Nolimit City
Pearl Harbor
Slots · Released December 12, 2024
The grid is 7x7 but only the central 3x3 is active at the start, expanding outward as the round develops. That is a structural idea rather than a cosmetic one: early spins are evaluated on nine positions, late ones on up to forty-nine, so the same bet buys a different game depending on how far you get. The 41,127x ceiling and 96.04% RTP are both typical Nolimit.

How Pearl Harbor pays
Pearl Harbor is rated very high volatility. Its 96.04% return sits below the 96.2% median of the 220 games published here, which is the only benchmark available: Nolimit City has too few pages on this site to have a median of its own.
The ceiling is 41,127x the stake, so a $1 spin caps at $41,127.
It is the 29th of 30 2024 releases from Nolimit City that we track.
Nolimit City publishes the 96.04% return and the 41,127x ceiling on its own page for Pearl Harbor at nolimitcity.com.
What Pearl Harbor actually does
Pearl Harbor pays by cluster pays, the format on 30 of the 221 games in this catalogue.
The published ceiling of 41,127x is reached by compounding: paying symbols clear, the gaps refill and the multiplier carries across the chain instead of resetting between drops.
Free Spins is the round the rest feeds, with expanding grid changing how it behaves once it starts. The 41,127x ceiling is reachable there and effectively nowhere else.
Buy Bonus shortens the wait at a higher stake. That widens the swing on a very high-volatility game without moving the 96.04% return, and several regulated markets switch the option off entirely.
| Mechanic | What it does |
|---|---|
| Cluster Pays | Groups pay, not lines |
| Free Spins | Spins awarded without a stake |
| Scatter | Pays or triggers from anywhere |
| Scatter Pays | Pays by count, not position |
| Multiplier | Multiplies the win it applies to |
| Buy Bonus | Pay to enter the bonus round |
| Tumble | Winning symbols vanish and refill |
| Expanding Grid | The playing field grows |
Cluster Pays
Wins form when enough matching symbols touch each other horizontally or vertically, with no paylines involved. The minimum cluster is typically five symbols, and clusters usually clear to allow further wins from the same spin.
Scatter Pays
Wins are awarded when a minimum number of matching symbols appear anywhere on the grid, regardless of where they sit. Position stops mattering entirely, so eight matching symbols pay the same wherever they land.
Expanding Grid
The grid adds rows or reels under set conditions, increasing the number of positions and therefore the number of ways a combination can form. The expansion is often tied to the bonus round and may persist for its duration.

Pearl Harbor questions
How does the expanding play area in Pearl Harbor work?
Play begins on a 3x3 core inside a 7x7 frame, and the active area grows outward as the feature progresses. Positions outside the active area are inert until unlocked, so the effective grid size changes within a single round.
Is Pearl Harbor as volatile as other Nolimit games?
Yes, it is rated very high, and the 96.04% RTP is in line with the studio's median. The expanding core concentrates outcomes in the later stages of a round, which sharpens the swing further.
What is the RTP of Pearl Harbor?
96.04%, as published by Nolimit City, which has too few pages on this site to have a median of its own. Against the 220 published returns across the whole catalogue it is 0.16 points below the 96.2% median. 153 of those pages publish a higher figure and 65 a lower one, with 1 matching it exactly.
