Yggdrasil Gaming · 2020Overview
Vault of Fortune is Yggdrasil's 5×3 heist slot with 20 fixed paylines and a 96.01% RTP. Land matching symbols across the grid to build wins; trigger free spins to unlock the multiplier climb that drives the big payouts.
How it plays
Spin from £0.10 to £100 per turn on a standard 5×3 reel set. Hits land regularly enough on the 20 fixed lines, but volatility is high — expect long droughts before the feature fires. When it does, that's where the 11,000x ceiling lives.
The bonus round
Free spins arrive when you land the scatter trigger. Once active, multipliers climb with each winning spin, stacking the potential payout. The longer the free-spin run, the higher the multiplier goes — and that's where the 11,000x win is built.
Who it's for
High-volatility players who enjoy extended dry spells for the payoff of one monster free-spin session, and who can stomach a 20-line grid without needing constant small wins.
Avoid if
You chase frequent payouts or play on tight bankrolls — Vault of Fortune's swings are brutal and can drain a session budget fast.

Land the scatter symbol to unlock free spins. Once active, each winning spin climbs a multiplier meter — that's where the big payouts accumulate.
It's in the maths — fully achievable on a max-multiplier free-spin run, but statistically rare. High volatility means you'll chase it longer than in lower-variance games.
