What the Buy Menu Offers
The buy menu offers four options of two different kinds. Two are modes, priced per spin, that stay switched on until the player turns them off. The other two are one-off purchases at a fixed price, and they drop the player straight into a bonus round. BonusHunt FeatureSpins costs 3x the bet and makes a trigger five times more likely on every spin. Rainbow FeatureSpins costs 50x and guarantees a Rainbow lands. Luck of the Bandit is 100x for the 8-spin bonus, All That Glitters Is Gold 250x for the 12-spin one.

The Four Doors, Read off the BUY BONUS Screen at a Bet of 1.00
| Purchase | Price on screen | What it does | Stated return | Volatility label |
|---|---|---|---|---|
| BonusHunt FeatureSpins | 3.00 a spin | Every spin is five times more likely to trigger a bonus | 96.28% | High |
| Rainbow FeatureSpins | 50.00 a spin | Every spin guarantees a Rainbow symbol lands | 96.36% | Medium |
| Luck of the Bandit | 100.00 | Buys the 8-spin bonus outright | 96.3% | Medium |
| All That Glitters Is Gold | 250.00 | Buys the 12-spin bonus outright | 96.4% | Medium |
Figures current as of ; the operator's live terms prevail.
Each Purchase Has Its Own Return
Each of the four purchases carries its own published return, and the client prints all four in its rules screen, one line per purchase. The buy menu itself shows name, volatility and price; the percentages live one screen away. Read them in order and the numbers sit between 96.28% and 96.4%.
The spread is tiny. Twelve hundredths of a percentage point separate the best card from the worst, and the direction is mildly counter-intuitive, because the most expensive door carries the highest stated return of the four. Those figures belong to the 96.34% build, and a casino running 88.36% ships a different set of cards; the rules screen inside that casino's client is the only place they can be read.
The Door That Does Not Open
The door that does not open is Treasure at the End of the Rainbow.

That is the best round in the game, and the only one with no price on it. Twelve free spins, a guaranteed Rainbow every time, and the Bronze tier pulled out of the pool, so every coin that lands is Silver or better.
We checked the screen rather than trusting the studio's game page, and the page was right: four cards, and the five-scatter round is absent from all of them. The client's own rules say nothing either way about buying it. A player who wants it has to land five scatters in the base game, at a frequency the maker withholds.
Buying Under a British Stake Cap
A British £5 cap does not make the purchases smaller: the price is a multiple of the bet, so at a £5 spin the 250x door costs £1,250 in one click. The client states its own stake range, 0.10 to 100.00, and adds one line about that range: feature buys can exceed it. A regulator's cap is a different thing, and the maker cannot lift it.
What One Click Costs Once the Spin Is Capped at £5
| Purchase | Price in bets | At a bet of 1.00 | At a £5 spin |
|---|---|---|---|
| BonusHunt FeatureSpins | 3x | 3.00 | £15 a spin |
| Rainbow FeatureSpins | 50x | 50.00 | £250 a spin |
| Luck of the Bandit | 100x | 100.00 | £500 |
| All That Glitters Is Gold | 250x | 250.00 | £1,250 |
One thing this page cannot tell you is where that menu is on offer: we read it in the maker's own demo, and we have not checked a single British licensee for this game. We do not recommend the 250x purchase at a capped stake. A player who accepted a £5 ceiling on a spin is accepting a £1,250 ceiling on a click. The published return on that click is 96.4%, not something higher.
