Three Civilizations: Bonus Combo

Three Civilizations: Bonus Combo is an ancient-worlds slot from NetGame, released on 15 July 2026. It plays on a 5x4 grid with 40 lines, returns 96.23% at medium volatility and takes bets from 0.20 to 100. The top prize is 2,000x the bet – and for once that figure is not hidden in the maths, because it is the Grand jackpot on the wall.

A Volcanic Plain At Dusk

The reels sit in a slab of carved stone on a purple plain with lava glowing in the cracks and jagged peaks on the horizon. The THREE CIVILIZATIONS logo sits in the top left above the jackpot ladder, and three glowing orbs hang across the top of the frame like moons.

The symbols mix the civilisations together: a golden WILD plaque, a stepped pyramid, a pharaoh, a jade jaguar, a red ceremonial headdress and a red flower, with Q, K and J carved into stone underneath.

Extra, Hyper, Ultra

The three orbs above the grid are labelled, and they are the game’s organising idea: EXTRA in red, HYPER in green and ULTRA in yellow. The rules screen explains what they are for in a single line: they “may activate Rapid Link Bonus with a unique effect”.

Three different triggers into the same bonus, each bending it in its own direction, is a neater idea than the usual single scatter. It also means the orbs are worth watching in the base game even when nothing else is happening.

The Paytable

The rules screen prints the values at your selected stake. At a bet of 10.00, for five, four and three of a kind:

Wild – 75.00 / 25.00 / 3.00
Pyramid – 62.50 / 20.00 / 2.50
Pharaoh – 50.00 / 12.50 / 2.50
Headdress, jaguar and flower – 40.00 / 10.00 / 1.00

Five wilds are worth 7.5x the bet, and the wild is the best-paying symbol in its own right – not merely a substitute. The rules add that it “replaces all symbols except pay scatters” and “appears on all reels”, with no reel restriction of the kind many studios impose.

Four Jackpots, And The Grand Is The Ceiling

The ladder down the left edge reads, at our 10.00 bet:

GRAND – 20,000, or 2,000x
MAJOR – 5,000, or 500x
MINOR – 500, or 50x
MINI – 100, or 10x

The Grand at 2,000x is exactly the game’s published maximum win. That is rarer than it sounds – most jackpot slots put the ceiling well above the top plaque, so the advertised number is unreachable through the ladder alone. Here the two are the same thing, which makes the target unusually concrete.

Inside The Rapid Link

When the bonus starts the symbols vanish and the grid becomes a field of carved stone tiles with coins landing on it. Our boards carried values of 10 FUN and 50 FUN at a 10.00 bet – 1x and 5x the stake per coin – with a 150 FUN orb sitting in the row above.

Four blue bars appear across the top of the grid, and they are the most interesting thing on the screen. Each one reads as a target and a reward:

4 coins → 6
8 coins → 6
12 coins → 6
16 coins → 6

Four separate collection milestones, each awarding the same six of something – almost certainly additional respins, since slot catalogues list respins, locked reels and Lock It Link among the features. Reaching all four means twenty-four extra chances on top of the original round.

A Round That Paid Three Times The Balance

The credit meter tracks the whole thing. Our balance stood at 970.00 in the base game, dropped to 719.50 as the session went on, and read 2,195.50 once the Rapid Link round had finished – a gain of nearly 1,500 at a 10.00 bet, or roughly 150x.

That is what a medium-volatility game with a 2,000x ceiling looks like when the bonus behaves: not a life-changing result, but one that pays for a long stretch of base spins.

Forty Lines On Twenty Positions

A 5x4 grid holds twenty positions and this game runs forty lines through them – two paths per position, which is generous and keeps the small wins frequent. It is why our wild-heavy base spin paid 15.00 at a 10.00 bet from what looked like a fairly ordinary board.

It also explains why the paytable can stop at 7.5x for the best symbol. With forty lines to fund and four jackpots on the wall, the individual values have to stay modest.

The Wild Appears On Every Reel

Two details in the wild’s rule line are worth separating out, because studios usually restrict at least one of them. First, it appears on all reels – there is no “reels 2, 3 and 4 only” clause of the kind that quietly halves a wild’s usefulness elsewhere. Second, it is the highest-paying symbol in the game at 75.00 for five, ahead of the pyramid at 62.50.

Put together, that makes the wild genuinely valuable rather than merely helpful. A wild landing on the first reel can start a combination on its own, and a line of five wilds pays more than a line of any real symbol.

The Coin Values Are Modest

One expectation to set before you play. The coins we saw in the Rapid Link round were worth 1x and 5x the stake, with a 15x orb above the grid – respectable, but a long way from the 20x and 50x coins you find on the heavier Hold and Win games elsewhere on this site.

That is consistent with the 2,000x ceiling. This is a game that fills its board often and pays sensibly, rather than one that empties your balance while you wait for a single enormous coin.

What The Bet Changes

Everything scales with the stake. Our screenshots were taken at 10.00. At the 0.20 minimum the Grand is worth 400 and a 50 coin becomes 1.00; at the 100 maximum the Grand is 200,000 and five wilds pay 750. The multiples – 2,000x, 500x, 50x, 10x – hold at every level.

More From NetGame

NetGame builds most of its catalogue around Hold and Link rounds with jackpot ladders. Genie’s Chest Hold n Link uses the same coin-collection structure on an Arabian theme, and the studio’s wider range sticks closely to the formula: a modest paytable, a four-rung ladder, and everything interesting happening once the symbols clear off the grid.

Who It Is For

Three Civilizations: Bonus Combo is for players who like a clear target. The Grand jackpot and the maximum win are the same number, the four collection milestones are printed on screen during the round, and the three orbs give the bonus three different flavours rather than one. A 96.23% return at medium volatility makes the base game perfectly comfortable, and our single Rapid Link round was worth around 150x the stake. All six casinos we checked carry it.
