Play Lady Merlin Lightning Chase free in demo mode before treating the spec sheet as a simple upgrade story. The slot looks like a fantasy laboratory game, but the real decision is whether standard mode gives enough value or Boom+ is needed.
That decision changes more than spin cost. Boom+ raises volatility, unlocks free spins, improves wild behavior and turns the 3,808x standard ceiling into a 25,600x top award route, so our review treats it as a second mode rather than a small option.
What Lady Merlin Lightning Chase Is Like
Lady Merlin Lightning Chase belongs to our Boomerang Lightning Chase catalogue branch. Boomerang Studios is the developer consensus across official and review sources, while Yggdrasil hosts a game page and BigWinBoard notes Relax-powered distribution.
The game uses five reels with a 3-4-3-4-3 row shape and 432 ways to win. That makes it an asymmetric 5-reel ways frame, not a fixed-payline slot, even though some source cards simplify the layout.
The theme is a secluded workshop where Lady Merlin turns lightning into prize values. We would treat that as a visual wrapper for the mechanic: Lightning Coils carry cash values, and the Collect switch determines when those values are paid.
Standard mode has a 95.69% RTP, medium volatility and a 3,808x public max win. Boom+ nudges the RTP to about 95.94%-95.95%, moves the volatility to medium-high and opens the 25,600x ceiling.
Those numbers explain why the review cannot stop at the base game. The standard version is playable, but Boom+ controls the parts most players will search for: free spins, enhanced wild substitution and the high-end exposure.
How The Lightning Chase Features Work
The base game begins with 432-way wins, potion high symbols and Wilds that appear on reels 2 and 4. In ordinary play, Wilds substitute for most symbols and double wins they join.
Lightning Coil symbols can land with prize values attached. If a Collect symbol lands at the same time, the visible coil values are paid immediately instead of waiting for a separate round.
Six or more Lightning Coils trigger the Hold & Respin feature. The coils lock, three respins begin, and every new coil resets the counter back to three. This is the familiar respin tension, but the Collect symbol adds instant-cash pacing inside the round.
Boom+ changes the symbol rules. With the ante active, Wilds can also stand in for Collect and Scatter symbols, which gives the feature economy more ways to connect instead of relying only on natural Collect or Scatter landings.
The feature stack is easiest to read in this order, because each step changes how value is stored, paid or carried into the next part of the spin cycle before Boom+ adds its own free-spins layer:
- Lightning Coils create visible prize values.
- Collect symbols pay the values currently on screen.
- Six or more coils start three-reset Hold & Respin play.
- Boom+ unlocks the free-spins path and broader Wild substitution.
That combination puts Lady Merlin inside the Boom+ free-spins and respin route category. The slot is not just a Hold & Respin title, because Boom+ adds a second reward path that standard mode does not fully share.
Free spins start with 10 spins when the Boom+ route lands the right Scatter/Wild combination. During the round, each Wild or Scatter adds one extra spin and increases the Wild multiplier by +1, turning later wins into the more important part of the feature.
Is Boom+ Worth Using?
Boom+ costs 60% extra per spin according to the strongest review sources. That is a real session-speed change, not a cosmetic toggle, so it should never be treated as automatically better for every budget.
The reason players consider it is clear: Boom+ makes the game feel complete. It opens free spins, lets Wilds substitute for Collect and Scatter symbols, raises volatility and expands the top award from 3,808x to 25,600x.
That makes Lady Merlin different from Crystal Wolf Lightning Chase sibling Crystal Wolf, where the extra decision is more about Side Strike. Here, the ante mode changes the main feature suite.
Our practical read is simple. Use standard mode if the goal is cheaper exploration of the Lightning Coil and Collect rhythm. Use Boom+ only after demo testing confirms that the higher spin cost fits the session plan.
This is also the right place to set limits. Gamble responsibly, decide the session budget before switching on Boom+, and remember that gambling should be entertainment, not income. If the higher stake pace starts driving decisions, switch back to standard mode or stop.
Our Verdict On Lady Merlin Lightning Chase
Lady Merlin Lightning Chase is strongest when judged as a two-mode slot. Standard play shows the Lightning Coil system, but Boom+ is where the identity sharpens through free spins, boosted Wild behavior and the 25,600x ceiling.
The tradeoff is pace. A 60% ante increase can make dry stretches feel shorter in feature access but harsher on balance, especially because medium-high volatility still leaves long gaps between strong outcomes.
That is why the free demo matters. We would test the standard mode first, then run a separate Boom+ session and compare how often the free-spins path and Collect behavior actually appear.
Players who like visible prize values, respin resets and layered bonus access should find enough to study. Players who dislike ante mechanics may prefer a simpler route where the full game is available at the base stake.
As a 25,600x medium-high volatility profile, Lady Merlin earns its place in the Boomerang mesh. It is not the cleanest low-budget spin, but it gives demo players a clear mode-split decision to test.
- Best hook: Boom+ turns Wilds, Scatters, Free Spins and max-win exposure into one connected decision.
- Check first: loaded RTP, Boom+ cost, free-spins trigger rules and whether the casino uses the full feature profile.
- Skip it if: you want flat stakes, low volatility or a bonus path that does not depend on an ante setting.
