Before we even get to the BB, aka the Big Bet, you have two other ways to approach this real cash slot, either via the <2.00 or >=2.00 options. This sounds very technical, but in fact it simply refers to the amount of cash you put down; if you play with 2 credits or over you’ll get higher wins, but play with lower than that and the pay outs will change accordingly. This explains why there’s so many versions of the pay table to play through.
For example, when you play with a stake of under 2 coins, the top amount you can win is x10 of your bet for either the wild symbol or the royal blue gem. However, if you play without the above limit, the top amount is x20.
Consequently, the more money you can play with the better your odds of scoring big, which is going to be sad news for those of you that like small pay-ins. That being said, the lowest you can wager is just 0.10, which isn’t half bad.
There’s a purple widget next to the regular spin button that will take you to three different Big Bet options. A shower of dust and blue curtains will close on the normal grid and open up on a new one, essentially symbolizing that the game and its rules have changed.
Players can play with either a bet of 20, 30 or 50 credits, with the latter being the highest possible stake in this section. Each level has it’s own benefits, such as the Crowning Glory Feature, which we’ll get to soon enough. The (+) and (-) will help you change between the options, with the select button on each triggering the associated round.
A total of five waves is all that’s given to you, and during that time you must try and get a further 8 or 16 games, only they’re now free. Should you not manage that, you simply walk away with whatever winnings you’ve earned thus far.
Crowning Glory is your pathway to the free games in the BB rounds, as we mentioned previously, and to put it into action you need a shining red crown to appear.
There’s six spots to fill upon the line-up presented just below the title, with the crowns becoming illuminated whenever you find a matching symbol. Five of them get you the 8 games, while the sixth enters you into the 16 rounds. During our play through we only managed to get a maximum of four crowns of Crowning Glory before our time was through, which is good going considering there’s only five chances.
The volatility is very high here, meaning that you’re likely to risk a lot of cash for minimal returns. That being said, when your chance pays off, it does so in abundance.
Jewel in the Crown is by far the most innovative and thrilling slot machine we’ve come across in some time, and all without an overzealous aesthetic. It uses clever tactics and design features to create a game that has many dimensions to it, thus ensuring you never tire too easily of the action. Barcrest got it so right with this slot.
