Fort Knox Da Vinci Diamonds: Tumble the Gallery and Hunt the Jackpot for up to 500x Wins

The Louvre and the Uffizi keep the originals, but IGT brings the next best thing onto a five-by-three grid in Fort Knox Da Vinci Diamonds.

The Renaissance gallery can also be a slot, with tumbling reels feeding base-game chains, free spins ready to retrigger, and a Fort Knox Bonus that climbs four jackpot tiers all the way to 500x your bet.

On the back of the tumbling mechanic, my base game stayed strong throughout the whole session. Wins came more frequently than strong, and that's my favourite model. Every two to five spins, I'd hit somewhere between 0.8x and 3.6x my bet, and that was more than enough.

I waited a long time to trigger the free spins, but I hoped it would be worth it, and my balance approved the wait.

The free spins kick in when three bonus symbols line up across the first three reels, which puts six spins on the counter. From there, three more bonus symbols anywhere during the round can add 2 to 4 spins, four can add up to 10, and five can stretch the count to 15.

My six spins felt slow until the third one, when three bonus symbols dropped across the grid and added four more. The tumbling reels did the rest. A pair of Mona Lisa lines chained into a Lady with the Ermine hit, the chain kept going for two more tumbles, and by the time the round closed, the counter landed on 52x my bet.

The Fort Knox Bonus is a separate path to the jackpot, with four tiers from Copper at the bottom up to the Platinum top. You collect three matching symbols to win the corresponding tier, and a boost meter can push the prize values higher when it breaches. Mine never showed up.

Overall, the view alone would've been worth the session, and the frequent wins just sealed the deal. The luck started in the base game, and the bonus round just rode the wave from there.
