How to Play Reactoonz

Reactoonz has a 7×7 grid filled with bright and colourful alien symbols, set against an intergalactic backdrop. The game uses the cluster pays system to award payouts; get five or more matching symbols in a cluster either vertically or horizontally to achieve a win.

Reactoonz has the popular cascading reels feature; each time a winning cluster of symbols is formed, the symbols in that combination are removed from the reels to allow new symbols to drop and potentially form more winning combinations. Cascades only end when no new winning combinations are formed. 

Reactoonz Gameplay

The colourful space symbol is a wild symbol and can replace other symbols on the reels to help form new winning combinations. This can potentially lead to bigger wins. 

Players of all budgets can enjoy spinning the reels of Reactoonz as bets per spin range from 20p to £5 per spin. This is a high volatility slot game which means it is designed to pay out infrequently but players can potentially expect larger cash prizes.

Due to the infrequent payouts, it is often best with this type of game to stick to lower bets to ensure you do not burn through your payroll too quickly. 

Reactoonz Bonus Features

Reactoonz is bursting with bonus features, with wilds, cascading reels, a quantum leap feature, an instability feature, a giantoonz feature and a fluctuation feature. 

The highlight of the game is the huge quantum leap feature which can potentially trigger 5 bonus features. Each time you get a winning combo, the quantum leap charge meters each increase by 1. Charge a meter to trigger one of the following bonus features: 

  • Implosion feature – up to 6 symbols are turned into wild symbols and any adjacent symbols are removed from the grid
  • Alteration feature – 1 type of low value symbol is randomly chosen to be transformed into another type of symbol
  • Demotion feature – all low value symbols are removed from the grid
  • Incision feature – a wild symbol appears in the centre of teh grid, creating two diagonal lines through the middle section. Both lines have the same random symbol. 

Once all the meters are fully charged, the Gargantoon feature begins where a 3×3 wild is randomly added to the grid. Each time a cascade occurs, the Gargantoon splits. This means it becomes two 2×2 wilds, then 9 1×1 wilds. If no wins happen, players get a random quantum feature. 

Next, we have the instability feature. Watch out for the Gargantoon randomly dropping 4 to 8 wild symbols on the grid on any non-winning spin. 

When 4 matching adjacent symbols appear in a 2×2 format, they form a Giantoonz symbol where they double any wins they are part of. 

The last feature is the fluctuation feature. A random low value symbol is chosen as the fluctuation symbol and if it forms part of a winning combination, 2 wild symbols are placed on the grid. 

Reactoonz Jackpots

There are no jackpots in the Reactoonz slot game, instead, you can spin the reels for potential max wins of up to 4,570x your stake. 

Reactoonz RTP

The RTP in Reactoonz is 96.51%, so in theory for every £100 wagered, around £96.51 is paid out as winnings.

The average RTP of online slot game is 96%. RTP means ‘return to player’. This percentage provides players with an indication of how much a slot game pays back to players as winnings.

Reactoonz Slot payouts

The maximum potential payout in Reactoonz is 4,570x your stake. During the Giantooz feature, players may get a 2x multiplier applied to wins via the 2×2  gigantic symbols. 

You should utilise responsible gambling tools such as deposit limits and cool off periods to ensure you do not exceed your budget. Gamble responsibly, never chase losses and always remember that slot games are 100% random.
