collection job on better terms. This one suits jackpot chasers and players who enjoy watching meters fill for their own sake. For them, it’s a richly built machine. For anyone else, it’s a lean paytable with a raffle attached.
