The double rainbow slot from Hacksaw Gaming lands at 96.38% RTP on a 7-reel layout, which puts it above both the corpus average of 95.71% and the provider’s own mean of 96.1%. Its popularity percentile of 96.0 means more players search for this title than 96 out of every 100 slots on the platform — a useful signal about player interest even if interest does not equal expected return.
Double Rainbow versus the average slot
The single number that matters most for comparing slots before you spin is RTP, and here Double Rainbow earns a 0.67-percentage-point lead over the 95.71% corpus average. That gap sounds small. Over a short session it is invisible. Over ten thousand spins at a £1 stake, however, that 0.67% difference translates into roughly £67 of expected return retained versus a game sitting at the corpus mean.
Against Hacksaw’s own portfolio, the comparison is tighter. The provider publishes an average RTP of 96.1% across its 156 indexed titles, so Double Rainbow exceeds that internal benchmark by only 0.28 points. In other words, this is not an outlier within its own studio’s catalogue — it is a typical-performing game that happens to sit in a range where Hacksaw titles cluster relatively high on the broader market.
The rank of 794 among indexed games and the 96th-percentile popularity figure together suggest the title attracts disproportionate traffic relative to its catalogue position. Players are searching for it, but the underlying mathematics place it in the upper-middle band rather than the top tier of return percentages available.

RTP breakdown: 96.38% in context
RTP is a long-run statistical average calculated across millions of simulated spins. A figure of 96.38% means that over an extremely large sample, £100 wagered returns approximately £96.38 to players collectively, with the remaining £3.62 representing the house edge. No individual session will land on that number. A 200-spin session might return 110% or 60% and neither outcome contradicts the RTP.
Where 96.38% sits on the distribution: most regulated online slots in English-language markets publish RTPs between 94% and 97%. Above 96% is generally considered competitive. Double Rainbow’s position at 96.38% places it roughly in the 60th to 70th percentile of available titles by RTP alone — solid but not exceptional.
Hacksaw Gaming has not published a volatility rating or max win figure for this title in the data available to this review. Without a volatility label, you cannot predict swing size from the RTP alone. Two games can share a 96.38% RTP and behave completely differently in session-level variance depending on how the return is distributed across hit frequency and prize size.
Volatility profile
No volatility classification is provided for Double Rainbow in the available game data. This is a meaningful gap for anyone planning a session, because volatility determines how the RTP is delivered over time — whether through frequent small wins that keep a balance slowly declining, or rare large hits that leave a balance flat for long stretches before spiking.
General guidance: if you prefer longer sessions at a fixed budget, lower-volatility games let that budget last more spins because returns arrive more often, even if each return is small. Higher-volatility games require a larger bankroll to survive the dry stretches between hits. Without a confirmed label for this title, treat your first spins at the low end of any stake range you encounter and observe how the game behaves before increasing exposure.
The 7-reel format gives the game more cells per spin than the conventional 5-reel layout, which can support more ways to form a win. How those wins are distributed, however, depends on the paytable and feature design — neither of which is specified in the data available here.
Hacksaw Gaming as a studio
Hacksaw Gaming maintains 156 indexed titles on this platform with an average RTP of 96.1%. That portfolio-wide mean sits above the corpus average, meaning Hacksaw titles as a group tend to offer slightly better theoretical returns than the market. Double Rainbow at 96.38% is just above that studio mean, so you are getting a representative Hacksaw product rather than an exception.
Two other Hacksaw Gaming slots worth comparing on return percentage: Wanted Dead or a Wild matches Double Rainbow’s 96.38% RTP exactly, while Le Bandit comes in slightly lower at 96.34%. Strength of Hercules sits at 96.31%. The spread across these four titles is only 0.07 percentage points, which tells you that Hacksaw clusters its releases tightly in the RTP range — differences between games in the studio are more likely to come from volatility and feature design than from the headline return figure.
Three Relax alternatives worth comparing
Double Rainbow is tagged under the Relax theme category, which includes 380 indexed games on this platform. Three alternatives in that category differ meaningfully in return:
- Big Bass Splash carries an RTP of 96.71%, which is 0.33 percentage points higher than Double Rainbow. Over 5,000 spins at £1, that gap represents roughly £16 in additional expected return.
- Frutinions has no RTP published in the available data, so you cannot compare theoretical returns directly.
- Cleopatra (Arrow’s Edge) similarly lacks a published RTP figure here, leaving it unverifiable from this review’s dataset.
When two of three alternatives lack data, the comparison narrows to a single confirmed option. Big Bass Splash is the clear winner on return percentage within this subset, though RTP alone does not determine session enjoyment or feature quality.
Getting the most out of the free demo
Double Rainbow free demo is available on this site. Playing in demo mode lets you observe how the 7-reel layout behaves in practice — how often wins land, how long between features, whether the pace suits your preference — without risking money. This is genuinely useful information that no RTP number can convey.
Demo play does not predict real-money results. The randomness engine and paytable should be identical, but your perception of volatility from 100 free spins is statistically meaningless. The demo tells you whether you enjoy the rhythm of the game, not whether you will win.
You can play Double Rainbow free without downloading anything, directly in your browser. When you do transition to real-money play, remember that gambling is a form of paid entertainment with negative expected value built in by design. Set a budget before you start, treat it as the cost of an evening’s activity, and stop when it is gone. Players must be 18 or older in all regulated jurisdictions.
Should you play Double Rainbow?
Double Rainbow is a competent entry in the Hacksaw catalogue: above-corpus RTP, above-provider-mean, strong popularity signal, and a 7-reel format that distinguishes it from the 5-reel majority. The missing volatility data is the main reason to try it in demo mode first rather than jumping straight to a real-money session at a meaningful stake. If you want a game with confirmed high volatility and published max win figures, look elsewhere. If you want a statistically sound slot in a slightly unusual reel format with a studio track record of competitive returns, this earns a demo spin.
Frequently Asked Questions
Is Double Rainbow available to play for free?
Yes. The Double Rainbow free demo is available on this site and can be played in your browser without a download or registration. This lets you experience the 7-reel layout and observe its pacing before deciding whether to play with real money.
What is the RTP of Double Rainbow?
Double Rainbow has an RTP of 96.38%, which places it 0.67 percentage points above the 95.71% corpus average and 0.28 points above Hacksaw Gaming's own 96.1% portfolio mean. Over a very large number of spins, this means approximately £96.38 returned per £100 wagered across all players collectively.
Is Double Rainbow a high or low volatility slot?
No volatility rating is published for Double Rainbow in the available game data. Without this classification, you cannot predict whether returns will arrive as frequent small hits or rare large spikes. The safest approach is to play the demo first and observe how the game behaves over enough spins to form a subjective impression.
How does Double Rainbow compare to other Hacksaw Gaming slots?
Double Rainbow at 96.38% sits near the top of the four Hacksaw titles compared here. Wanted Dead or a Wild matches it exactly at 96.38%, Le Bandit is slightly lower at 96.34%, and Strength of Hercules trails at 96.31%. The 0.07-point spread across all four shows Hacksaw clusters tightly in RTP.
Can playing the Double Rainbow demo lead to real-money winnings?
No. Demo play uses a virtual balance and produces no monetary payout. It exists purely as a preview tool so you can judge whether the game's pace and presentation suit your preferences before committing funds. Results in demo mode carry no predictive value for real-money outcomes.
