Grid State: 15 Positions total.
Initial State: 6 Triggering Moons locked. 3 Respins granted.
Mechanic: Each new Moon symbol locks and resets Respin counter to 3.
End Conditions: Respins exhaust OR all 15 positions filled with Moons.
Grand Prize: Filling all 15 positions awards the 1,000x Mega Jackpot.
Every new Moon locks in and resets the respin counter to 3. The feature runs until the respins are exhausted or all 15 positions are filled. At the end, all cash values on the Moons are added together, along with any Mini (30x) or Major (100x) jackpot. Filling all 15 positions awards the 1,000x Mega Jackpot on top of the accumulated cash values, which is how the round reaches the 2,500x ceiling.
On buying the bonus. Unlike many newer Pragmatic Play titles, the standard version of Wolf Gold has no feature buy. There is no Wolf Gold bonus buy button to press, so both rounds must trigger organically from base-game spins. Purchase options only show up in later hybrid variations of the series, not in the original Hold & Win build that sits in Irish casino lobbies. If a site advertises a bonus buy on this title, check which version you are actually loading.
