Hold and Spin
Land 3 or more bonus symbols to trigger the Megaways Hold and Spin feature. A new 10x10 grid will appear, with the normal reels replaced by ones that contain just rocks and empty spaces. Thoe rocks have fixed values as follows:
- Blue Rock – 0.1x
- Green Rock – 0.2x
- Golden Rock – 0.4x
- Pink Rock – 0.6x
- Red Rock – 1x
Depending on how many bonus symbols trigger the feature, this will determine whether the lowest paying rock symbols are present or not.
- 5 bonus symbols = only the orange, pink, and golden rocks are present
- 4 bonus symbols = only the orange, pink, golden, and green rocks are present
- 3 bonus symbols = all rocks are present
All rocks that land will stay in place until the end of the feature. Additionally, any that land will reset the respins to the original 3 that you get to begin with.
If you get a 2×2 or a 3×3 cluster of the same rock symbol, it will transform into a big rock and be given a random multiplier.
- 2×2 cluster = between 5x and 10x multiplier
- 3×3 cluster = between 35x and 500x multiplier
After each respin, there’s a chance for rock symbols to be randomly added to the screen with a fire animation.
To the left of the 10×10 grid, you’ll see a key collection mini-game. Rock symbols can land with a key symbol on them. These are then added to the collection. You can be awarded one of the following once you reach a chest:
- A random rock symbol will be multiplied by between 0.5x and 500x
- A random direct money awarded from 10x to 500x
- Receive between 4 and 10 keys randomly to add to the trail
- A multiplier between 2x and 100x will apply to the total win of the round
- A bonus feature retrigger
If you manage to reach the Mystery Multiplier at the end of the trail between 2x and 100x is collected and multiplies the general multiplier you’ve got so far.
What’s great about this feature is that it can be retriggered from either a chest or by filling the whole grid with rock symbols.
