Pumped Up
A beach party spread across a 5×5 cluster grid. Land 5 or more matching symbols in a blob and they cascade, feeding four collection meters that bank free spins and upgrade your symbols. Multiplier symbols get swept into a running counter, and inside the free spins that counter never resets — that's the path to the 7,700x top.
Cascades, Collection Meters & Free Spins
Three things pull the weight in Pumped Up, and they all feed each other. There are no paylines — you need 5 or more matching symbols touching on the 5×5 grid. A winning cluster pops, everything drops down, and the refill can build a fresh cluster off the same spin. Those cascades chain until a drop lands nothing new.
Every high-pay cluster charges the four collection meters running alongside the grid, each split into four levels. Fill a level and you bank 2 extra free spins plus an instant upgrade that turns low and mid symbols into high-pay ones. Multiplier symbols land carrying 2x to 20x, and when a cluster wins they're swept up and their values summed into a running counter. In the base game that counter clears each spin. Land 3 vinyl-record scatters for the free spins, where the counter never resets and your charged meters carry over — that's the route to the 7,700x cap, and at 96.02% RTP the maths stays honest.

Bonus Mechanics Explained
4 mechanics drive the 7,700x max win. Here's exactly how each one works.
Collection Meters
How to Trigger
Every winning cluster built from high-paying symbols charges the meters. Four meters run alongside the grid, each split into four levels.
What Happens
As high-pay clusters land, they feed the four meters. Complete a full level on any meter and you bank 2 extra free spins for later plus an instant transformation that upgrades a batch of low and mid-pay symbols into high-pay ones. That upgrade often triggers fresh clusters straight away, since the board suddenly holds more premiums.
Multipliers
The meters don't apply a cash multiplier themselves. Their payoff is the symbol upgrade and the extra free spins, both of which raise the odds of stacking premium clusters.
Odds (est.)
Charging meters leans on the ~30% hit frequency, so levels fill steadily in an active session but slowly during cold streaks. Completing all four meters in one run is a bonus-round event, not a base-game one.
Variants
During free spins the charged meters carry over between spins instead of resetting, so progress compounds across the whole feature.
Strategy
Chase clusters of high-pay symbols, not just any win. Only premium clusters feed the meters, so a board full of low-symbol wins looks busy but barely moves the needle.
| Meters | 4 |
| Levels Each | 4 |
| Charged By | High-pay clusters |
| Per Level | +2 spins & symbol upgrade |
| In Free Spins | Carries over |
Cascading Reels
How to Trigger
Fires on any winning spin. A cluster of 5+ adjacent matching symbols pays, then clears.
What Happens
Winning symbols burst and vanish, and the symbols above drop down to fill the gaps while new ones fall in from the top. If the refill forms another qualifying cluster, it pays and cascades again. The chain runs until a drop produces no new win.
Multipliers
No standalone multiplier in the base game. Value comes from chaining multiple clusters off a single paid spin and from each high-pay cluster feeding the collection meters.
Odds (est.)
With a hit frequency near 30%, cascades are frequent but usually short in the base game. Longer chains tend to arrive alongside meter level-ups that reshuffle the board into premiums.
Variants
Inside free spins, cascades work the same but stack on top of the persistent multiplier, so each chained cluster is worth progressively more as the round goes.
Strategy
Let the cascades resolve fully before reading a spin. A modest opening cluster can snowball once symbol upgrades from a filled meter reshape the grid mid-cascade.
| Trigger | 5+ adjacent match |
| Action | Win, clear, refill |
| Chain | Until no new win |
| Feeds | Collection meters |
| Grid | 5x5 |
Free Spins
How to Trigger
Land 3 scatter symbols anywhere on the 5×5 grid. Triggers ~1 in 175 base spins.
What Happens
You start with 10 free spins, and every collection meter level you filled before the round adds 2 more. Once inside, the multiplier counter climbs as you win and does not reset between spins, only when the feature ends. Charged meters also carry over spin to spin, so upgrades and progress compound across the whole round.
Multipliers
A persistent multiplier counter rises through the feature and applies to wins as it grows. Combined with symbol upgrades from the meters, this is the engine behind the 7,700x cap.
Odds (est.)
Natural trigger sits around 1 in 175 base spins. The number of spins you enter with depends entirely on how many meter levels you banked first.
Variants
A bonus buy drops you into the same feature without the wait, at a cost of up to 250x stake where it's permitted.
Strategy
Bank meter levels before triggering if you can, since each one adds spins and keeps the multiplier alive longer. The round is a slow build, so don't bail early on soft opening spins.
| Trigger | 3 scatters |
| Base Spins | 10 |
| Per Meter Level | +2 spins |
| Multiplier | Persists all round |
| Meters | Carry over |
Bonus Buy
How to Trigger
Menu option from base play. Blocked in the UK and some other regulated markets.
What Happens
Pay to skip straight into the free spins round instead of waiting on scatters. The feature plays out identically to a natural trigger, including the persistent multiplier and carried-over meters. The price runs up to 250x stake, which puts it at the steep end of the cluster genre.
Multipliers
Same multiplier and upgrade mechanics as a natural free-spins entry. Buying doesn't pre-load any meters, so you still have to build the round from the ground up.
Odds (est.)
Always available where legal. Like any buy, average return over time trails the cost, so the appeal is variance and instant access, not an edge.
Variants
Single buy tier feeding the standard free-spins feature.
Strategy
At up to 250x it's an expensive punt. Keep a deep bankroll buffer, because a cold streak of low-paying bought rounds is statistically normal at this volatility.
| Cost | Up to 250x stake |
| Feature | Free Spins |
| Meters | Not pre-loaded |
| Restricted | UK and others |
| Risk | High |
