REC · NATURAL TRIGGER

Three Sea Mine Scatters open the Shark Bonus, the multiplier climbs from x1 to x4 as the Mystery Stacks run out, and the round closes on 4.00. Recorded in a separate browser session, outside the statistical samples.

Across the whole run the 42 natural bonuses split into 20 under 20x, 5 between 20x and 50x, 11 between 50x and 100x and 6 at 100x or more, and together they made up 33% of everything the game returned. The wait between two triggers ran from 4 to 1,297 spins. Payout figures here are FS-only, in ordinary stakes; the trigger payout is excluded.

The free spins have no fixed length: each extra Sea Mine Scatter adds +1 to the feature, and every +1 nudges the Mystery Stacks up one position. Twenty-two of the 42 natural bonuses lasted five spins, eleven ran ten or more, and round 1553 went to 21.

Razor Shark pays on 20 fixed lines across five reels of four rows, and each test spin staked FUN 2.00. At that bet five Wild sharks pay 50x, the orange shark 25x, the pink one 20x, the green 7.5x and the blue 5x, while five cameras, masks, fins or air tanks pay 2.5x. Every symbol except the Sea Mine Scatter can be replaced by the Wild.

Mystery Stacks, four symbols tall, can land on any reel and start the Nudge & Reveal Feature: the stacks open into one paying symbol or into Golden Sharks. Golden Sharks start the Razor Reveal, in which every position of the stack spins into a Bet Multiplier Coin or a Scatter.

Three Sea Mine Scatters anywhere start the Free Games Feature, with Mystery Stacks filling the second and fourth reels. Each Nudge & Reveal lifts a win multiplier, x1 at the start, by one step, and the bonus continues until no Mystery Stack is left in view.

The build in the demo reports a 96.7% RTP and has no feature buy; its smallest total bet is FUN 0.10, its largest FUN 100.

Verdict

Most bonuses stopped at x4

Twenty-two of the 42 natural bonuses ran out of Mystery Stacks after five spins with the multiplier stopped at x4, and they averaged 13.37x the stake, trigger spin included; two of them, rounds 7270 and 7500, paid nothing at all. The 20 that kept revealing stacks past x4 averaged 119.81x a round and brought 89.1% of the bonus-round money. Ten bonuses, round 7027 among them, did not start from Sea Mines on the reels at all: their Scatters came out of a Golden Shark reveal. A long bonus was not always a rich one, though: round 1553 ran 21 spins and reached x19, yet paid 37.8x.

Round 7027 was the strongest bonus at 780.5x. Its multiplier climbed to x10 over 12 spins, a Golden Shark reveal added coins along the way, and the sixth spin alone paid FUN 800.

The single best round of the series came from the base game. Round 2119 drew a 1,000x Bet Multiplier Coin from a Golden Shark reveal and paid 1,016x, more than any bonus. Golden Shark rounds outside the free spins, 102 of them, averaged 20.41x; leaving round 2119 aside, the other 101 came to 10.56x on average. Golden Shark coins across all base spins, bonus triggers included, made up 26.8% of all payouts.

Line wins in the base game returned 42.5% of everything paid, more than the free spins, which arrived once per 238.1 rounds.

Measured upsides
  • Past x4, the multiplier lifted 20 bonuses to 119.81x a round on average
  • A 1,000x Golden Shark coin made round 2119 worth 1,016x
  • An x10 multiplier lifted round 7027 to 780.5x
Measured downsides
  • Five spins at x4 was the whole bonus 22 times, worth 13.37x a round on average
  • Two bonuses, rounds 7270 and 7500, paid nothing
  • Of 346 base-game Golden Shark coins, 263 were worth 1x or 2x the bet

One test run so far: a single session of the base game on the official demo server, every request and response logged; the game offers no bonus purchase, so every feature in the sample came from ordinary spins. When the game is tested again, the new run is added here and the figures on this page combine all runs into one sample.

FAQ

6 questions · answered from the log
In Razor Shark free spins, what makes the multiplier climb?
Lab answer

Each Nudge & Reveal adds one step to a multiplier that begins at x1, and the bonus lasts while Mystery Stacks remain in view. In this test 22 of 42 bonuses stopped at x4 after five spins; the highest multiplier was x19, on round 1553.

Golden Shark reveals: what can they pay?
Lab answer

Golden Sharks start the Razor Reveal, which turns each stack position into a Bet Multiplier Coin or a Scatter. The 346 coins logged in the base game ranged from 1x to 1,000x the bet; 263 of them were 1x or 2x, and the single 1,000x coin paid FUN 2,000 on round 2119.

Did any Razor Shark bonus pay nothing?
Lab answer

Yes. Rounds 7270 and 7500 paid nothing at all, and the five free spins of round 6059 also paid 0, its 5x coming from coins on the trigger spin. The 22 bonuses that stopped at five spins averaged 13.37x a round, trigger spin included.

Between two Razor Shark bonuses, what was the usual wait?
Lab answer

Over 10,000 rounds there were 42 natural bonuses, one per 238.1 rounds, about 4.2 per 1,000 (4.2 bHz). The longest wait ran 1,297 spins, from round 3858 to round 5155.

Does Razor Shark let you buy the bonus?
Lab answer

No. Regular spins started every one of the 42 bonuses, with no feature buy on offer: 32 came from Sea Mines landing on the reels and 10 from Scatters revealed by a Golden Shark.

Is 82.76% the real Razor Shark RTP?
Lab answer

No. One sample of 10,000 spins produced it, and a few large rounds hold much of it: taking out round 7027, the best bonus, leaves 74.96% for the other 9,999 rounds. The approximate 95% CI around 82.76%, from 55.43% to 110.09%, includes the listed 96.7%.
