Double Rainbow

Double Rainbow Slot Overview

RTP, Volatility & Math Model

Double Rainbow has a 96.38% RTP. That max win figure is solid, though it's a step down from the six-figure multipliers Hacksaw is famous for in games like Wanted Dead or a Wild. The medium volatility tag is the real story here. It means you should see wins landing with more regularity, and the bonus features should trigger more often than in their high-volatility counterparts. This math model is for players who want action without the extended periods of dead spins.

Game Features & Mechanics

Double Rainbow plays on a 7x7 grid using a cluster pays system. You need at least 5 matching symbols touching horizontally or vertically to form a winning cluster. The core of the game is the Double Rainbow Multiplier feature. Every winning cluster you create adds a +1 to a global multiplier that applies to the very next win. This multiplier resets after it's been used, but the key is that wins can chain. If a winning cluster causes cascades, the multiplier applies to each subsequent win in that chain, increasing by +1 each time. A single cascade can see the multiplier climb rapidly from 2x to 3x, 4x, and beyond, significantly boosting a single spin's payout.

The game features two special symbols. The Rainbow Wild substitutes for any regular symbol to help form clusters. More importantly, the Free Spins Scatter symbol triggers the bonus round. Landing 3 or more of these scatters anywhere on the grid grants you 10 free spins. During the free spins, the multiplier mechanic gets a major upgrade. The starting multiplier begins at x2 instead of x1, and, crucially, the multiplier does NOT reset between spins. It only resets when the free spins round ends. This allows for massive growth over the course of the bonus, and it's where you'll see the multiplier climb to the heights needed for those big 5,000x wins.

There's also a bonus buy option, common with Hacksaw slots, allowing you to purchase direct entry into the free spins round. The cost is typically a multiple of your bet, but the exact price isn't advertised on the base game screen.

Visual Design & Theme

This slot is unapologetically bright and cartoonish. The symbols are simple, colorful gems and fruit slices, set against a soft, cloudy sky background. When you hit a win, the game throws a burst of rainbow colors across the screen. The sound effects are cheerful and chimey, with satisfying "clinks" for cluster wins and a rising musical scale when the multiplier increases. It's not a graphically intense or narrative-driven experience. The theme is purely functional: rainbows represent multipliers, and the visuals are there to support the cheerful, fast-paced gameplay. Some might find it a bit basic compared to more cinematic slots, but it's clean, runs smoothly, and doesn't distract from the core mechanic.

Who Should Play Double Rainbow?

Double Rainbow is a perfect pick for two types of players. First, it's great for casual players or those new to cluster-pay slots who want frequent engagement. The medium volatility and cascading wins with multipliers create a steady stream of smaller hits that keep the balance moving. Second, it's an excellent choice for seasoned Hacksaw fans who need a palate cleanser. If you've been burned by the brutal variance of "Wanted Dead or a Wild" or "Stack 'Em," this game offers the studio's signature crisp gameplay and multiplier focus in a much more forgiving package.

You should probably skip Double Rainbow if you're a hardcore high-volatility grinder who lives for the one-in-a-million spin. The 5,000x cap, while impressive for a medium-volatility game, is lower than what you'll find elsewhere. Also, if you need deep thematic immersion or complex bonus mini-games, the simple rainbow-and-gems aesthetic and single free spins mode might feel too lightweight. This is a mechanic-first slot, and its appeal lives or dies on whether you enjoy watching that multiplier tick upward.

Looking for a colorful and fun double rainbow slot that feels a bit more balanced? Hacksaw Gaming's version is a great pick. It actually steps away from their usual high-volatility style to give you a smoother ride. This double rainbow game is all about colourful visuals, where colorful multipliers drop onto the reels and unlock tons of winning chances.

RTP, Volatility & Winning Potential

Double Rainbow has a solid RTP and a medium volatility rating. This math model is a clear move from Hacksaw's typical extremes, landing it in more player-friendly territory. In this double rainbow game, wins land more regularly. The bonus features also trigger more often, which makes for a less frustrating and more enjoyable session. It's a fantastic introduction to Hacksaw for new players and a nice change for regulars.

Features & How to Play

The heart of the Double Rainbow slot is its multiplier system. You have Wilds that help complete wins, but the special multiplier symbols are where the excitement builds. They can land on any spin and boost any win they touch. When these multipliers stack, a single spin can suddenly pay out massively. Get three or more Scatters to launch the Free Spins round. Here, the multiplier feature usually gets even better, with higher values or more frequent drops. This is your best shot at climbing toward that 5,000x max win. It's a simple concept, but it keeps you on the edge of your seat.

Take It On The Go

You won't need a separate double rainbow app to play on your phone. The touch controls are simple, with easy-to-use buttons for spinning and adjusting your bet. All those bright rainbow colors and sharp graphics look just as good on a smaller screen. This great mobile design means you can add it to your free slots lineup and play wherever you are.

Managing your balance

Because Double Rainbow is medium volatility, you can use a more relaxed strategy with your balance. Your money tends to last longer, allowing for extended play. A good tip is to set a session budget and choose a bet size that lets you take 200-300 spins. This gives the bonus features plenty of time to activate. Wins come around more often, so you can usually bounce back from a few quiet spins without needing to chase losses. It's ideal if you want the excitement of big potential without the brutal dry spells of other popular slots from this developer.
