Atlantis Crush slot comes with 7 bonus features. With regular cascades, winning symbols activate Block symbols which award free spins, increase the win multiplier up to 500x and add the same kind of symbol onto the bottom grid. These all combine in the 2 free spins features with the win multiplier only increasing for wins of up to 10,000 times bet.
Cascades
As is the case with most Scatter Pays slots, every winning combination triggers the Cascades feature. Winning symbols are destroyed with the symbols present on the grid falling down to occupy the vacated positions. Then new symbols cascade/drop in from above to fill all spaces. If you land another win, the process repeats itself. This continues until no more new wins are created.
Block Symbols
In the top 2 rows of the grid, Block symbols will appear. These are activated by having a winning paying symbol under itself or by the effect of another activated Block symbol. The special symbols that can land include:
- Empty Block: This has no effect.
- Horizontal Destroyer: Activates and destroys all symbols in its row.
- Vertical Destroyer: Activates and destroys all symbols in its column.
- Diagonal Destroyer: Activates and destroys its corner symbols.
- Bonus Block: The Free Spin counter increases by the number displayed on the Bonus Block.
- Multiplier Block: Increases the win multiplier by the number displayed on the Multiplier Block. Values range from 2x up to 500x and applies to wins from the current spin/cascade.
- Fire Gem Block: All red, fire-class symbols on the grid are destroyed and only the same kind of symbols drop in the following cascade.
- Water Gem Block: All blue, water-class symbols on the grid are destroyed with only the same kind of symbols drop in the following cascade.
- Plant Gem Block: All green plant-class symbols on the grid are destroyed with only the same kind of symbols drop in the following cascade.
Destroy All Paying Symbols
If all paying symbols are destroyed in the same cascade, The Destroy All Paying Symbols feature is triggered. In the following cascade, all paying symbols will be of the same kind (i.e. red, green or blue).
Destroy All Blocks
The Destroy All Blocks feature is activated when all Block symbols are destroyed in the same cascade. For the rest of that spin and subsequent cascades, only Multiplier, Bonus and Gem Blocks will appear.
Free Spins
The Atlantis Crush slot game comes with a Free Spins feature. It’s triggered when 3 or more Bonus Blocks land. If you take the sum of all numbers of the triggering Bonus Blocks, that will be your free spins tally.
More importantly, the base game’s win multiplier is transferred over and will not reset during the feature. When Bonus Blocks are activated, their value will increase the free spins tally.
Super Free Spins
When you trigger the Free Spins feature, there is a chance the Super Free Spins feature will be triggered instead. With the free spins tally calculated in the same way, only Multiplier, Bonus and Gem Blocks will land in the Blocks area.
Bonus Buy
For players outside the UK, there is a Buy feature which is optional. With 2 options to choose from, you can buy your way directly into the free spins or super free spins with the RTP rate also changing. Below are the details:
