Slots with an Irish Luck theme appeal to a huge number of players, and they often star happy leprechaun characters, while filling their reels with rainbows and four-leaf clovers. Fans of this style will be delighted to see that the Emerald King Rainbow Road slots game has all of this and more across the 5 reels and 20 lines.
Brightly coloured playing card symbols also appear, and while it’s a fairly retro-style game, the graphics look good on PCs, as well as mobiles using the iOS, Android, and Windows operating systems on any of our top-ranked online casinos.
Look out for green-tinted reels in any spin, as these unlock mini slot machines which spin for as long as winning combinations appear on them. A prize-picking round is worth up to 200x your stake, but it’s at the end of the bonus trail where the massive 20,000x bet multiplier is found.
This game is co-developed by Reel Kingdom and Pragmatic Play. It uses a straightforward set of controls to make it easy to set up, including at the best mobile casinos, and offers a wide choice of stakes to suit players at almost any budget. You can play for between 0.20 and 240.00 per spin and have options such as automatic spins and fast-play modes.
The ‘I’ tab opens up a paytable, and it’s here that you see how much each symbol pays out at your chosen bet level. The game logo is the most valuable, worth 5x, 15x, and 25x the stake when landing on 3, 4, or all 5 reels across a payline.
Any 3, 4, or 5 pots of gold trigger a Pick Me bonus. You click the pots to reveal either win multipliers, or entry to the Rainbow Road feature, but the potential wins depend on how many pot symbols launched the round. Three pots can reveal prizes of up to 20x the bet, while 4 can be worth up to 40x and you can win a maximum of 200x when 5 pots of gold land on the triggering spin.
Random reels can become tinged with an emerald green colour at any time. Up to 5 mini 3-reel slots games then appear with a single payline crossing each one. These spin blue, yellow, or red 7 symbols, or blank spaces, paying prizes of 1x your bet for any colour mix, or 5x, 10x, and 15x for matched colours. The reels keep spinning on wins, but vanish on losing spins until none are left and the feature ends.
Any 3 or more images of the happy leprechaun will take you through to the Rainbow Road bonus round, where you follow the Emerald King along a bonus trail with 22 points. At each point, you could collect a bonus, or trigger the mini-slots to move along the trail, but look out for ‘Collect’ symbols, as these end the feature and pay out any prizes picked up so far.
If you get to the end, a Big Money slot spins up a win of between 50x and that vast 20,000x your bet.
Claim the 20,000x win multiplier at the maximum stakes and you get paid 4,800,000.00. The average return to players percentage of the Emerald King Rainbow Road slot is 96.71%, which is excellent, but it makes you work for your wins, as it comes with a high volatility.
This Celtic-themed game brings lots of colour to PCs and mobiles. A few more themed symbols and fewer playing card icons would perhaps improve the looks even more, but it’s not a real issue.
The multiple bonus features bring plenty of excitement to the gameplay, and each leads to a guaranteed win, even if it’s via entry to the Rainbow Road in the Pick Me round. Landing a massive win of 20,000x your stake won’t be easy, but play the Emerald King Rainbow Road slot at our recommended online casino sites and who knows, maybe the famous Luck of the Irish will be on your side.
