Professor Clank’s Combinator

Professor Clank’s Combinator by Yggdrasil is a video slot set in a steampunk factory filled with machines, gears, and eccentric inventions. The game features six reels with variable rows (often three to five), and offers up to 707 ways to win thanks to the "dropping + cascading" mechanism. The symbols can explode, morph, and be enhanced by boosters when wins form, leading to consecutive reactions ("Explosions", "Morphs", "Boosters & Drops") in the base game. The Professor Clank symbol acts as a wild and can replace all paying symbols except the scatter. The scatter is the special equipment piece that activates the Bonus Respins game when you land five or more.

In the Bonus Respins feature, all non-scatter symbols are removed, and you start with three respins; each new scatter that lands stays in place and resets the respins to three. Scatters also provide cash payouts or award one of four bonus prizes (Bronze, Silver, Gold, Platinum) with varying multipliers of up to approximately two thousand times your stake. After the Respins, you can opt for the Gamble feature, where you can gamble up to three times to multiply your winnings (up to approximately ten times), with the option to risk only half of your winnings. In some regions, a Bonus Buy option is available, allowing you to purchase the Bonus Respins directly instead of waiting for scatters. The maximum win of the game can reach up to approximately ten thousand times the stake. The game combines visual flair and sound design in accordance with the steampunk aesthetic with an innovative gameplay mechanic that expands as you drop more symbols.
