Reactoonz – Play'n GO

Reactoonz is a high-volatility slot by Play'n GO played on a 7×7 grid with a cluster pays system. Wins form when five or more matching alien symbols connect horizontally or vertically anywhere on the grid. Winning clusters are removed and new symbols fall from above — this is the tumble mechanic — and consecutive tumbles charge two meters simultaneously: the Fluctometer and the Quantumeter, each delivering distinct features when filled. Available in the slots section at ElaBet.

Game Information

Theme and Setting

Reactoonz is set in a cosmic environment populated by a cast of cartoon alien creatures — each a distinct species with its own visual character. The aliens appear in a variety of types differentiated by eye count and design: some have a single central eye, others have two eyes in different arrangements, and special odd-eyed variants play a key mechanical role. The grid uses a bright, dark-space background with the alien characters as the primary visual element.

High-value symbols are larger, more elaborate alien designs. Low-value symbols are smaller, simpler alien creatures. Wild symbols appear as energy orbs or alien artefacts that substitute for any symbol in the game. The overall aesthetic is playful and visually busy — a deliberate contrast to the mythological or exploration themes common across the Play'n GO portfolio.

Cluster Pays and Tumble Mechanic

Reactoonz does not use traditional fixed paylines. A win occurs when five or more identical alien symbols connect horizontally or vertically anywhere on the 7×7 grid. Larger clusters pay proportionally more than smaller ones for the same symbol type. The large grid surface means multiple clusters of different types can form and pay simultaneously in a single evaluation.

When a cluster win is formed, those symbols are removed and new ones fall from above to fill the vacant positions — this is the tumble. If the new symbols create further clusters, those also pay and another tumble follows. The sequence continues until no new clusters form. Each tumble in a winning chain advances both the Fluctometer and the Quantumeter, making extended tumble sequences the primary driver of feature activations.

The Fluctometer and Gargantoon

The Fluctometer is a meter on the side of the grid that charges specifically when odd-eyed alien symbols are part of winning clusters. As odd-eyed aliens contribute to wins across tumble sequences, the Fluctometer progresses through its stages. When the Fluctometer reaches full charge, Gargantoon is released onto the grid.

Gargantoon is a massive 3×3 wild alien — a single wild block that occupies nine grid positions simultaneously. After each tumble in which Gargantoon is present on the grid, it reduces in size: from 3×3 to 2×2, then to three individual 1×1 wild symbols placed separately on the grid. Gargantoon's presence as a large multi-position wild can create or extend clusters across a large area of the 7×7 grid, and it remains active across tumbles until it has fully fragmented. The Fluctometer then resets and begins charging again.

The Quantumeter and Quantum Charges

The Quantumeter charges when single-eyed alien symbols participate in winning clusters. As these symbols contribute to wins, the Quantumeter accumulates Quantum Charges — up to five distinct charges stored simultaneously. When a charge is ready and a tumble sequence ends, the corresponding Quantum effect activates and applies to the grid before the next evaluation:

• Implosion — removes a group of low-value alien symbols from a central area of the grid, creating vacant positions that fill with new symbols.
• Demolition — places charges on all low-value alien symbols across the entire grid, removing them simultaneously to create a dense reseed of higher-value symbols.
• Alteration — transforms all instances of one alien type into another type, consolidating symbol distribution to favour cluster formation.
• Incision — cuts diagonally across the grid, removing symbols along the cut lines and reseeding those positions.
• Incision Wild — cuts diagonally across the grid and places wild symbols along the cut lines rather than removing and reseeding, directly adding wilds to active grid positions.

Multiple Quantum Charges can accumulate and activate in sequence within the same tumble chain, compounding their effects before the next win evaluation.

Volatility

Reactoonz is high volatility. The cluster pays format on a 7×7 grid means individual spin outcomes depend entirely on whether connecting clusters form — spins without clusters produce no payout. Feature activations — Gargantoon releases and Quantum Charge sequences — are the primary sources of elevated win outcomes and require extended tumble chains to trigger. Extended periods between feature activations are a normal and expected part of the game's structure. Always set a session budget before playing and respect it regardless of outcome.

How to Play

1. Set your bet using the on-screen controls. Refer to the in-game paytable for the current bet range at ElaBet.
2. Press Spin. The 7×7 grid populates with alien symbols.
3. Wins form when five or more identical aliens connect horizontally or vertically anywhere on the grid. There are no fixed paylines — any connected cluster counts.
4. Winning clusters are removed and new symbols fall from above — this is the tumble. If the new symbols create further clusters, another tumble occurs.
5. Each tumble charges both the Fluctometer (via odd-eyed aliens) and the Quantumeter (via single-eyed aliens) depending on which types participated in winning clusters.
6. When the Fluctometer reaches full charge, Gargantoon — a 3×3 wild — lands on the grid. It shrinks one stage per tumble: 3×3 → 2×2 → three individual wilds.
7. When the Quantumeter accumulates a Quantum Charge, the corresponding quantum effect activates: Implosion, Demolition, Alteration, Incision, or Incision Wild. Multiple charges can activate in sequence.
8. Autoplay is available with configurable loss limits and single-win stop conditions.
