Reactoonz

Reactoonz is a Play'n GO slot released in 2017 and built on a seven-by-seven grid rather than on reels and paylines. Wins are formed by clusters: five or more matching symbols touching one another horizontally or vertically pay, wherever they sit on the board. Winning symbols are removed and the remaining ones drop down while new ones fill the gaps, so a single paid round can cascade through several consecutive wins. Each win also charges a meter beside the grid, and filling it triggers one of the game's random modifiers, which transform symbols or add wilds. Charging the meter repeatedly leads to the game's headline feature, a large multi-cell wild character that occupies several positions at once. Volatility is high, meaning long stretches without a paying cluster are part of the design and the swings are wide. The cluster rules, the modifier list, the feature triggers and the RTP configured by your operator are set out in the game's own information panel.
