Free spins are extended one spin at a time: every spin in which a Roaming Wild is part of a winning payline adds one more. Thirty-nine of the 44 natural bonuses got at least one, 315 extensions in all, and round 4504 grew from 10 to 32 spins.

A EUR 125 Bonus Game buy grows from 10 to 18 free spins as Roaming Wilds climb to x5, ending on a TOTAL WIN of 127.50 · Recorded in a separate browser session, outside the statistical samples.

Griffin’s Gold – Reborn plays nine fixed paylines on a 5x3 grid; every test round cost EUR 1.00. Each line pays its longest run counted from reel one. Five griffins pay 150x the bet, five golden griffin statues 50x, the lyre 25x, the feather 22.5x and the crossbow 20x, and the royals from 15x for five aces down to 10x for five tens.

Outside the bonus the Griffin Emblem works as both Wild and Scatter: three of them pay 2x the bet and open the Bonus Game with 10 free spins, while four pay 20x and five 200x.

Free spins bring Roaming Wilds that stay for the rest of the bonus and move to a neighbouring position before each spin. Any spin in which a Roaming Wild is part of a winning payline adds one free spin, each such wild raises its own multiplier by one, and wilds sharing a line multiply together, so a x5 and a x5 make x25.

Thunderkick lists 96.14% RTP and a 22,222x win cap, with bets from EUR 0.10 to EUR 100. The Bonus Game is also sold for 125x the bet at 96.50%, the option used for the fifty test purchases.

Verdict

Wilds multiply each other

Thirty-six paylines in the 44 natural bonuses were multiplied above x5, which takes at least two Roaming Wilds on one line, and they paid EUR 2,018.50, 50.3% of all free spins money. Lines at x2 to x5 added EUR 1,732.50, while 268 lines paid at x1 brought only EUR 259. A single wild never went above x5 in 94 bonuses, so the big totals came from wilds sharing a line: x25 when two x5 wilds lined up.

Round 4504 shows it best. The bonus ran to 32 spins, its wilds paired up at x25, and on spin 22 five aces at x25 paid EUR 375 of the spin's EUR 377.50, the round ending at 768x the stake.

Purchases leaned on the same lines even harder: 61 lines above x5 paid 57.5% of the bought free spins money, and ticket 50 hit a x60 line from three wilds, EUR 750 of its EUR 1,220. Over fifty tickets the purchases returned 110.15% of the EUR 6,250 spent.

Measured upsides
  • Lines multiplied past x5 paid 50.3% of natural free spins money
  • Extensions pushed 39 of 44 natural bonuses past their opening ten spins
  • Ticket 50 paid EUR 1,220 with a x60 line from three wilds
Measured downsides
  • Free spins lines paid at x1, 268 of them, brought only EUR 259
  • A single Roaming Wild never climbed past x5
  • Below-price returns came on 30 of the fifty EUR 125 tickets

FAQ

5 questions · answered from the log
How do Roaming Wilds work in Griffin’s Gold – Reborn?
Lab answer

They stay on the reels for the whole bonus, move one position before each spin, gain one multiplier step whenever they help a win and multiply each other on a shared line; any spin in which they help a win adds one free spin. Lines multiplied past x5 by two or more of them paid 50.3% of natural free spins money in this test.

Which Griffin’s Gold round paid the most over 10,000 spins?
Lab answer

Round 4504, worth 768x the EUR 1.00 stake: 32 free spins, Roaming Wilds paired at x25, and one spin on which five aces at x25 paid EUR 375. Among purchases, ticket 50 paid EUR 1,220 after a three-wild x60 line.

Is it worth paying 125x for the Griffin’s Gold Bonus Game?
Lab answer

Yes, over these fifty tickets, though one of them made the difference: they returned 110.15%, EUR 6,884.50 for EUR 6,250, while the other 49 without ticket 50 returned 92.48%. The median ticket paid EUR 74.75, and 30 of 50 came in under the price.

Without a purchase, how regularly did the Bonus Game come?
Lab answer

There were 44 natural bonuses in 10,000 rounds, about 4.4 per 1,000 (4.4 bHz). They averaged 17.16 spins and 91.14x the stake, with a median of 43.75x.

What held the Griffin’s Gold demo to 88.53%?
Lab answer

Mostly the spread of bonus results: a few paired-wild bonuses, led by round 4504 at 768x, carry much of the return, while the median natural bonus paid 43.75x. The approximate 95% CI around 88.53% runs from 65.5% to 111.56%.
