Play'n GO · 2020Overview
Reactoonz 2 is Play'n GO's follow-up to the original cluster-pays cult slot. Forget paylines — match 5 or more identical symbols in a cluster anywhere on the 7×7 grid and they explode, making room for new symbols to tumble down and chain wins together.
How it plays
Spin from £0.20 to £100 a go. High volatility means long droughts between paydays, but when clusters fire and tumble chains trigger, multipliers stack fast. You're chasing consecutive exploding clusters on a single spin — one big tumble chain can turn a modest cluster into a four-figure win.
The bonus round
No dedicated free-spin bonus. The slot's power comes from in-game multiplier aliens and tumble chains. Land enough clusters and the multipliers climb — they carry over from one tumble to the next, which is where the 5,083x potential lives.
Who it's for
High-variance hunters who can sit through 50-spin droughts at £0.50–£2 stakes for one tumble chain that chains into 200x or more. Chain-reaction mechanics reward patience.
Avoid if
You need regular small wins or play in 20-minute bursts. Reactoonz 2's long flat periods between clusters will drain a shallow bankroll fast.

Reactoonz 2 has a larger 7×7 grid (original was 7×7 too, but mechanics refined), faster tumbles, higher volatility, and a 5,083x top prize vs the first game's lower ceiling.
No. All wins come from cluster matches and tumble chains in the base game. Multiplier aliens stack during chains — that's your multiplier engine, not a bonus round.
