How to Play Professor Clank's Combinator Slot?

If you are interested to find out how innovative this invention really is, all you need is to set your bets.

  • Hit the Total Bet button will open a panel that will let you set your bets.
  • Spin will set the reels in motion once your bets are set.
  • Play will open a panel and let you set the number of automated spins, loss limit, and win limit.
  • Buy Bonus will let you buy your way into a bonus round without waiting for regular triggers.

Slot Features

Clank is your Wild symbol that can help form winnings by substituting in a win for all the symbols in the game except for the Scatter. Wilds appear on middle reels 2 through 5, only.

Explosions, Boosters, Drops and Morphs

When a winning combo gets created, all symbols in non-inning positions will get removed except for the Scatter symbol and all the remaining symbols on the grid will drop to the bottom. If after Explosions there is more than one symbol type remaining apart from the Scatter and the Wild, these will get transformed into the highest paying from the grid. If after the Explosions and Morphs any previously winning symbol is no longer in position, extra matching symbols will get added to one or more surrounding columns. 

After Explosions, Morphs and Boosters, a new symbol will be dropped onto the top of each column that has less than 5 symbols present. Any dropped symbol that doesn’t match or sub in for the current pay symbol will explode. Any dropped symbol that matches the current paying symbol but does not drop into a paying position will explode. Any symbol that matches or subs for the current symbols and lands in paying position will be kept the same as the Scatter which is always kept. However, if all columns contain 5 symbols new drops will not be triggered.

Bonus Respins

Land 5 or more Scatters on the same spin and you will trigger the feature, or you can simply buy your way into it. If you are waiting for the triggers then these Respins will be initiated after all the base game Drops get completed. All non-Scatter symbols will explode at the feature start while all the remaining symbols will drop to the bottom and you will get 3 respins.

All dropped non-Scatter symbols will get removed immediately, while the Scatters get held. Each new Scatter that lands will reset the spins back to 3. Upon completion of the feature, each Scatter will award a prize or one of the 4 Bonus prizes that are non-progressive and located left from the grid. Non-bonus prizes range between x1 and x100, Bronze Bonus is x10 the bet, Silver Bonus is x50 the bet, Gold Bonus is x250 the bet and Platinum Bonus is x2000 the bet.

At the end of the respins you will get to Gamble the wins in order to multiply them and increase. You can choose to gamble up to 3 and you can gamble all of it, or just the half of it, depending on what you feel more comfortable with. The max win for the Gamble feature is x10000 the bet.
