Reactoonz slot by Play'n GO

Learning how to play Reactoonz takes about a minute: choose a stake, start the spin and read what the reels leave behind. The stake can be changed between spins at any point, and every Reactoonz payout moves with it.

Reactoonz pays by cluster: enough identical symbols touching each other anywhere on the grid, with no line to follow and no left edge to start from. Winning symbols are then cleared and new ones drop into the gaps they leave.

Everything above is stated in full inside Reactoonz itself — the paytable button opens the list of symbols and the rules for Cluster pays. The numbers there are quoted against the stake you currently have set, which makes them easier to read than any review.

Reactoonz is laid out as 7 reels, 7 rows and no lines at all, with wins coming from clusters of 5 symbols or more, and it reads exactly as it looks. Position is what counts rather than order: one-eyed little ones — green, blue, pink pays when enough of them touch anywhere on the grid, so a cluster that grows sideways pays exactly like one that grows down. The paytable is top-heavy. One-eyed little ones — green, blue, pink carries the headline number, two-eyed elders — red, orange, purple the next one, and everything below is filler.

There is no conventional wild on the base grid; Reactoonz does its work through the feature set instead. The Reactoonz ceiling is 4,570× the total bet, which is a feature number, not a base-game one.

Everything else on the grid is ordinary; Cluster pays is not: five or more touching creatures pay, wherever they land. Practically, that means a session on Reactoonz divides into two very different modes, and judging the game on the base spins alone gives you half the picture.

The feature set on Reactoonz runs to three rounds, and it repays reading the paytable once before you spin.

Cluster pays: five or more touching creatures pay, wherever they land. In a high-volatility game like Reactoonz that matters more than it sounds: Cluster pays is the round the quoted ceiling is calculated from.

Quantum Features (Implosion, Incision, Demolition and Alteration fire as the charge meter fills). In a high-volatility game like Reactoonz that matters more than it sounds: Quantum Features is the round the quoted ceiling is calculated from.

Gargantoon — a full meter releases the three-headed creature, which breaks apart into wilds. In a high-volatility game like Reactoonz that matters more than it sounds: Gargantoon is the round the quoted ceiling is calculated from.

The features are the game. Cluster pays in particular is where the quoted ceiling of 4,570× the total bet comes from, and no amount of base-grid play approaches it.

There is nothing to set per line on Reactoonz, because there are no lines: you set one total bet and every position on the grid counts towards a cluster. Note that 4,570× the total bet is a multiplier, not a rand figure. It holds at every stake, which is what makes Reactoonz comparable with the games either side of it in the lobby.

Reactoonz runs high volatility — the game concentrates its return into a small number of spins, which means most of them give back nothing. The return printed for Reactoonz is a setting, not a property of the game. Play'n GO ships Reactoonz in more than one configuration, and each casino picks the one it runs, which is why the figure in the table above is a reference point rather than a promise about a session.

There is no reason to ladder the stake on Reactoonz: each spin stands alone, and its paytable scales linearly with whatever you set. If you autoplay Reactoonz, set it to break on Cluster pays — the one moment in the game you want to be watching.

On Reactoonz the stake wants to be small relative to the balance: the game can go a long way without paying, and the only protection against that is spin count. Decide the stop point before you open Reactoonz: our deposit and session limits sit in the account area and apply the moment you set them.

Bonus play on Reactoonz is straightforward: slots clear wagering at 100%, and the detail is on the bonus page. Cluster pays is what Reactoonz is built around, and it shows itself in play rather than in a table — a few rounds say more than the specification above.

One thing not to do with Reactoonz is chase Cluster pays by raising the stake after a dry run: its trigger frequency does not change with bet size, only the cost of waiting does. If Reactoonz stops being comfortable, the responsible gaming page lists the limits, the cooling-off options and the outside organisations we work with.

In short: Reactoonz is for a game that can do very little for a long time and then do a great deal at once. The natural companion in our lobby is Sugar Rush; the corner of the catalogue is close, the feel is not.

Sugar Rush is the near neighbour, and either is a reasonable opening. Reactoonz is the better one when you are prepared to sit through the quiet. Full specifications for Reactoonz — the 7 reels, 7 rows and no lines at all, with wins coming from clusters of 5 symbols or more, volatility, the top end (4,570× the total bet), the feature list and the release year — are in the table at the top of this page.
