Play Royal Jewels for Free

Casino Technology is one of a new breed of East European software giants forging a path on the world stage. The Bulgarian-based developer is rivaling Cayetano for the sheer scale of its output. You will find over 100 Casino Technology online slots to play for real money right now. The range of slots in its arsenal includes classic themes like ancient Egypt and jungles, but Royal Jewels is the Sofia developer's take on the gem theme.

Royal Jewels is categorized under Casino Technology's 'Smart' range of slots (it also has 'easy', 'soft', 'smooth', and 'hard' slots available). This, the developer says, is to "get your heart beat [sic] faster" and "win the long-waited reward!" You can enjoy the free Royal Jewels slot machine online at most Casino Technology-powered sites. The slot is played on five reels and three rows, and there are 10 paylines to bet on. Coins start at just 0.01, but it's possible to set the stakes as high as 0.50 per coin.

The gamble feature is a solid if unspectacular bonus of Royal Jewels. After any winning spin worth less than 10x the player's total bet, there is a chance to double it up. The feature runs like a classic red/black guessing game where you must guess the color of the next card drawn. Do that, and you will double your win. Alternatively, you can try and guess the next suit drawn to earn 4x your total win.

Precious stones form the majority of the icons in Royal Jewels and even the low-limit symbols can pay well. The yellow and purple gems pay from 10x to 100x your line bet for three to five of a kind, while the blue and orange gems pay 10x to 150x. The emerald and cut diamond fare a little better, paying a top prize worth 200x your line bet.

There are two high-limit symbols to look for in the game. The red heart-shaped ruby pays 50x to 500x for three to five of a kind, but the red 7 is the jackpot icon. This pays the player a best jackpot worth 1000x. Winning combinations of five symbols pay both left to right and right to left. This is a fairly standard feature of Casino Technology slots.

If you've played other Casino Technology slots in this range, you will know that the wild symbol takes center stage. The crown symbol acts wild in this slot and substitutes for all other symbols in the game. If one or two wilds appear on a single reel, they will expand to fill the whole reel. Wilds only appear on reels 2, 3 and 4.

If you love the reel respins feature in your slots, there is plenty of choice out there. But Casino Technology seems to be particularly adept at using the feature. In Royal Jewels, if a wild appears on one of the central reels, it will expand and remain in position. The whole reel will hold and the remaining reels will respin for one spin. If a further wild appears, it will also stick on the reels and the player gets a further reel respin.

If Royal Jewels is your first experience of a reel respin slot with a sticky wild feature, you may be pleased to know that Casino Technology has other similar games in its portfolio. Chilli Fruits offers almost identical payouts to this game, with a 1,000x line bet jackpot available to gamblers. Many of the hot, hot symbols in that slot appear stacked too. This can certainly increase the variance, but it makes for some big wins when the symbols manage to align.

Monkey Sevens is another Casino Technology online slot with sticky wilds that appear on reels 2, 3 and 4. The reel respin feature works a little differently in this game. Players get two, four or six free spins depending on how many sticky wilds they landed in order to trigger the feature. Monkey Sevens also includes a Red/Black bonus game feature after any winning spin.

Casino Technology's reel respin slots tend to follow a strict template. But if you want to try another developer, give Betsoft a go. The developer's 3D Kawaii Kitty slot also has 10 paylines, plus expanding wilds on the central three reels.

Royal Jewels can safely be filed under 'volatile slots'. While there are lots of stacked symbols in play, we found we went quite a few spins before lining up any sort of meaningful win. The wilds are abundant, however, and can add a lot of generous prizes to your bankroll. For fans of low-limit slots, there's a great choice available. Royal Jewels allows punters of all wallets the chance to win some real cash. Give it a play for free and see if you can improve your jewel haul.
