Review: Da Vinci Diamonds Wild Bonanza – A Classic Look with a Brutal Math Model
IGT has taken one of its most nostalgic titles – the classic Da Vinci Diamonds – and pasted it onto the popular 6×5 scatter-pays grid. If you’ve played Sweet Bonanza, you already know the drill: land eight matching symbols anywhere on the screen, watch them pop, and hope the tumbles bring down more winners.
It’s a familiar, fun setup, but there’s a catch: the math underneath is pretty rough. While similar games (like BGaming’s Bonanza Billion) hover around a generous 96.5% to 97% Return to Player (RTP), this one sits at a punishing 94.02%. You’ll feel it in the base game, too. The paytable is incredibly tight; even the top-tier opal symbol only pays 10x your bet for a cluster of eight, and the lowest gems pay out a measly quarter of your stake.
The Tease: Chain Meters and Dead Multipliers
To break up the dry spells, IGT threw in a couple of base game features, but they can be a mixed bag.
First, there’s the Chain Meter above the reels. If you hit six consecutive tumbles on a single spin, you trigger the bonus without needing scatter symbols. The problem? It resets at the end of the spin. Getting four or five tumbles only to watch the meter wipe clean right before the finish line is agonizingly frustrating.
Then there’s the “Boost” feature, which drops a random multiplier between 2x and 20x onto the board. When it works, it’s great – a decent string of tumbles paired with a 10x multiplier can easily net you a 30x+ payout, which is basically what keeps your balance afloat in the base game. But it cuts both ways. The multiplier only applies to what you actually win on that spin, so watching a massive multiplier drop onto a totally dead board feels like a slap in the face.
Should You Pay for Better Odds?
If you get impatient, you have two options to speed up the action, but only one actually makes sense.
There’s an ante-bet option (the Da Vinci Bet) that costs 25% extra per spin to give you a better chance of landing bonus scatters. Honestly? Skip it. It barely nudges the RTP up to 94.04%, making it a pretty terrible trade.
The 75x Bonus Buy is the better route. Strangely enough, buying the bonus outright gives you a higher RTP (94.46%) than grinding the base game. You get 8 free spins, and every single spin is guaranteed to drop between one and three multipliers (ranging from 2x up to 100x).
But brace yourself, because the bonus is wildly volatile. You can easily buy in for 75x and walk away with a huge loss if those big multipliers land on empty tumbles. A 70x multiplier is totally useless if you don’t connect any symbols. On the flip side, if a 50x multiplier happens to land alongside a solid chain of tumbles, you can easily coast into a 100x+ profit.
The Verdict
Da Vinci Diamonds Wild Bonanza is a solid version of the scatter-pays format, but the underlying numbers really drag it down. The whole game relies heavily on that rare, perfect moment where a massive multiplier lines up with a long chain of tumbles – and honestly, the 8 free spins you get in the bonus usually aren’t enough to make that happen.
When the smartest way to play a game is to completely ignore the base game and just buy the bonus feature, it tells you the math model is asking a bit too much of the player. Play it for the nostalgia, but watch your bankroll.
