This is a 5-reel 40-payline game with eight rows of symbols visible at a time. IGT applies its branded Tumbling Reels feature that allows new symbols appear and complete combinations during one single paid spin. Mixing the Da Vinci’s paintings and gemstones, the slot offers sophisticated gameplay with a couple of added features such as wilds, scatters and free spins. Despite the elongated game field, the game runs perfectly on mobile devices. Bet sizes are suitable for conservative gamblers and heavy bettors alike.

The game reviewed below is an improved edition of Da Vinci Diamonds. The latter is IGT’s high-end slot that has a strong following among online casino visitors. Da Vinci Diamonds: Dual Play offers double the fun with double reels. The key innovation brought about in this game is a big game field. Instead of a 5×3 layout, which is normally used by slot manufacturers, IGT put in place the 5×6 format. This means you get double action and more chances to hit a winning combination.

Tumbling Reels feature explained

From their emergence at land-based casinos and online, slots have been using drums (at physical machines) and reels (in online casino games) that rotate vertically and then stop with a new set of symbols on them. This is a conventional approach to slot making, which is found in 99% of today’s slots. IGT designers broke that traditional lockstep and came up with a new model for shuffling the symbols. In slots based on the Tumble Reels feature the reels do not spin – in fact, these are not reels in the traditional sense but columns.

The visible symbols are replaced with a new set in the following way. Clicking the button that starts the round, you make the symbols avalanche downwards and disappear completely. Then new symbols fall down from above and you can see an entirely new arrangement of symbols, with winning combos or without them. The similar format is implemented in some games from NetEnt (not accepting Canadian players).

Winning combos are formed from left to right on active lines. Whenever any symbols create a match that must be awarded in accordance with the paytable, you receive the related cash prize, the involved symbols then vanish and the pictures located above drop down to occupy the free positions. This step may result in new winning combinations, which makes the process continue until no more winnings are recorded. As a result, you obtain numerous winnings that stem from a few consecutive avalanches of symbols.

Non-feature symbols, bet sizes and payouts

Low-valued pics are represented by orange, green and red gems (the max payout is 100 coins for five of the same). High-valued imagery represents three Da Vinci’s paintings and the slot’s logo. The paintings award up to 1000 coins, while the logo pays out 5000 coins for five of a kind – this is slot’s top prize up for grabs.

A bet is adjusted by changing a single option known as a line bet. There are easily recognizable “+” and “-“ buttons that allow for increasing or decreasing a line bet, with the minimum being $1 and the maximum $50. Therefore, the total bet ranges between $40 and $2000 per spin. With this in view, the top payout amounts to an astounding $250,000 if you manage to spin in five logos.

Wild symbol

The wild performs just basic functions in Da Vinci Diamonds: Dual Play. It serves as a substitute for non-feature pics and has no multiplier effect. It cannot create its own combinations. Sure, it is a very helpful symbol because it helps you get a win in case some regular symbols are missing.

Free spins with added paylines

Free spins are the most sought-after mode in any video slot because players receive assets without having to pay for spins. In the reviewed game, the feature is more lucrative and richer than base game because it comes with 20 additional paylines. The base game has 40 constantly active paylines but entering free spins, you have more chances of landing a payable combination of symbols because there are 20 more patterns on which the matching symbols can stop.

To unlock the feature, you need to hit three BONUS pics on any payline left to right. You are then awarded 6 free spins. This amount may seem insufficient for winning some massive prizes but free spins are developed in a way to maximize your wins at no cost. For one thing, free spins are retriggerable. If you land 3 Bonus symbols again, you will be awarded 6 extra free spins. And for another, you get 20 more paylines to land the matching symbols on, aside from the unique Tumbling Reels feature that is potentially lucrative in its own right.

Summary

Da Vinci Diamonds: Dual Play is a big 5×6 slot themed around Da Vinci’s artistic legacy and gems. The slot has a Tumbling Reels feature that creates symbol avalanches with the chance for bigger wins. Besides, you have a wild substitution pic, a scatter and retriggerable free spins played with 20 extra paylines. The max potential win in the game is $250,000.
