Symbols in the game include six classic A-10 royals offering multiplier values ranging from x0.1 to x1.2 the bet for combinations of three to six-of-a-kind. These are topped by four high-pays worth x0.25 to x10 the bet for three to six-of-a-kind. 

Moving onto special icons, wilds substitute for all symbols except the scatter, and do not appear on column one or six. Meanwhile, the scatter symbol is used to trigger bonus respins. 


Starting with the bonus respins feature, this is triggered when five or more scatter symbols appear on the reels. Bonus respins are triggered only after all base game drops are complete, seeing all non-scatter symbols explode. 

Here, remaining symbols drop to the bottom most position on their column, where three respins are awarded. A new symbol will be dropped onto the top of each column that has less than five symbols present. 

Non-scatter symbols that are dropped, on the other hand, are immediately removed. Scatter symbols are held, and when a new one lands, the respin count is reset to three. 

Upon completion of respins, each scatter awards a prize or bonus prize. The platinum bonus prize is x2,000 the total bet; the gold bonus prize is x250 the total bet; the silver bonus prize is x50 the total bet; the bronze bonus prize is x10 the total bet; and non-bonus prizes range from x1 to x100 the total bet.

Moving onto the drops feature, after explosions, morphs and boosters, a new symbol will be dropped onto the top of each column that has less than five symbols present. Any dropped symbol – except scatter – that does not match or substitute for the current paying symbol is exploded. 

Any dropped symbol that matches or substitutes for the current paying symbol, but does not drop into a paying position as it lands (prior to any latter column symbols being dropped) is exploded. 

Any symbol that matches or substitutes for the current paying symbol and lands in a paying position is kept (scatters are always kept). If the total symbol win value is higher than that of the previous drop (or base game prior to any morphs/boosters if this is the first drop) then an extra drop is triggered. 

New drops cannot be triggered if all columns contain five symbols. Symbol wins are paid once no more drops are triggered.

Moreover, players can gamble their winnings up to three times to multiply half or the total win. The maximum win from the gamble feature is x10,000 the total bet.

Finally, in jurisdictions where permitted, players may opt to buy a bonus respins feature at the cost of x1,000 the bet. The game is played at x20 the base bet, always guaranteeing five or more scatter symbols. 


David Johnson, CEO at ReelPlay, noted: “Professor Clank’s Combinator is ReelPlay’s fresh take on cascading gameplay, where only winning symbols remain. Ways, reactions, morphs & boosters along with feature bonus re-spins and feature gamble are all in the mix.

Professor Clank is the most extraordinary inventor-engineer; with his funky gear and trusty robot, he’s nothing like you’ve ever seen before.”
