Mad scientists have captured popular imagination, whether in novels or movies or online slots. Betsoft has released two 3D video slots featuring the mad scientist Dr Walter Prescott. These can be played at online casinos like Bovada Casino and Bodog Casino.

Mad Scientist is the first of these games in which Dr Prescott discovers a formula to convert objects into gold. The symbols on the reels are scientific equipment with some of them being quite zany. The formula chalked on the blackboard is the wild symbol. The Bio Hazard symbol triggers the Bio Pick Me bonus game on the reels. You select one of the symbols for bonus credits. The Tesla Coil symbol activates the Wild’o’Cution feature in which the symbols between the coils turn into wilds. The Great Experiment Bonus is triggered by three or more scattered Test Tube symbols. This bonus game on the second screen is the highlight of the Mad Scientist video slot. You will be taken to the lab for testing the Turn-o-Gold serum. You have to pick four objects and Dr Prescott will test them. The objects will turn into bronze, silver or gold and you will win bonus credits depending on the success of the experiment.

The sequel to the video slot is titled Madder Scientist. Dr Prescott is still busy with his crazy Turn-o-Gold serum. Madder Scientist features an older and crazier looking Dr Prescott. This time he is accompanied by a pretty female assistant. The visuals, particularly the win animations, are peppier and the game features are more attractive. The Beaker symbol triggers the Beaker Click Me feature. This is a multiple pick an object type feature in which you keep selecting beakers for bonus prizes till all beakers are picked or one of them reveals the “Collect”. The Switch scatter symbol triggers the Wild Switches feature. One of the reels is selected randomly and will turn into a wild reel for a set number of spins. Test the Serum bonus is activated by Carrot symbols. This is the bonus game on the second screen and is accompanied by some funny animations. You help Dr Prescott prepare a new concoction to test on the carrot. Again, you are awarded an instant bonus depending on the outcome of the test. Madder Scientist introduces an interactive Reel Re-spin feature. After any spin you can opt to re-spin any one reel keeping the others fixed. But this feature comes at an additional cost.
