Inside the game
How 3 Jewel Crowns works
Three Crowns change the Free Spins setup
Three Crowns change the Free Spins setup
Each activated metre contributes a different feature. The useful question at entry is which of EXTRA SPINS, JACKPOT and DOUBLE REELS is enabled, rather than simply whether a bonus has started. All three can be active together.
Wild multipliers help ordinary combinations
Wild symbols substitute for missing symbols in winning combinations and can carry a 2× or 5× multiplier. Their role belongs to the formation and value of a winning combination.
A Wild multiplier should not be confused with a jackpot amount or an instruction to multiply every visible prize. The documented values identify enhanced Wilds, while the separate Crown features determine the Free Spins configuration.
EXTRA SPINS and DOUBLE REELS do different jobs
EXTRA SPINS adds seven Free Spins to the feature. It changes the allowance of spins, whereas DOUBLE REELS activates a second game board.
Those two improvements can coexist. More spins change how long the feature can run; another board changes what is played during that allowance. Neither means that the jackpot feature has also been enabled unless its Crown is active.
Follow the feature indicators and remaining-spin display separately. A second board is not, by itself, another seven spins, and an extra-spin award is not a promise that either board will produce a winning combination.
Jackpot values grow within stated caps
Whenever a Crown lands, it increases a randomly selected jackpot by an amount equal to the current bet, up to a set cap. Minor can grow from 25× to 50× the bet, Major from 100× to 250×, and Grand from 1,000× to 5,000×.
The displayed amount therefore has a history within the game's rules. It is not a permanently fixed number at the starting value, nor an unlimited progressive prize that can rise indefinitely.
The source does not specify how every change of stake or session affects that display. Check the active game's rules before assuming a previously seen monetary amount carries unchanged into a different configuration.
JACKPOT mode controls eligibility
Minor, Major and Grand are exclusively available during Free Spins with the JACKPOT feature active. Their values may grow as Crowns appear, but growth and eligibility are separate conditions.
This distinction prevents a common misreading of the interface: a large Grand number above the base reels is not evidence that any ordinary base spin can collect it. The feature indicator matters as much as the displayed value.
The retained material does not provide a universal stake range or exact RTP variant. Evaluate the current total stake and the enabled Crown combination without treating a maximum jackpot value as an expected result.

04 / The SlotsCollector take
Verdict
3 Jewel Crowns is most distinctive in the relationship between prize growth and prize eligibility. A Crown can improve a displayed jackpot, while a particular Free Spins feature is still required to make that jackpot available.
The three features also have clear separate roles: duration, a second board and jackpot access. Reading those roles together gives a more useful picture of the bonus than focusing only on the largest number above the reels.
