Rainbow Burst slot REVIEW

Rainbow Burst ReviewWe have exactly 485 slots featuring Leprechauns in our catalog at the time of writing, and Nailed It! Games adds another one to the pile with Rainbow Burst. We have to say that we got a little bit spooked by the look of this little guy, but his fairy counterpart is all charm when she appears. The 5x3 grid is placed on a green hill with a tree and an almost circular rainbow in the background, and you get a bunch of celtic symbols spinning on the grid.

There is nothing too extraordinary about the visual presentation in other words, and the game is all about collecting cash prizes in different ways. Cash symbols up to 1,000x can be collected, and they land in stacks. A full-reel stack triggers a respin feature which can increase your winnings, and the stacks keep growing per free spin. Rainbow Burst also rewards loyal players with a collect system that eventually triggers a guaranteed prize up to 5,000x your stake.

Nailed It! Games - Slot Developer

Nailed It! Games is a budding developer with ambitions of disrupting the online slots market by delivering innovative and high-quality products. Based in Poland, the small team has released 8 video slots since their late 2022 debut called Gold Mine Stacks. Whether or not they manage to live up to their lofty ambitions remains to be seen, but we have enjoyed most of their games so far at least.

Slot Theme And Storyline

It’s safe to say that the Irish Luck Leprechaun theme is an evergreen trope in the world of online slots, but this also means that avoiding cliches can be a challenge. Rainbow Burst doesn’t really stick out all that much in that regard, except for the fact that the Leprechaun looks a bit evil and scary. This is probably not intentional, and his female counterpart looks nice and harmless enough to balance things out. The celtic symbols are nicely done, but also a tad generic.

Rainbow Burst RTP, Volatility, And Max Win

The top-tier Rainbow Burst RTP of 96.15 % is a little bit above average. However, operators can adjust the RTP down to 94.15, 92.15, or 86.9 %, depending on the market. This is a medium volatility installment from Nailed It! Games, which makes it suitable for most player types. The Rainbow Burst max win is 5,000x your stake, which is not uncommon for this volatility level according to our numbers.

Rainbow Burst Rules And Gameplay

You win by landing 3 to 5 matching symbols on up to 10 paylines starting from the leftmost reel, and the top-tier Beer Mug symbol also pays for 2 of a kind wins. Rainbow Burst slot comes with a hit rate of 28.07 %, which means that almost every 3rd spin is a winner on average. You can adjust the bet levels between £0.2 and £40, which is a decent range that may not quite satisfy hardcore highrollers.

Rainbow Burst Bonuses And Special Features

Rainbow Burst revolves around the money symbols collection feature, but you also get a respins feature that can increase the money stacks you collect. In addition, loyalty is rewarded by eventually triggering the Rainbow Burst jackpot feature.

Rainbow Symbols

You get stacked Rainbow Symbols (they look like gold coins to be clear) on the 3 middle reels, and they come with cash prizes of 1x, 2x, 3x, 5x, 10x, 50x, or 1,000x the stake. The 3 top-tier prizes are known as the Mini, Midi, and Max prizes, and rainbow symbols land in stacks of 3 symbols during main game play (but not always fully in view). You need the Collect symbol on reel 5 at the same time, however, otherwise the prizes are not collected.

Rainbow Respin

You get a Rainbow Respin when at least one stack of rainbow symbols land fully in view, and the remaining reels will then spin again. This can land you more rainbow stacks, the Collect symbol, and/or line wins. Any rainbow symbols not collected on the initial spin is collected in the Leprechaun's Pot seen below the grid, and landing a Collect symbol (female Leprechaun) on the respin also collects this pot. Landing a new full-reel of rainbow symbols awards another respin.

Rainbow Burst Free Spins

You need a free spins bonus symbol on reel 1, as well as the Collect symbol on reel 5, to trigger the Bonus Round in Rainbow Burst slot. This gives you 8, 12, or 16 free spins, and the number will be displayed on the triggering free spins symbol. You can retrigger the feature the same way, which awards 4, 8, 12, or 16 new free spins. The Rainbow stacks grow by +1 per free spin for the duration of the feature.

Bonus Buy (not UK)

We didn’t find any bonus buy feature in Rainbow Burst, or at least not in the demo game we had available at the time.

Rainbow Chests

Full stacks of Rainbow symbols are added as a rainbow to either the Iron Rainbow Chest (base game) or the Golden Super Rainbow Chest (bonus round). These chests are found below the grid, and each rainbow collection has a chance of triggering the Rainbow Burst feature. The triggering chance increases per collected rainbow, as indicated by the respective chest meters and the animated shaking of the chest.

Rainbow Burst

When the Rainbow Burst feature triggers, you will take down either the Mini, Midi, or Max Rainbow Prize. The 3 jackpot prizes are represented on the merging of reels 2, 3, and 4, and whichever prize appears in view as the merged reels stop will be yours. Reel 1 can boost the prize by a multiplier of x2 or x4 (base game), or x2, x3, or x5 (bonus round).

Review Summary And Verdict

We have enjoyed most of what we’ve seen so far from Nailed It! Games, but they’ve chosen a company name that will be difficult to live up to every time. Rainbow Burst didn’t quite hit the spot for us, and the Leprechaun looks more cunningly evil than charming to be honest. The money collect and respin system provides decent entertainment if you’re into this sort of thing, and you get more of the same in the bonus round.

The growing stacks increases the likelihood of triggering the respins feature during the bonus round, of course, and cracking the 5,000x potential is most likely done via the x5 Rainbow Burst multiplier you may get during free spins. All in all, Rainbow Burst didn’t really engage us too much when we played, but at least loyalty is rewarded on a somewhat regular basis. Players who love the Irish Luck theme might see it differently, and we still look forward to more from this developer for sure.
