Create a chemical concoction and try and cook up an explosion of coins in Dr Reactive, a science-themed slot from WMS and Red 7. Played on an 8×8 cascading reels grid, winning combinations are formed by landing clusters of 5 or more matching symbols. Special reactions can clear reels and rows and remove symbols from play. Get on a run of at least 5 cascade wins in a row to trigger the free games round. Wild multipliers can boost payouts here by 10x. Play from between 20p and £100 per spin.
Enter the lab
Dr Reactive’s lab is the setting here. On the 8×8 reel grid you’ll see 3 brightly coloured flasks filled with chemicals as well as a lightning bolt and DNA symbol. Winning combinations are created by landing clusters of at least 5 matching symbols. The bigger the cluster, the bigger the payout. Land 15 of the DNA symbol in combination for an award of 50 times your total bet.
Cascading Reels
Land a winning combination and the successful symbols are removed and new ones drop in and replace them. These cascades keep on coming as long as a new winning combination is formed.
Multiplier Wilds
The W is the game’s wild – this substitutes for all the standard symbols. These wilds can also come with multipliers of 2x, 3x, 4x or 5x attached in the base game. When the wild forms part of a winner in the base game, it drops off the screen like the standard symbols. If there are more than 1 wild in the same cluster, the multipliers are combined.
DNA Reaction
The symbol we haven’t mentioned yet is the atom. This can trigger some special extras when it lands alongside certain symbols. An atom next to a DNA symbol causes the symbols on the row and column of the DNA to clear. A reaction the follows. Each DNA reaction also pays 1x your total stake.
Lightning Reaction
When the atom symbol lands next to the lightning symbols, all examples of the lowest value symbol on the reels are removed. A new reaction then follows.
Free spins with big multiplier wilds
To the side of the reels you’ll see a meter. 1 segment of this is filled with each consecutive cascade win. It clears following a losing cascade. Land 5 or 6 cascade wins in a row and you’ll win 10 free spins. With 7 or more cascades the prize is 15 free spins – these are played in the Free Falls feature.
The wild multipliers are larger in the free spins than in the base game. They boost payouts here by 2x, 4x, 6x, 8x or 10x. The wilds don’t disappear following a successful cascade either. Instead, they lock in position with their multiplier dropping by 2 on each cascade until they reach the minimum 2x. It’s only then that they fall away. Land 5 cascade wins in succession to add another 5 free spins to your total.
Mega Drop Jackpots
Dr Reactive is a Mega Drop slot, you’ll have a chance to trigger a Minor, Major or Epic Jackpot prize – the latter can reach up to £200,000.
Explosive action
This chemical extravaganza is a very playable one. Dr Reactive probably not a game for fans of old school fruit machines though. The extras within the gameplay take a little getting used to. Dr. Reactive can deliver some decent action though.
In fact, the multipliers can result in 65,001 x bet payouts if you’re lucky! If you fancy trying something a little different, then this mad scientist’s lab is a decent enough place to start. If you want to try your luck with grid slots, Play ‘N Go has plenty to choose from – such as Viking Runecraft.
