Game Rules
The Wild symbol can land on reels 2–5.
Wild symbols substitute for all paying symbols.
Treasure Map Scatter Symbols
“Treasure Map” scatter symbols can land on all reels. They accumulate in both the “Treasure Map” meter and the Gemstone meter.
Once 4 or more scatter symbols are collected in the “Treasure Map” meter, the corresponding feature is activated. After being unlocked, each feature can trigger randomly.
“Treasure Map” scatter symbols land with displayed multiplier values.
Possible values:
- Green: 1x – 10x
- Blue: 15x – 25x
- Red: 50x – 250x
- Purple: 500x – 1000x
These values accumulate in the Gemstone meter and are paid out only during the Mystery Pick bonus game.
Filling the Gemstone meter triggers the Mystery Pick bonus game.
Gem Meter
The Gem Meter collects Scatter symbol multiplier values in the form of treasure maps.
When the meter is fully charged, the Mystery Pick bonus game is triggered. Once the Mystery Pick bonus game concludes, the meter can be filled again.
Meter progress is saved separately for each bet level.
When the bet is changed, the displayed progress will correspond to the current bet.
Treasure Map Meter
The Treasure Map Meter collects Scatter symbols; a new feature is unlocked for every 4 symbols collected.
Multiple features can trigger during a single spin.
Features always activate in the following order: Payway Maker, Symbol Upgrade, Add Wild Multipliers, and Split Symbols.
Once all features are unlocked and the Mystery Pick bonus has been played, the Treasure Map Meter resets, though the features themselves remain available.
Changing the bet size completely resets the Treasure Map Meter.
The RTP contribution from the Treasure Map Meter features is 15.42%.
Payway Maker Feature
The Payway Maker feature is activated upon collecting four Scatter symbols (depicted as a treasure map).
A symbol is randomly selected from the first reel and copied to the other reels, forming a winning combination.
All applicable winnings are paid out, and the feature concludes. Once unlocked, this feature may trigger randomly on any subsequent spin.
The upgrade feature is activated upon collecting 8 Scatter symbols (depicted as a treasure map).
A random paying symbol is replaced by the highest-paying symbol. All applicable winnings are paid out, and the feature then concludes.
Once activated, this feature may trigger randomly on any subsequent spin.
- Add Wild Multipliers Feature
The Wild Multipliers feature is activated after collecting 12 Treasure Map Scatter symbols.
Possible Wild multiplier values are 1, 2, 3, 4, and 5.
Between 1 and 3 Wild symbols with multipliers are randomly added to the reels. Any resulting wins are paid out, and the feature then ends.
Once unlocked, this feature may trigger randomly on any subsequent spin.
The Split Symbols feature is activated after collecting 16 Scatter symbols (depicted as treasure maps).
During this feature, between 1 and 10 symbols of various types are randomly split; the action concludes after the payout is awarded.
Once unlocked, the feature may trigger randomly during any subsequent spin.
The Mystery Pick bonus game is triggered once 20 gems have been collected on the gem collection meter (located to the right of the reels).
The 20 gems collected during the base game carry over to the Mystery Pick bonus game, where the player selects gears until revealing one marked “Collect.” Revealing this gear ends the bonus game.
The player receives a payout equal to the sum of the multipliers multiplied by the bet amount.
The RTP for the Mystery Pick bonus feature is 17.35%.
