Professor Clank's Combinator Slot Information
Professor Clank's Combinator is a 6-reel ReelPlay slot with variable 3 to 5 rows that can reach up to 707 ways to win. Stakes run from 0.25 to 25 per spin, with an RTP set at 96.1%. It plays on low volatility with a 24.5% hit rate, so wins pop up fairly often, even if many are small. The advertised maximum is 10,000x the bet. The setting is an inventor's workshop, all pipes and coils, and every spin pulls a lever that dumps spent tiles below.
The lower pays are 9, 10, J, Q, K and A. Six of a kind returns between 0.5x and 1.2x the bet. Premiums are a wrench, goggles, a ray gun and a robot, where six pay from 2x up to 10x. The professor himself is the wild, substituting for pays and appearing on reels 2 to 5 only. A glowing blue gear is the scatter and it turns up during both base play and the feature.

Professor Clank's Combinator Slot Features
Winning sets off Explosions. All non-winning symbols are removed, except scatters, while the winning stack drops to the lowest spots. If more than one pay type remains, Morphs convert them into the highest paying of those left. After that, Boosters can add matching symbols to adjacent positions to push any stranded symbol back into a paying shape. The sequence keeps your win live while the grid reshapes, and I found it far easier to follow than it first sounds.
Once Explosions, Morphs and Boosters have resolved, Drops can fall on any column with fewer than five rows. A drop that improves the total sticks; if not, it blows and the search continues. Streak wins can ratchet the ways right up to the 707 ceiling in the base game. Wilds can land on reels 2 to 5 to help complete lines, and scatters are always preserved during the chain, teeing up the feature.
Bonus Respins in Professor Clank's Combinator
Land or build at least five scatters to trigger Bonus Respins after all drops are done. Everything except scatters clears, and the gears slide to the bottom. You start with three respins, with only scatters sticking while non-scatter symbols explode on impact. Each scatter resets the counter to three. Cash scatters carry 1x to 100x, and bonus scatters can land as bronze, silver, gold or platinum worth 10x, 50x, 250x or 2,000x. The feature ends when spins run out or the grid fills.
When the count stops, there's an optional gamble. You can risk all or half of the feature win up to three times, selecting multipliers from 1.25x to 10x with the stated odds. Miss and the bonus payout vanishes. In eligible regions there's a Bonus Buy for 50x that guarantees at least five triggering scatters on the next spin; this option is not offered in the UK. Wheel outcomes scale with the pick, so lower multipliers hit more often, while the top option is rare.
The 200 Spins Professor Clank's Combinator Slot Experience
I saw a few tidy explosion chains in base play, with Morphs and Boosters doing their thing as the ways climbed. I then bought the feature and got the minimum five gears to start. The respins sprinkled in cash values and a bronze prize before stalling, and I took a small gamble once to edge the return. The low volatility shows in the flow with frequent hits, careful growth, and the odd spike when the grid lines up.
