Mystery Symbol Mechanic
The Full Mystery symbol is designed to cover an entire reel from the top to the bottom. Every slot covered by the Full Mystery symbol converts into either a random paying symbol or the Money symbol. Symbols revealed through the Full Mystery symbol award according to the paytable, irrespective of adjacencies. If Money symbols are unveiled and a sufficient number appear on the reels, this activates the Respin feature.
Respin Feature Details
The Money symbol reveals a random prize from a predetermined range when it appears. In the base game, possible values are: 1x, 2x, 3x, 5x, 10x, 15x, 20x, 30x, 50x, 75x, 100x, 200x, 300x, 400x, 500x, or 5000x the total bet, as well as the possibility to unlock Free Spins or Super Free Spins.
When six or more Money symbols land anywhere on the reels, the Respin feature begins. Non-Money symbols fade and only Money symbols remain visible. The reels then respin, and only Money symbols or blank spaces may appear. New Money symbols stick to their positions for the duration of the feature. The feature starts with three respins; each new Money symbol resets the respin counter to three. The round ends when no respins remain or the grid is completely filled with Money symbols.
After the Respin round, all values displayed by Money symbols are summed and paid. Should all positions be filled with Money symbols, an extra 2000x total bet is awarded. If any Money symbol has values for Free Spins or Super Free Spins, the corresponding round is triggered at the end of this feature.
Free Spins and Level Progression
Three Scatter symbols trigger the Free Spins round. Before Free Spins begin, one regular or Money symbol is randomly picked as the Mystery symbol active for the session.
If two Scatter symbols and one Super Scatter appear, the Super Level Free Spins feature is triggered, where the Mystery symbol is always the Money symbol.
- A, K, Q, J as Mystery symbol: Bronze level
- Scroll, Ink Bottle, Telescope as Mystery symbol: Silver level
- Globe or Hourglass as Mystery symbol: Gold level
- Money symbol as Mystery symbol: Super level
Before Free Spins start, the player may choose to gamble and attempt to improve the Mystery symbol or level, or to collect and proceed. When gambling, a book will spin and land on a symbol, level, or blank spot. Landing on a new symbol or level advances the round, while landing on a blank ends the round immediately. The probability of success in each gamble depends on the current Mystery symbol and round level. This option is available until the Super level or Money symbol is reached as the Mystery symbol.
Once the Mystery symbol or level is collected or the top tier is reached, Free Spins commence. During these spins, any Full Mystery symbols nudge to fill an entire reel and reveal the selected Mystery symbol.
In Super level Free Spins, achieving enough Money symbols via the Full Mystery symbol instantly activates the Respin feature.
Scatter symbols collected during Free Spins are added to a meter. Every four collected in Bronze, Silver, or Gold level upgrades the round to the next level, randomly chooses a new Mystery symbol, and awards two more Free Spins. When playing at Super level, two extra Free Spins are given each time four additional Scatters are collected. Special reels are in play during these features.
Maximum Win
The potential maximum win in John Hunter and Galileo’s Secrets is 5,000x the current total bet. Once this amount is achieved during a round, the round will end, and all remaining features are forfeited.
