This is a 5-reel 20-payline video slot based on the legendary role-playing game that played an important role on the generation of the 70’s and 80’s. Inspired by this fabulous game, IGT commemorated three slots to D&D, including Crystal Caverns. Players who still remember this epic fantasy game will appreciate the efforts exerted by the famous slot vendor. Here you will find a lucrative Tumbling Reels feature, wild symbols and retriggerable free spins with high prizes. The slot is also compatible with mobile devices.

Crystal Caverns of the Dungeons and Dragons line-up takes you to deep caverns where ugly and mighty dragons live. They are safeguarding crystals and other treasures and the task of three heroes presented in the slot is to kill the beasts and collect the crystals. The enticing gameplay is enhanced with a set of themed symbols that create the needed atmosphere of the original board game. As for the slot’s layout, it has a traditional 5×3 format with 20 fixed lines. Winning combos are also created in a conventional manner, from left to right on neighboring reels.

Tumbling Reels format

The slot utilizes the Tumbling Reels model, which is not unique for IGT slots but is a kind of innovative system in the video slot industry. Actually, it can be found in a few games from other providers but it has not obtained a wide circulation as of today.

In any normal 5-reel or classic pokie, there are reels that spin downward and then stop to show the symbols arranged in a new way. The basic idea behind spinning is that video slots imitate a physical rotation of the reels in land-based slot machines. Tumbling Reels behave differently from traditional reels. Imagine a 5×3 layout with 15 visible pictures. On clicking Spin, the visible symbols drop down as if pooled by the force of gravity and disappear from the board. A moment later a new set of 15 symbols falls from above the top edge of the screen and gets arranged in a familiar 5×3 formation. In both models, whether spinning or tumbling down, a paid spin ends with a new set of symbols.

The Tumbling Reels has an enhanced addition to it, and this is what most gamblers adore. When a paytable-defined combination is created as a result of a paid spin, you get an adequate award, the involved symbols disappear and the above-positioned symbols fall down with the chance to create new combos. These avalanches carry on until a subsequent avalanche brings no wins.

Non-feature symbols, bet options and payouts

The reels are set inside a deep grey cavern and the symbols used in the game suit the theme perfectly. Low-valued imagery includes three different crystals with the highest payout being 100 coins for five green crystals. High-valued pics include a blonde archer (x300), a red-haired elf (x500) and a knight (x1000). And the top-paying symbol, which awards x5000 for five of a kind, depicts the D&D logo.

A bet size is regulated by clicking two line bet buttons. The minimum acceptable bet is $0.20, while the maximum bet runs to $1000 per spin. Now you can do some maths and calculate the top three payouts up for grabs; these are $250,000 for five D&D signs, $50,000 for knights and half as much for elves.

Wild symbol

The wild symbol in the game is represented by an intricate dragon-shaped metal amulet with the word “Wild” across it. It acts as a very basic wild symbol, meaning it has one single ability – substitution for non-feature pics. Unfortunately, it has no multipliers attached or other interesting perks. Nonetheless, it can be very helpful at times and will assist you to reap more wins than you can expect.

Scatter and Tumbling Treasures free spins

Free spins are triggered if you make three Bonus symbols stop on reels 1, 2 and 3 on an active payline. Should this occur, you get 6 free spins. This is a quite beneficial game mode because it:

• Incurs no expenses for you
• Has a richer paytable with brand-new symbols
• Runs with three Monster scatters.

In free spins, there are 5 regular symbols depicting jewelry and 3 scatters. Unlike normal pics that pay out when arranged on an active line, scatters (Skeleton, Ogre and Golem) pay in any position. Just get three, four or five of them at any place and you receive x2 to x30 a total bet. If wagering the maximum possible bet, the highest win in free spins reaches $250,000 (five D&D pics). The top potential scatter win is $30,000.

Free spins have a retriggerable design, meaning you can extend the free gameplay if landing 3+ again during the feature. On hitting:

• Three scatters, 2 to 4 spins are added
• Four scatters, 4 to 10 spins are added, and
• Five scatters, up to 15 additional spins are granted to the remaining free spin meter.

Summary

Dungeons and Dragons: Crystal Cavern is a game-based video slot with 5 reels, 20 paylines and the Tumble Reels feature that improves the winning odds. Besides, the slot has a wild symbol and free spins that are played with three valuable scatters. The game is recommended for mobile and desktop users with different budget sizes.
