Dungeons and Dragons Crystal Caverns features Tumbling Reels®. Reel symbols fall from the top of the screen instead of spinning. Winning symbol combinations disappear and new symbols tumble down to replace the vanished symbols. You can win again and again and again on the same play of the reels!

The WILD icon can substitute the icons below to help complete a winning line:

Rules

Malfunction voids all pays and plays.

All line pay symbols must appear on a played line and on consecutive reels, beginning with the far left reel.

All payline wins occur on bet lines only.

Only highest winner paid on each payline.

Only one award paid per payline.

Line wins are multiplied by the total number of credits bet on the winning line.

Coinciding wins on different paylines are added. Scatter awards are independent from payline awards and are also added to the total amount paid.

Awards are shown in credits

The maximum award on any transaction is capped at 250,000 currency units (pounds, for example). A transaction includes the results of free spins in bonus plus the outcome which launched the bonus.

Tumbling Reels® Feature
All paytable-defined symbol combinations trigger the Tumbling Reels® feature during regular and Tumbling Treasures Bonus game play. All winning symbol combinations are evaluated and values are added to the credit meter.

All symbols in winning combinations disappear. All symbol positions on each reel are filled as symbols tumble from above, in sequence, to fill all empty spaces. The game screen is re-evaluated for symbols in winning combinations and values are added to the credit meter.

The Tumbling Reels® feature remains active until no winning symbol combinations are created as a result of the reels tumbling.

Tumbling Treasures Bonus
Bonus symbols appear on reels 1,2 and 3 only and the bonus round is triggered when three bonus symbols appear on Reels 1, 2 and 3 of a played line.

You can trigger the Tumbling Treasures Bonus by getting three Bonus symbols on a payline. Upon triggering the Bonus, you receive 6 free spins.

During the Tumbling Treasures Bonus, you can retrigger the Bonus multiple times. Your Tumbling Treasures Bonus continues until you have 0 spins remaining, or until you have played 300 free spins. To retrigger the Bonus, you need to get 3, 4 or 5 Bonus symbols anywhere on the Bonus reels. If you get 3 Bonus symbols, you have an equal chance to win an additional 2, 3 or 4 free spins. If you get 4 Bonus symbols, you have an equal chance to win an additional 4, 6, 8 or 10 free spins. If you get 5 Bonus symbols, you have an equal chance to win an additional 6, 8, 10, 12 or 15 free spins.

During the Tumbling Treasures Bonus, your bet per line in the bonus is equal to the bet per line on the reel spin that triggered the Bonus. In the Tumbling Treasures Bonus, the reels are much richer and there are more ways to win. With the Monster Scatter feature, you only need to get 3 or more of the same monster symbol anywhere on the reels to win! See the paytable for details.
