FluxPlays verdict
Our verdict
No, unless you will stay at one bet for a long session. The game keeps its best feature, a sticky wild whose multiplier grows with each consecutive win, behind a coin bar that fills slowly. We never reached even the first upgrade, so this verdict rests on the rules. Until the upgrades arrive, the base game leans on a modest paytable.
Who it suits
Play this if…
- Long-session players: progress is kept per bet level, so the upgrades reward staying at one stake
- Players who like a game that changes: the wild goes from single symbol to stacked, multiplied and sticky
- You enjoy a visible goal: the bar beside the reels shows exactly how far each upgrade is
Skip this if…
- Short-session players: a few dozen spins may never reach the first upgrade
- Bonus buyers: nothing can be bought, so every upgrade has to be earned
- Players who switch stakes often: each bet level keeps its own progress

Primate King: Full Review
In Primate King the wild gets better the longer you play: Gold Coins collected with the gorilla wild fill a progress bar, and three upgrades turn it stacked, then multiplied, then sticky. Red Tiger released this jungle game in March 2021, before the separate Primate King Megaways of 2022. It is built for patient players who stay at one stake, because the progress belongs to the bet level you play.

How Primate King works
The base game plays on five reels of four rows, and Red Tiger lists 30 lines. The Primate Wild substitutes for every paying symbol. Treasure chests top the paytable:
| Line pays at $1 | Six | Five | Four | Three |
|---|---|---|---|---|
| Treasure chest | $30.00 | $15.00 | $5.00 | $2.50 |
| Compass | $20.00 | $10.00 | $3.00 | $1.50 |
| Map | $12.00 | $6.00 | $2.00 | $1.00 |
| Snake | $6.00 | $3.00 | $1.00 | $0.50 |
| Four card suits | $1.20 to $3.00 | $0.60 to $1.50 | $0.20 to $0.50 | $0.10 to $0.20 |
The six-of-a-kind column is the clue to how the game develops. A sixth reel exists only after all three upgrades are unlocked, so those pays are out of reach for a new player. By the paytable, five chests on a line pay half of what six would.
The symbol pays at a 1.00 bet, with six-of-a-kind values. FluxPlays demo test, 2 November 2026.
How the Primate Wild upgrades work
Everything in the game runs through one bar to the right of the reels.
- While upgrades remain, Gold Coins can appear in the bottom right-hand corner of any symbol.
- Coins count only when they land on the same spin as a Primate Wild, and then they move into the progress bar.
- The bar unlocks three upgrades in order. Once all three are in, it becomes a sixth reel that carries only high-paying symbols.
The three upgrades
| Upgrade | What changes |
|---|---|
| 1 | The Primate Wild becomes a stacked 1x4 symbol, covering its whole reel |
| 2 | A random multiplier is added to the Primate Wild |
| 3 | The Primate Wild turns sticky. It stays until it has been part of at least one win and a losing spin follows, and each consecutive win it joins raises the win multiplier |

The first upgrade changes ordinary spins the most: a wild stacked over all four rows sits on every line that crosses its reel. The second adds a random multiplier, and the help gives no range for it. The third upgrade is the one the game is built around. A sticky wild that keeps winning keeps raising its multiplier, and it only leaves after a spin that pays nothing. Before our first spin the bar read 0/30, 0/60 and 0/90.

Primate Smash
The one feature the help does not tie to coins is Primate Smash. When a Primate Wild lands and the spin has no win, the gorilla may smash the reels: every low-paying symbol is removed, top-paying symbols fall into the gaps, and the spin ends with a guaranteed win. The help says he may, not that he will, and gives no rate for it. It is the base game's only rescue for a wild that would otherwise land for nothing, and nothing in the rules ties it to an upgrade.

Progress is kept per bet level, so changing your stake starts a different bar. For a demo session that matters: the upgrades reward long play at one bet, and a short session may never reach the first.
RTP, volatility and max win
Primate King's help pages leave RTP out. The 95.66% comes from the game's server settings and agrees with Red Tiger's game page, which also gives a hit frequency of 28.76%. Red Tiger shows volatility as an unlabelled gauge, and review sites agree on High.
Red Tiger's page and the game's own settings agree on a 3,800x maximum. Neither says which feature reaches it, but the sticky wild with its growing multiplier is the only part of the game designed for a long run of wins.

Played on Red Tiger's own demo launcher (build 4.0.1) on 2 November 2026, because the redtiger.com fan-site frame returned a server error that day; the launcher needs session tokens, so this page has no embedded demo. Credits carry no currency label; we count one credit as one dollar. All 100 spins at 1.00 from a 1,000.00 balance, Turbo on, with a fresh progress bar at that bet. The game has no buy or paid mode. The help screens, read in a second short session the same day and not counted here, state no RTP; 95.66% comes from the game's settings and matches Red Tiger's game page. Totals from the game server: $100.00 staked, $66.60 returned, ending at 966.60.
The bar never reached its first mark, so every spin we played used the plain Primate Wild, and no Primate Smash came either. The upgrades and the smash are described from the in-game help, captured after the logged spins. Wins came on 24 spins, the session opened with 12 losing spins in a row, and spin 88 paid $32.00, about half of everything the session returned. One hundred spins is a tiny sample for a game that is designed to change over hundreds.
Three treasure chests on the bottom row; that spin paid 5.00 in our second session. FluxPlays demo test, 2 November 2026.
Is Primate King worth playing?
No, unless you plan to stay at one bet for a long time. The game saves its best features behind a coin bar, and until the first upgrade arrives you are playing a 30-line game with a modest paytable, a hit frequency under 30% and Primate Smash as the only help. Once the sticky multiplier wild is unlocked, the picture changes, but getting there is the whole commitment.
Pick Cocks and Robbers if you want Red Tiger wilds that pay off on the spin they land, collecting animals for a prize that climbs with the count. Pick Primate King if a wild that grows stronger across a long session appeals more.
In the demo, keep the bet fixed and watch the coin bar. How fast it fills at one stake tells you whether the upgrades are realistic for the way you play.
Frequently Asked Questions
How do you unlock the wild upgrades in Primate King?+
Collect Gold Coins. They appear on symbols while upgrades remain and count only when they land on the same spin as a Primate Wild. The bar unlocks a stacked wild, then a multiplier, then a sticky wild, and progress is kept per bet level. Our 100 spins did not reach the first upgrade.
What does the sticky Primate Wild do?+
After the third upgrade, a Primate Wild that lands stays on the reels until it has joined at least one win and a losing spin follows. Each consecutive win it is part of raises the win multiplier, so a run of wins keeps getting bigger until a spin pays nothing.
What happens when all three upgrades are unlocked in Primate King?+
The progress bar is no longer needed, so it turns into a sixth reel on which only high-paying symbols land: the treasure chest, compass, map and snake. That opens the six-of-a-kind pays, and the Primate Wild keeps all three upgrades: stacked, multiplied and sticky.
What is Primate Smash in Primate King?+
A base-game rescue that the rules do not tie to any upgrade. When the Primate Wild lands on a spin with no win, he may smash the reels, clearing every low-paying symbol so top-paying symbols drop in and the spin pays. The rules give no rate for it, and it did not happen in our test.
What is the max win in Primate King?+
Wins are capped at 3,800x the bet in the game's settings, the figure Red Tiger's game page gives too. The separate Primate King Megaways, released in 2022, lists 30,000x, so check which game you are playing. In Primate King the sticky multiplier wild is the feature built for long winning runs.
